Background

With the development of economic society, the number of household and industrial machine equipment is increasing, and as most of the machine equipment in the market at present are connected with a power supply in a plug and socket mode, the situation that more plugs and sockets are needed to be used also occurs.

The plug of the machine device is basically mainly an extended conductive plug or pole piece which is inserted into a preset jack on the socket. The quality of the circuit connection depends on the coupling force of the electrode pins inserted into the sockets. If the plug is connected with the socket too loosely, the power failure accident is easy to happen, but the connection is too tight and the plug is inconvenient to use frequently. However, for enterprises or households, the power-off effect is far greater than the over-tight connection effect, so the existing plug and socket are designed to be a tight combination type, especially for heavy equipment or equipment requiring large current. Therefore, the problem that the plug and the socket are inserted too tightly and the plug can be pulled out only by applying a large external force by people is solved. Therefore, the electric shock protector is time-consuming, labor-consuming, inconvenient to use and has electric shock risks. If the socket is fixed, such as in a corner or wall, the actual plugging operation is more difficult.

Therefore, it is urgently needed for related manufacturers to develop a plug easy to plug and unplug, and the chinese patent publication no: CN204835060U, the name of the invention is: the plug is easy to pull out and not fall off the device, discloses a plug is easy to pull out and not fall off the device, includes, plug, socket, card, spring, kicking block, link mechanism, button etc. constitute. The middle of the plug is provided with a cylinder, the head of the cylinder is in an inverted cone shape, and the cylinder is also provided with a circle of grooves; the socket is provided with a cylindrical hole with a small upper part and a big lower part, and the hole is provided with two symmetrically arranged clamping pieces; the upper ends of the two cards are in a radial shape of inverted V, and the lower ends of the two cards are in a radial shape of V; the back parts of the two clamping pieces are propped by springs, and the lower ends of the two clamping pieces are radially attached to the inclined plane of the jacking block; the lower end of the top block is hinged with one end of the connecting rod mechanism; the other end of the link mechanism is connected with the button. When the plug is inserted into the socket, the cylindrical head of the plug is inserted into the cylindrical hole of the socket, the clamping piece in the cylindrical hole is squeezed open, and when the plug is inserted in place, the upper end of the clamping piece is pressed into the cylindrical groove of the plug by the spring; when the plug needs to be pulled out, the button is pressed down, the link mechanism connected with the button pushes the ejector block upwards, the inclined plane of the ejector block extrudes the two clamping pieces, the upper end of the inclined plane pushes against the cylindrical head of the plug to push the plug out of the socket.

In addition, for the plug of the special equipment, a special power supply needs to use a special socket, but an actual operator can easily use a general socket to directly obtain the power supply, so that the plug needs to use the socket matched with the plug to obtain the special power supply, and foolproof measures are provided.

The invention provides an easy-to-pull plug pin connector which is matched with a plug socket for use, wherein a non-matched socket cannot form electrical connection with a plug, and a non-matched plug cannot be inserted into the socket. On the premise of ensuring that the plug and the socket are tightly combined, the effect of pulling out the plug can be realized by only pressing the button by using the reversing separation mechanism, the effect is labor-saving and quick, and in addition, the invention can also effectively prevent water.

Disclosure of Invention

The present invention is directed to a plug connector with easy-to-pull for solving the above-mentioned problems of the prior art.

The invention provides the following technical scheme: easy-to-pull plug connector who forms a complete set and use, including plug, socket, power source, casing, jack and a plurality of bolt electrical apparatus, its characterized in that: the easy-to-pull plug connector used in a matched mode further comprises a reversing separation mechanism and a button, the shell comprises a plug shell and a socket shell, the plug electric appliance comprises plug pins and jacks, the plug pins are arranged at the lower end of the plug shell, the jacks are arranged in the socket and matched with the plug pins for use, the power source interface is arranged on the side face of the plug, the button penetrates through the plug shell and exposes one part of the upper end of the plug shell, and the reversing separation mechanism penetrates through the socket shell and is arranged in the socket shell. The reversing separation mechanism is integrally inverted m-shaped and comprises a pressing column, a supporting shaft, a plurality of supporting arms and a plurality of top columns, and each supporting arm at least corresponds to one top column. The compression leg sets up in the middle of the separating mechanism that commutates, the fore-set symmetry sets up at the separating mechanism side that commutates, compression leg and fore-set run through the socket shell, under plug and socket separation and the complete socket-outlet state of inserting of plug, compression leg and fore-set upper surface flush with the socket shell upper surface. The support shaft is arranged at the lower end of the compression column and fixedly connected with the compression column, one end of the support arm is hinged with the support shaft, the middle of the support arm is movably connected with the socket shell, and the other end of the support arm is hinged with the ejection column. When the pressing column is forced to move downwards, the supporting shaft moves downwards along with the pressing column, the end, connected with the pressing column, of the supporting arm moves downwards, and the end, connected with the top column, of the supporting arm moves upwards under the reversing action of the middle and the socket shell. The pressing column, the supporting arm, the ejection column and the socket shell form a plane reversing mechanism, downward acting force of the button is converted into upward acting force of the ejection column, and meanwhile, the plurality of ejection columns share downward force of the button together, so that the effects of saving labor and improving bearing capacity of the reversing separation mechanism can be achieved.

