Referring to fig. 1, the present invention provides a strap adjusting mechanism 30, which can be used to connect two straps, namely a first strap 11 and a second strap 13.

Referring to fig. 1 to 6, in an embodiment of the present invention, the strap adjusting mechanism 30 includes a buckle body 31, a connecting member 33, and a buckling member 35. The buckle body 31 is used for being connected to one end of the first belt body 11, a sliding cavity 31a with a first opening is arranged in the buckle body 31, and a clamping groove 31b is arranged on the cavity wall of the sliding cavity 31 a; one end of the connecting piece 33 is used for connecting to the second belt body 13, and the other end is slidably inserted into the sliding cavity 31a through the first opening, the connecting piece 33 is further provided with a latch 331, and the latch 331 is embedded in the slot 31 b; the fastener 35 is connected to the fastener body 31 and can cooperate with the engaging groove 31b to clamp and fix the connector 33.

In an embodiment of the present invention, the buckle body 31 may be configured to be connected to an end of the first strap 11 away from the device body of the wrist-worn device, and form a sliding cavity 31a, so that a space for the connecting member 33 to slide is formed by the sliding cavity 31 a. The clamping groove 31b formed by the cavity wall of the sliding cavity 31a can be used for being embedded and meshed with the clamping tooth 331 on the connecting piece 33, so that when the connecting piece 33 is driven, in the process that each clamping tooth 331 slides into one clamping groove 31b adjacent to the clamping tooth 331, the groove wall of the clamping groove 31b corresponding to the clamping tooth 331 can cause certain blocking effect on the sliding of the clamping tooth 331 so as to enable a user to generate corresponding hand feeling, and therefore the user can conveniently control the push-pull sliding process of the connecting piece 33, and the connecting piece 33 can be accurately slid to the position with the length and the size suitable for the user to wear. The number of the catching grooves 31b may be plural, and the plural catching grooves 31b may be sequentially distributed in the sliding direction along the connecting member 33. Specifically, when the first opening of the sliding cavity 31a penetrates through the buckle body 31 and is away from one end for connecting to the first strap 11, the plurality of slots 31b are sequentially distributed in a direction from the end of the buckle body 31 close to the first strap 11 to the end away from the first strap 11. At this time, the first strap 11 and the second strap 13 are respectively located at two opposite ends of the buckle body 31, so that the length direction of the buckle body 31 is the same as the length direction of the first strap 11 and the second strap 13, and the buckle is better attached to the wearing part of the user. Of course, when the first opening of the sliding cavity 31a penetrates through one end of the buckle body 31 facing the first belt body 11, the plurality of catching grooves 31b are sequentially distributed in a direction from one end of the buckle body 31 far away from the first belt body 11 to one end close to the first belt body 11. At this time, the first strap 11 and the second strap 13 are both located at the same end of the buckle body 31. When the number of the locking slots 31b is plural, the locking teeth 51 on the connecting member 33 may be correspondingly plural. The engaging groove 31b may be formed on the buckle body 31. Of course, a strip plate having a plurality of teeth grooves formed thereon may be additionally provided on the buckle body 31. Further, in order to improve the convenience of sliding the latch 331 on the slot 31b, the connection between the slot bottom wall and the slot side wall of the slot 31b and the connection between the slot side wall of the slot 31b and the cavity wall of the sliding cavity 31a where the slot 31b is located may be in arc transition, and the shape of the latch 331 is adapted to the shape of the slot 31 b. In addition, the buckle body 31 may be made of metal so as to have a certain strength and a long service life. Of course, the present application is not limited thereto, and the material of the buckle body 31 may also be plastic. The buckle body 31 may be in an arc shape, so that the buckle body 31 can better fit the wearing part of the user (for example, the arm of the user), thereby improving the wearing stability and comfort of the wrist-worn device. Of course, the present application is not limited to this, and the buckle body 31 may also be a flat plate structure, and at this time, the buckle body may be attached to the wearing part of the user by driving the buckle body to deform during the wearing process. Alternatively, only the portion of the buckle body 31 for engaging with the user may be provided with a curved surface structure. That is, it can be ensured that the buckle body 31 can be attached to the user to be worn. The connection member 33 may be adapted to be connected to one end of the second tape body 13 and slidably inserted into the sliding cavity 31 a. At this time, the latch 331 is formed on the connecting member 33, which is advantageous for improving the convenience of molding the latch 331. The connecting member 33 may be fixedly connected to the second belt body 13, or may be rotatably connected, and the rotation axis may be perpendicular to both the sliding direction of the connecting member 33 and the direction from the groove bottom to the notch of the slot 31b, so that in the process of adjusting the length of the strap by sliding the connecting member 33 in the sliding cavity 31a, when the latch 331 on the connecting member 33 gets into another slot 31b from one slot 31b, the connecting member 33 may rotate correspondingly in the direction from the groove bottom to the notch of the slot 31b, thereby ensuring that the latch 331 on the connecting member 33 gets into another slot 31b, and also improving the reliability of the sliding of the connecting member 33 in the sliding cavity 31 a. At this time, the second belt body 13 may be connected to the first hinge base 131, the first hinge base 131 and the connecting member 33 may be provided with shaft holes, and at this time, a rotating shaft may be directly inserted into the shaft holes of the first hinge base 131 and the connecting member 33 to achieve the rotating connection between the connecting member 33 and the second belt body 13. Of course, the present application is not limited thereto, and it is also possible that the connection member 33 and the first hinge base 131 of the second belt body 13 are connected by a hinge. Alternatively, the connecting member 33 and the second belt body 13 may be directly combined by inserting the rotating shaft and the shaft hole or directly connected by a hinge. The connecting member 33 may be made of metal, so that it has a certain strength to prolong the service life. Of course, the present application is not limited thereto, and in other embodiments, the material of the connecting member 33 may also be plastic. The fastener 35 can be used for abutting against the connector 33 and clamping the connector 33 by cooperating with the slot 31b, so that the connector 33 is fixed in a limited manner relative to the buckle body 31, and further the second strap 13 is fixed in a limited manner relative to the buckle body 31. The fastener 35 may be disposed outside the sliding cavity 31a, or may be disposed inside the sliding cavity 31 a.

When the strap adjusting mechanism 30 of the present invention is used, the buckle body 31 can be connected to the first strap 11, and one end of the connecting member 33 is connected to the second strap 13. Then, the end of the connecting member 33 away from the second belt body 13 is inserted into the sliding cavity 31a of the buckle body 31, and the latch 331 on the connecting member 33 is engaged with the latch slot 31b on the cavity wall of the sliding cavity 31 a. Finally, the fastener 35 is matched with the slot 31b to clamp the fixing connector 33, so that the connection between the first belt body 11 and the second belt body 13 can be completed. When the length of the strap (i.e. the total length of the two belts of the first belt 11 and the second belt 13) needs to be adjusted, the fastener 35 and the connector 33 are driven to separate from each other, so that the connector 33 is not clamped and fixed by the fastener 35 and the slot 31b of the buckle body 31. At this time, the user may drive the connecting member 33 or the second strap body 13 connected to the connecting member 33 to perform a push-pull sliding movement with respect to the buckle body 31, so that the distance between the second strap body 13 and the first strap body 11 is changed. Meanwhile, the second belt body 13 has a certain resistance to generate a hand feeling during the sliding process by the engagement of the latch 331 and the latch slot 31b on the second belt body 13. Moreover, the size of the card slot 31b is relatively small, so that the amount of movement of the latch 331 from one card slot 31b to another adjacent card slot 31b at a time is relatively small. Therefore, the sliding amount of the second belt body 13 can be conveniently controlled, so that the length of the second belt body 13 can be accurately adjusted to be suitable for being worn by a user. Then, the fastener 35 is driven to abut against the connector 33, so that the connector 33 is clamped and fixed by the fastener 35 and the slot 31b on the fastener body 31 to realize secondary limiting of the second belt body 13, and thus the length of the bandage can be adjusted. Therefore, compared with the prior art that the length of the strap is usually fixed and not adjustable, the strap adjusting mechanism 30 in the present solution enables the length of the strap to be adjusted more accurately to adapt to different users for wearing by driving the connecting piece 33 of the strap adjusting mechanism 30 or the second band body 13 connected with the connecting piece 33 to slide when facing different users, thereby improving the versatility of the wrist-wearing device.