The lower end of the button is electrically connected with the upper end of the pressing column, the upper end of the button is provided with an insulator, the button is electrically connected with the plug pin, the pressing column is electrically connected with the jack, and the plug and the socket are required to be used in a set. If the plug is completely inserted into the socket, the button is not contacted with the pressing column, and the plug and the socket are disconnected, the plug cannot obtain power from the socket, so that the anti-theft function of the plug and the socket can be realized. For special type equipment, the wrong power socket is used, and the power supply cannot be connected, so that power supply accidents are caused.

When the plug is completely inserted into the socket, the lower end of the button is in close contact with the pressing column, and the plug obtains power from the socket. When the plug needs to be separated from the socket, the button is pressed, the button extrudes the reversing separating mechanism, the reversing separating mechanism transmits force to the socket, the button transmits the force to the plug, and the reversing separating mechanism is of a labor-saving structure, so that the plug and the socket can be separated easily.

Further, the support arm still includes the connecting axle, set up circular through-hole in the middle of the support arm, the connecting axle runs through the through-hole and with socket shell swing joint, the connecting axle is used for connecting support arm and socket shell to make the support arm can be in the relative rotation of connecting axle department, with the direction of force conversion simultaneously. The connecting shaft and the supporting arm can also be designed into a whole, namely, two cylinders respectively protrude from two sides in the middle of the supporting arm and are used as the connecting shaft to be movably connected with the lower socket shell. The connecting shaft ensures that the supporting arm can only rotate relative to the socket but can not move in the horizontal or vertical direction, and plays a role in fixing the reversing separation mechanism and converting the direction of force. The supporting arm is the cambered surface with back shaft, fore-set swing joint department contact surface, cambered surface parcel back shaft or fore-set lower extreme are designed into the cambered surface and are for articulated back relative rotation to reduce the mutual wearing and tearing between each movable contact surface of switching-over separating mechanism, the cambered surface still will rotate the horizontal displacement absorption that the in-process produced and fall, guarantee that compression leg and fore-set only do the removal of vertical direction.

Furthermore, the supporting arms are pairwise used and are arranged in a back direction, one of the paired supporting arms is provided with an arc surface at the end contacted with the supporting shaft, the other supporting arm is provided with two arc surfaces at the end contacted with the supporting shaft, the lower end of each arc surface is provided with a strip-shaped convex edge parallel to the arc, and a T-shaped opening A is formed between the two arc surfaces of the supporting arm with the two arc surfaces. The cambered surface of the supporting arm with one cambered surface is movably connected in the opening A in a crossing manner. Therefore, each pair of supporting arms can be inserted into each other, can rotate mutually and cannot move left and right, so that the limiting function is achieved, and the reversing separation mechanism is more stable.

Furthermore, the lower end of the top column is a horizontal cylinder matched with the arc surface of the supporting arm, the middle end of the top column is a vertical cylinder, the upper end of the top column is a hemisphere, and the plug shell is pushed upwards in a spherical form, so that the plug pins and the jacks are favorably separated. The spring is established to the vertical cylinder body section cover between horizontal cylinder and the socket casing, set up the packing ring between horizontal cylinder and the spring. The vertical cylinder is favorable for the vertical movement of the ejection column and is convenient for sleeving the spring, the horizontal cylinder is convenient for the mutual rotation of the ejection column and the supporting arm, the stress area is increased, and the bearing capacity of the ejection column is reduced. When the plug inserts the socket, because the effect of spring, the fore-set is supported by the spring, can not reciprocate, and when the socket was pulled out to the plug needs, the spring was compressed, and the fore-set shifts up, and after the socket was pulled out to the plug, the pressing force was removed, and the fore-set is stretched to the original position by the spring. The top surface of the top column and the upper surface of the pressure column are flush with the upper surface of the socket shell under the free extension state of the spring.