Further, since the connecting member 33 connected to the second belt body 13 is slidably inserted into the sliding cavity 31a of the buckle body 31, the connecting member 33 can be accommodated in the sliding cavity 31a, so that the connecting member 33 and the first belt body 11 can be distributed more compactly, which is beneficial to reducing the overall volume. Meanwhile, the first part does not have the problem of overlapping the watchband (that is, one end of the second band body 13 of the wrist-wearing device in the prior art is overlapped on the outer surface of the first band body 11), so that the appearance regularity of the wrist-wearing device can be improved, and the market competitiveness of the product can be improved.

Referring to fig. 5 and fig. 6, in an embodiment of the present invention, the number of the connecting members 33 is two, and the wall surfaces of the two connecting members 33 facing away from each other are disposed on the latch 331 engaged with the slot 31 b; the part of the fastener 35 extends into between the two connectors 33 and abuts against the wall surface of the two connectors 33 away from the wall surface provided with the latch 331 so as to cooperate with the slot 31b to clamp and fix the two connectors 33.

It can be understood that the two connecting members 33 are arranged so that the snap-fit engagement can be achieved between the snap teeth 331 of the two connecting members 33 and the snap grooves 31b of the two opposite cavity walls of the sliding cavity 31 a. Furthermore, the two connectors 33 are clamped and fixed by the matching of the buckling piece 35 extending between the two connectors 33 and the clamping grooves 31b on the two opposite cavity walls of the sliding cavity 31a, so that the clamping area of the two connectors is increased, the abutting force on the connectors 33 is enhanced, and the stability of the limiting and fixing of the second belt body 13 connected with the two connectors 33 by the buckling piece 35 is improved. When the second belt body 13 is connected to the first hinge seat 131, one end of each of the two connecting members 33 near the second opening may be rotatably connected to the first hinge seat 131. For example: the two rotation shafts respectively pass through the shaft holes of the two connecting members 33 and are further inserted into the two shaft holes of the first hinge base 131 to realize the rotation connection. Of course, in other embodiments, it is also possible that the two connecting members 33 are directly and rotatably connected to the second belt body 13 respectively.

Referring to fig. 6 and 7, in an embodiment of the present invention, the adjusting buckle 30 further includes an elastic member 37, and two ends of the elastic member 37 are respectively connected to the wall surfaces of the two connecting members 33, which are away from the wall surface provided with the latch 331.

It can be understood that, during the sliding process of the connecting element 33, when the latch 331 on the connecting element 33 is disengaged from the slot 31b and slides out, the connecting element 33 will rotate to some extent in the direction from the slot bottom to the slot opening of the latching slot 335 and compress the elastic element 37 to some extent, so that the elastic element is correspondingly formed to generate a certain deformation elastic force. When the latch 331 is separated from the slot 31b and slides out to move to the notch of another slot 31b, the connecting member 33 can drive the connecting member 33 to rotate rapidly and return under the deformation elasticity of the elastic member 37, so that the latch 331 slides into another slot 31b rapidly, thereby facilitating to ensure the stable engagement and sliding of the latch 331 on the connecting member 33 and the slot 31b on the buckle body 31. After the length adjustment of the first belt body 11 and the second belt body 13 by the strap adjusting mechanism 30 is completed, the two connecting pieces 33 can be abutted and limited and fixed by the fasteners 35, and the elastic members 37 can also be used for elastically abutting the two connecting pieces 33, so that the limiting and fixing effect of the connecting pieces 33 on the buckle body 31 can be improved. It should be noted that, the present application is not limited thereto, and in other embodiments, during the sliding of the connecting element 33, a certain force applied by the user to the connecting element 33 along the slot-to-slot direction of the slot 31b may be applied to drive the connecting element 33 to stably engage with the slot 31b during the sliding process.

Referring to fig. 6 and 7, in an embodiment of the present invention, the two connecting members 33 are provided with mounting posts 333 on the wall surface away from the latch 331, and the two mounting posts 333 are respectively inserted into the two ends of the elastic member 37.

It can be understood that the mounting posts 333 are configured such that the two ends of the elastic member 37 can be directly sleeved on the two mounting posts 333, respectively, to complete the assembly of the elastic member 37. This simplifies the attachment structure of the elastic member 37, thereby contributing to a reduction in the manufacturing cost of the strap adjusting mechanism 30 and an improvement in the ease of installation of the elastic member 37. Of course, it should be noted that the present invention is not limited thereto, and in other embodiments, both ends of the elastic element 37 may be welded to the two connecting elements 33, or connected by screws.

Referring to fig. 6 and 7, in an embodiment of the present invention, the elastic member 37 is a spring.

It will be appreciated that the spring has the advantage of relatively good resilience and low cost, so that the driving resilience of the resilient member 37 against the connecting member 33 can be ensured, while also making the cost of the resilient member 37 relatively low. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the elastic element 37 may also be an elastic sheet.

Referring to fig. 5, fig. 6, fig. 8 and fig. 9, in an embodiment of the present invention, the buckle body 31 further has a mounting opening 31c, the mounting opening 31c is communicated with the sliding cavity 31a and is disposed corresponding to a space defined between the two connecting members 33, and the buckling member 35 is mounted in the mounting opening 31 c.

It can be understood that the snap-fit element 35 is disposed in the mounting opening 31c of the buckle body 31 and extends between the two connecting elements 33 to cooperate with the plurality of slots 31b to clamp and fix the connecting elements 33. At this time, the fastener 35, the fastener body 31 and the connector 33 are distributed more compactly, so as to be beneficial to reducing the overall volume of the strap adjusting mechanism 30, and improve the wearing convenience and comfort of the wrist-worn device. The fastener 35 may be substantially a plate-like structure, so that it is more compactly distributed on the fastener body 31. The mounting opening 31c can be disposed on a surface of the buckle body 31 facing away from the surface for fitting to the user, so as to reduce the influence of the fastening member 35 on the fitting of the adjustment buckle 30 to the user. Of course, the present application is not limited thereto, and the mounting opening 31c may be provided on the surface of the buckle body 31 for fitting to the user. The shape of the mounting opening 31c may be substantially rectangular, so that the shape is regular and the processing and forming are convenient. Of course, the present invention is not limited thereto, and in other embodiments, the shape of the mounting opening 31c may be substantially square, elliptical, or other shapes, and specifically, may be adapted according to the shape of the fastener 35. In addition, it should be noted that the present application is not limited to this, and in other embodiments, the fastener 35 may be disposed on a surface of the buckle body 31 where the first opening of the sliding cavity 31a is formed or a surface adjacent to the surface where the first opening is formed, and may be capable of abutting between two connecting pieces 33 located outside the sliding cavity 31a (when the number of the connecting pieces 33 is one, the connecting piece 33 abutting outside the sliding cavity 31a is separated from the wall surface where the latch 331 is provided), so as to cooperate with the plurality of slots 31b to clamp the connecting piece 33.

Referring to fig. 6, 8 and 9, in an embodiment of the present invention, the fastening member 35 is movably connected to the fastening body 31, and the fastening member 35 can open or close the mounting opening 31c by moving relative to the fastening body 31; when the fastener 35 covers the mounting opening 31c, a portion of the fastener 35 extends between the two connectors 33 and abuts against the wall surface of the two connectors 33 away from the latch 331.