Further, the button is the third grade step cylinder, and middle wide both ends are narrow, can reciprocate in the plug, and upper end cylinder A exposes the plug casing and supplies to press, exposes highly more than or equal to and participates in embedding jack length, and middle cylinder B butt plug shell is as supporting, prescribes a limit to the upper and lower home range of button, and the lower extreme is cylinder C and compression leg contact. The outer ring of the cylinder C is sleeved with a reset piece, one end of the reset piece is abutted against the cylinder B, and the other end of the reset piece is abutted against the plug shell. When the button is pressed to be in the same plane with the upper surface of the plug shell, the pin is completely separated from the socket, and the reset piece is completely compressed. The cross section of the three-section cylinder of the button is set to be as large as possible, the larger the cross section area is, the smaller the force bearing area is, the smaller the force which needs to be exerted when an operator presses the button is, but the corresponding requirement on the internal activity space of the plug and the socket is also larger. The lower end of the column body C is matched with the upper end of the compression column, the end faces of the column body C are matched with each other, if the plug is inserted into a non-matched socket, the lower end of the column body C can be abutted against the upper surface of the socket, the plug cannot be completely inserted into the socket, and the plug cannot be electrically connected with the socket. If the unmatched plug is inserted into the socket, the press column cannot be electrically connected with the plug, and the unmatched plug cannot obtain power from the socket.

Furthermore, the upper end of the compression leg and the lower end of the column C can be complementary protrusions, when the plug and the socket are not used in a set, the upper end of the compression leg can support an unmatched plug, and the lower end of the column C can support an unmatched socket.

Furthermore, the lower end of the cylinder C is a spherical surface, the upper end of the compression leg is provided with a groove B matched with the spherical surface, when the plug is inserted into the socket, the spherical surface is in close contact with the groove B, and the projection area of the groove B is larger than or equal to half of the cross section area of the compression leg but not larger than the cross section area of the cylinder C. The contact surface of the pressing column and the button is designed into a spherical surface, so that the respective bearing capacity of the reversing separation mechanism and the button can be enhanced, the stress area is increased in a phase-changing manner, the spherical surface can rotate relatively, the mutual friction between the button and the plug shell is reduced, and the service life of the button is prolonged. However, the opening area of the groove B is smaller than the cross section area of the compression leg, so that the side wall of the compression leg is not abraded in the repeated use process, and the effective stroke of the compression leg is reduced. If the plug is inserted into a non-matched socket, the ball body at the lower end of the column C can prop against the upper surface of the socket, so that the plug cannot be completely inserted into the socket, and the plug cannot be electrically connected with the socket. If the unmatched plug is inserted into the socket, the press column cannot be electrically connected with the plug, and the unmatched plug cannot obtain power from the socket.

Further, the plug shell includes plug epitheca and plug inferior valve, plug epitheca upper surface central point puts and opens the circular recess C with cylinder A assorted, recess C lower extreme is provided with cylinder B assorted hollow cylinder D, and the interior circle diameter of hollow cylinder D slightly is greater than the diameter of cylinder B. The upper surface central point of socket inferior valve puts and corresponds with hollow cylinder D and is provided with hollow cylinder E, the interior circle diameter of hollow cylinder E equals hollow cylinder D's interior circle diameter, and hollow cylinder E's upper surface is connected with hollow cylinder D's lower surface, forms the passageway that supplies the limited up-and-down movement of button. The lower end of the hollow cylinder E is provided with a baffle ring for supporting the reset piece. The reset piece can also move up and down in the hollow column body E. The round groove C, the hollow cylinder D and the hollow cylinder E are all used for accommodating the button, so that the button can move up and down in the penetrating plug, the button is prevented from moving left and right, and positioning and guiding effects are achieved.

Further, socket shell includes socket epitheca and socket inferior valve, socket epitheca upper surface set up with compression leg assorted through-hole D and with fore-set assorted through-hole E, the socket inferior valve is whole to be hollow cuboid, the upper end open have with compression leg assorted through-hole F and with fore-set assorted through-hole G, through-hole F sets up under through-hole D, through-hole G sets up under through-hole E, set up the support frame in the middle of the socket inferior valve, support frame and support arm swing joint. The through hole D and the through hole B are used for accommodating the compression leg and the top leg in the socket, so that the compression leg and the top leg can penetrate through the socket to move up and down and cannot move left and right, and the functions of guiding and positioning the compression leg and the top leg are achieved. The lower end of the lower socket shell is hollow, and the lower end of the lower socket shell is hollow upwards and used for accommodating the supporting frame and the reversing separation mechanism.