It will be appreciated that unlocking of connector 33 is accomplished by driving snap 35 to open mounting openings 31c so that snap 35 is more fully disengaged from cover connector 33 after unlocking connector 33. At this time, when the driving connector 33 slides with respect to the buckle body 31, the engagement member 35 does not hinder the sliding of the connector 33, thereby facilitating the driving of the connector 33. It should be understood that, the present application is not limited thereto, and in other embodiments, the fastening element 35 may be fixedly connected to the fastening body 31 and elastically abutted between the two connecting elements 33 (or elastically abutted on a surface of the connecting element 33 departing from the latch 331 when the number of the connecting elements 33 is one). At this time, when the user pushes or pulls the second strap 13 or the connecting member 33, the elastic abutting force of the fastener 35 against the connecting member 33 can be overcome. When the user cancels the pushing and pulling driving force applied to the second strap 13 or the connecting element 33, the connecting element 33 can be fixed in a limited manner by the elastic abutting force of the fastening element 35.

Referring to fig. 6, 8 and 9, in an embodiment of the present invention, a fastening member 35 is defined to have two opposite ends, one end of the fastening member 35 is rotatably connected to the fastening body 31, and the fastening member 35 can open or close the mounting opening 31c by rotating relative to the fastening body 31; when the buckle body 31 covers the mounting opening 31c, the portion of the other end of the buckle 35 opposite to the buckle extends into between the two connecting pieces 33 and abuts against the wall surface of the two connecting pieces 33 away from the wall surface provided with the latch 331.

It will be appreciated that one end of the clasp 35 is pivotally connected to the clasp body 31 and the other end is removably connected to the clasp body 31. So that after the end of the fastener 35 detachably connected to the fastener body 31 is unlocked to open the mounting opening 31c, the end of the fastener 35 connected to the fastener body 31 by rotation is still connected to the fastener body 31. This eliminates the need for additional space to locate the fastener 35 after opening the mounting opening 31c, thereby improving the ease of opening the fastener 35 and reducing the likelihood of loss of the fastener 35. The axis of rotation of fastener 35 relative to the fastener may be perpendicular to the direction of sliding movement of connector 33 relative to the fastener. Of course, the axis of rotation of fastener 35 relative to the fastener can also be parallel to the direction of sliding movement of connector 33 relative to the fastener. The rotary connection between the fastener 35 and the fastener body 31 may be: referring to fig. 9, 10 and 11, the fastening member 35 has a first connecting ear 351, the fastening body 31 has a second connecting ear 311, and a pin passes through the first connecting ear 351 and the second ear to realize the rotational connection between the fastening member 35 and the fastening body 31. Of course, it is also possible that fastener 35 and fastener body 31 are directly connected by a hinge. Further, the fastener 35 is detachably connected to the buckle body 31 or the connecting member 33 at an end away from the end rotatably connected to the buckle body 31. Therefore, the fastening member 35 and the buckle body 31 have a stable connection relationship, so that the connector 33 or the second strap 13 connected to the connector 33 can be moved only after the end of the fastening member 35 detachably connected to the buckle body 31 is unlocked, thereby being beneficial to ensuring that the fastening member 35 can stably limit the connector 33 and the second strap 50. In other embodiments, the fastener 35 may be slidably connected to the fastener body 31 along the extending direction of the mounting opening 31c (that is, the axial direction of the mounting opening 31 c), and may be in interference fit with the mounting opening 31c when being slid into the mounting opening 31c, and a portion of the fastener 35 may extend between the two connectors 33 and abut against the facing wall surfaces of the two connectors 33.

Referring to fig. 6, 9 and 11, in an embodiment of the invention, the fastening member 35 is provided with an abutting frame 353, and when the fastening body 31 covers the mounting opening 31c, the abutting frame 353 extends between the two connecting members 33 and abuts against the wall surface of the two connecting members 33 away from the wall surface provided with the latch 331.

It can be understood that the fastener 35 extends into the space between the two connectors 33 through the abutting frame 353, so that the fastener 35 does not need to be arranged relatively thick, thereby being beneficial to reducing the production raw materials required by the fastener 35 and reducing the manufacturing cost, and being beneficial to reducing the quality of the fastener 35 and improving the carrying convenience of the wrist-worn device. When the fastener 35 is slidably connected to the fastener body 31 along the axial direction of the mounting opening 31c, the fasteners 35 may be provided with the abutment frames 353 at two opposite ends. When one end of the fastener 35 is rotatably connected to the fastener body 31, the abutment frame 353 may be disposed at an end of the fastener 35 away from the end rotatably connected to the fastener body 31, and the abutment frame 353 is located on a surface of the fastener 35 facing the sliding cavity 31 a. The abutting frame 353 can comprise two sub-frame bodies 355, and the two sub-frame bodies 355 abut against the wall surfaces of the two connecting pieces 33 departing from the clamping teeth 331 respectively, so that the stability of abutting the two sub-frame bodies is improved. Further, each subframe body 355 may include a first segment 356, a second segment 357 and a third segment 358, one end of the first segment 356 is connected to the fastener 35 and extends along the cavity wall facing the sliding cavity 31a and facing the mounting opening 31c, the second segment 357 is connected to one end of the first segment 356 away from the fastener 35 and extends along a side direction facing the center of the mounting opening 31c, and the third segment 357 is connected to one end of the second segment 357 away from the first segment 356 and extends along a direction facing the mounting opening 31 c. Therefore, the structure of the subframe 355 can be relatively simple, and the first section 356 of the two subframe 355 can be used to abut the wall surface of the connecting piece 33 away from the latch 331 in a relatively large area. Further, the two third segments 358 of the two sub-frames 355 may be abutted and welded together. At this time, the rigidity strength of the abutment shelf 353 can be increased, thereby being advantageous to ensure stable abutment of the abutment shelf 353 against the connecting member 33. In addition, the present invention is not limited to this, and in other embodiments, the abutment frame 353 may have a plate-like structure facing the cavity wall of the mounting opening 31c toward the sliding cavity 31a, and in this case, the plate surfaces on the opposite sides of the abutment frame 353 may be used to abut against the connector 33. Alternatively, the abutment shelf 353 may have a columnar structure and extend in the direction in which the two connectors 33 face each other, and in this case, the opposite end surfaces of the abutment shelf 353 may be used to abut against the connectors 33. That is, the present application does not limit the specific structure of the abutment shelf 353, and the connecting member 33 can be abutted by the abutment shelf 353 so as to be matched with the slot 31b to hold the limit connecting member 33.

Referring to fig. 6, 9 and 11, in an embodiment of the invention, the fastening member 35 is further provided with a fastening buckle 340, at least one of the two connecting members 33 is provided with a fastening groove 335 on a wall surface away from the wall surface provided with the latch 331, the fastening groove 335 extends along a sliding direction of the connecting member 33, and when the buckle body 31 covers the mounting opening 31c, the fastening buckle 340 is fastened and fixed with the fastening groove 335, so that the fastening member 35 is detachably connected to the connecting member 33.

It can be understood that the clamping buckle 340 is clamped and fixed with the clamping groove 335, so that the clamping buckle 340 is clamped into the clamping groove 335, and the connection between the clamping piece and the connecting piece 33 can be realized; and the buckle 340 is separated from the buckle groove 335, so as to realize the disassembly of the buckle 35 and the connecting piece 33. Therefore, the assembly and disassembly processes of the buckling piece 35 and the connecting piece 33 are simple, and convenience of opening and closing the buckling piece 35 is improved. Moreover, since the abutment 353 of the fastener 35 is in right-angle contact with the wall surface of the connecting element 33 away from the latch 331, no direct driving relationship exists between the two. At this time, even if the clamping force of the clamping buckle 340 and at least the clamping groove 335 is relatively small, the belt adjusting mechanism 30 is not affected to have large push-pull resistance after being supported and limited by the connecting piece 33. When the fastener 35 is slidably connected to the buckle body 31 along the axial direction of the mounting opening 31c, the fastener 35 may have the fastening buckles 340 at two opposite ends. When one end of the fastening member 35 is rotatably connected to the buckle body 31, the fastening member 35 may be provided with the fastening buckle 340 at the end away from the end rotatably connected to the buckle body 31, and the fastening buckle 340 may be located on the surface of the fastening member 35 facing the sliding cavity 31 a. The number of the snap fasteners 340 may be one, and at this time, a snap groove 335 is formed in one of the connecting members 33. Certainly, the number of the clamping buckles 340 can be two, and the opposite wall surfaces of the two connecting pieces 33 can be provided with the clamping grooves 335 at the moment, so that the clamping buckles 340 on the buckling pieces 35 are in clamping connection with the clamping grooves 335 on the connecting pieces 33 for limitation, and the locking stability of the buckling pieces 35 on the two opposite sides is ensured. Or, the number of the snap fasteners 340 may also be more than two, at this time, a part of the snap fasteners 340 is snapped with the snap groove 335 of one connector 33, and another part of the snap fasteners 340 is snapped with the snap groove 335 of another connector 33. It should be noted that the present application is not limited thereto, and in other embodiments, the fastening element 35 and the connecting element 33 may be fixed by magnetic attraction. Alternatively, the fastener 35 can be detachably connected to the fastener body 31. For example: the fastener 35 can be fixed by snap connection or magnetic attraction through the abutting frame 353 and the cavity wall of the sliding cavity 31a of the fastener body 31, which is opposite to the mounting opening 31 c. Or, the fastener 35 is connected to the inner wall of the mounting opening 31c and the end of the buckle body 31 far away from the rotating connection end, and is fixed by the snap connection or the magnetic attraction.