Furthermore, the lower end of the pin is gradually widened from the middle end to the middle end, the middle end is horizontally wide, and the upper end of the pin is fixedly connected with the plug, so that the pin can conveniently enter the jack. The jack comprises a plurality of pole pieces and a plurality of connecting rings, the pole pieces are elastic, every two pole pieces are oppositely arranged into a group, a gap for the pin to move up and down is reserved between the two pole pieces, the gap is wide from top to bottom and narrow in the middle, so that the pin gradually enters the jack, the pin enters the wide hole at the thin end and then enters the narrow end of the gap at the wide middle end, and the pin is tightly combined with the jack. Each group of pole pieces are connected through the connecting rings, namely at least one connecting ring is arranged on each group of pole pieces. When the lower ends of the pins are in contact with the connection ring, the lower surface of the plug is in contact with the upper surface of the socket. The connecting ring ensures that the pole pieces are tightly combined with the jacks, ensures that each group of pole pieces extrudes the pins, also determines the maximum embedding depth of the pins and plays a role in limiting. Each pin at least corresponds to one group of pole pieces, and the close connection between the pin and the jack is ensured.

Furthermore, the upper surface of the socket shell is provided with a plurality of through holes I matched with the pins, the openings of the through holes I are the same as the maximum cross sections of the pins, and the periphery of the lower ends of the through holes I is filled with sealing elastic materials. The sealing elastic material is a soft solid with high temperature resistance, wear resistance and elasticity, such as: styrene elastomer, ceramic composite fiber. The sealing elastic material forms a long seam around the through hole I. When the plug and the socket are separated, the through hole I is sealed under the elastic action of the sealing elastic material, so that liquid is prevented from entering the socket, and when the plug is inserted into the socket, the pin can easily pass through the through hole I from the strip seam because the sealing elastic material is an elastic soft solid. Meanwhile, the sealing elastic material is required to have high temperature resistance and wear resistance because the through hole I needs to enter and exit frequently and electric sparks are generated frequently. The through hole I is matched with the pin for use, and a distance is reserved between the lower end of the through hole I and the pole piece, so that the connection between the pin and the jack is not hindered.

Referring to fig. 1-7, the present invention provides the following technical solutions: the invention relates to an easy-to-pull plug pin connector which is matched with the plug pin connector, and comprises a plug, a socket, a power interface, a shell, a plug hole and a plurality of plug pin electric appliances 6, and is characterized in that: the easy-to-pull plug connector used in a matched mode further comprises a reversing separation mechanism 7 and a button 1, the shell comprises a plug shell and a socket shell, the plug electric appliance 6 comprises a plug pin 601 and a jack 602, the plug pin 601 is arranged at the lower end of the plug shell, and the jack 602 is arranged inside the socket and is matched with the plug pin 601 for use. The power interface is arranged on the side face of the plug, the button 1 penetrates through the plug shell and is partially exposed at the upper end of the plug shell, and the reversing separation mechanism 7 penetrates through the socket shell and is arranged inside the socket shell. The reversing separation mechanism 7 is of an inverted m shape integrally and comprises a pressing column 701, a support shaft 702, two support arms 703 and two top columns 704, wherein the support arms 703 and the top columns 704 are arranged correspondingly. The pressing column 701 and the supporting shaft 702 are designed into a whole, the upper end is a cylindrical pressing column 701, the lower end is a supporting shaft 702, and the pressing column 701 is perpendicular to the supporting shaft 702. The design of the cylinder is beneficial to the up-and-down movement of the compression column 701. The pressing column 701 is arranged in the middle of the reversing separation mechanism 7, the two top columns 704 are symmetrically arranged on the side edges of the reversing separation mechanism 7 by taking the pressing column 701 as a center, the pressing column 701 and the top columns 704 penetrate through the socket shell, and when a plug and the socket are separated and the plug is completely inserted into the socket, the upper surfaces of the pressing column 701 and the top columns 704 are flush with the upper surface of the socket shell. The support shaft 702 is arranged at the lower end of the pressing column 701 and is fixedly connected with the pressing column 701, one end of the support arm 703 is hinged with the support shaft 702, the middle of the support arm is movably connected with the socket shell, and the other end of the support arm is hinged with the top column 704. When the pressing column 701 is forced to move downwards, the supporting shaft 702 moves downwards along with the pressing column 701, the end of the supporting arm 703 connected with the pressing column 701 moves downwards, and the end of the supporting arm 703 connected with the top column 704 moves upwards under the reversing action of the middle part and the socket shell. Namely, the pressing column 701, the supporting arm 703, the top column 704 and the socket shell form a planar reversing mechanism, the downward acting force of the button 1 is converted into the upward acting force of the top column 704, and meanwhile, the plurality of top columns 704 share the downward acting force of the button 1 together, so that the effects of saving labor and improving the bearing capacity of the reversing separation mechanism 7 can be achieved.