Referring to fig. 6 and 9, in an embodiment of the present invention, a gap is formed between one end of the fastener 35 and the inner wall of the mounting opening 31 c.

It will be appreciated that the gap is formed such that when the user needs to open the mounting opening 31c, a finger can be inserted into the gap to snap the fastener 35, thereby facilitating the opening of the fastener 35 by applying an opening force to the fastener 35. In order to further facilitate the user to break the fastening element 35, the end surface of the fastening element 35 away from the end rotatably connected to the fastening body 31 may further be formed with a profiling surface 341 in an inwardly concave manner, and the profiling surface 341 may be adapted to the shape of the finger. When the fastener 35 is slidably attached to the fastener body 31 along the axial direction of the mounting opening 31c, a gap may be provided between any one end of the fastener 35 and the inner wall of the mounting opening 31 c. When one end of the fastener 35 is rotatably connected to the buckle body 31, the fastener 35 has a gap between the end away from the rotatable connection with the buckle body 31 and the inner wall of the mounting opening 31 c. In addition, the present invention is not limited to this, and in other embodiments, a pull ring may be provided on a surface of the fastener 35 away from the abutment frame 353, and the fastener 35 may be opened by pulling the pull ring.

Meanwhile, the arrangement is favorable for improving the appearance attractiveness of the buckling piece 35, so that the market competitiveness of the product is enhanced. The surface of the fastener 35 facing away from the sliding cavity 31a and the outer surface of the fastener body 31 forming the mounting opening 31c may be located on the same plane, or may be located on the same arc surface. In addition, it should be noted that, the present application is not limited thereto, and in other embodiments, a surface of the fastening member 35 facing away from the sliding cavity 31a may be recessed into an outer surface of the fastening body 31 where the mounting opening 31c is formed.

The first belt body 11 can be provided with a second hinge seat 111, and the second hinge seat 111 is inserted into the housing 313 through a pin. The rotational connection of the first belt body 11 and the housing 313 can be realized. Of course, it is also possible to hinge the first belt body 11 and the housing 313. In addition, when the first strap 11 has relatively good elasticity or flexibility, it is also possible that the first strap 11 is fixedly connected to the housing 313 of the buckle body 31. When the second opening is not formed in the slide chamber 31a, the first belt body 11 may be fixedly connected or rotatably connected to the outside of the housing 313.

This maintains high rigidity of the tooth plate 322, thereby improving convenience and stability in drawing the link 33. Meanwhile, the back plate 323 can be better attached to the inner side wall of the shell 313 of the buckle body 31, so that the connection stability of the back plate and the shell is improved. The back plate 323 and the housing 313 of the buckle body 31 may be connected by a pin or a snap. Further, the pin for connecting the back plate 323 and the housing 313 may be further abutted and limited by the first connection plate 314 on the housing 313. In addition, the present application is not limited to this, and the toothed plate 322 may be directly connected to the housing 313 of the buckle body 31.