The lower end of the button 1 is electrically connected with the upper end of the press column 701, the upper end of the button 1 is an insulator, the button 1 is electrically connected with the pin 601, the press column 701 is electrically connected with the jack 602, and the plug and the socket are required to be used in a set. If the plug is fully inserted into the socket and the button 1 is not in contact with the pressing column 701, the plug cannot obtain power from the socket, and the socket cannot generate current, so that electric shock and electric leakage are prevented. Therefore, the anti-theft function of the plug and the socket can be achieved. Meanwhile, the plug of the plug connector can prevent the wrong insertion of the socket, and is a fool-proof mechanism. For special type equipment, the wrong power socket is used, and the power supply cannot be connected, so that power supply accidents are caused.

When the plug needs to be separated from the socket, the button 1 is pressed, the button 1 extrudes the reversing separating mechanism 7, the reversing separating mechanism 7 transmits force to the socket, the button 1 transmits the force to the plug, the reversing separating mechanism 7 is of a labor-saving structure, the plug and the socket can be separated easily, and the reversing separating mechanism 7 is compact in layout and small in occupied space.

In an embodiment of the present application, the support arm 703 further includes a connecting shaft 705, in this embodiment, the connecting shaft 705 is integrally disposed with the support arm 703, and two sides of the middle of the support arm 703 protrude as the connecting shaft 705 to be movably connected with the socket housing, so that the support arm 703 and the socket housing can rotate relatively, and at the same time, the direction of the ground force applied to the compression leg 701 is converted. The contact surfaces of the support arms 703, the movable joints of the support shafts and the top posts are arc surfaces, the arc surfaces wrap the lower ends of the support shafts 702 or the top posts 704, and the arc surfaces are designed to facilitate rotation after hinging, so that mutual abrasion among the movable contact surfaces of the reversing separation mechanism 7 is reduced. The cambered surface also absorbs horizontal displacement generated in the rotation process, and ensures that the compression leg 701 and the top leg 704 only move in the vertical direction. The connecting shaft 705 and the supporting arm 703 are designed into a whole, so that the processing difficulty of the supporting arm 703 can be reduced, and the cost is reduced. In other embodiments, a through hole may be formed in the middle of the support arm 703 and the connection shaft 705 may be inserted through the through hole, and the connection shaft 705 protrudes from both ends of the through hole to movably connect the support arm 703 and the socket housing. The design of the connecting shaft 705 separately from the support arm 703 can increase the mobility and the service life of the support arm 703, and the actual design condition is subject to requirements. The connecting shaft 705 ensures that the supporting arm 703 can only rotate relative to the socket and cannot move in the horizontal or vertical direction, and plays a role in fixing the direction of the force of the reversing and separating mechanism 7 and the switching button 1.

The supporting arms 703 are used pairwise and are arranged in a back direction, one of the paired supporting arms 703 has an arc surface with the contact end of the supporting shaft, the other supporting arm has two arc surfaces with the contact end of the supporting shaft, the lower end of the arc surfaces is provided with a strip-shaped convex rib 707 parallel to the arc, a T-shaped opening A is arranged between the arc surfaces of the supporting arms 703 with the two arc surfaces, and the arc surfaces of the supporting arms 703 with one arc surface are crossed with the arc surfaces and movably connected in the opening A. Therefore, each pair of supporting arms 703 can be inserted into each other, can rotate mutually and cannot move left and right, so that the limiting effect is achieved, and the reversing separation mechanism 7 is more stable.

The lower end of the top column 704 is a horizontal cylinder matched with the arc surface of the supporting arm 703, the upper end of the top column 704 is a hemisphere and upwards pushes up the plug shell in a spherical form, so that the plug pin 601 and the jack 602 are separated favorably, the middle end of the top column is a vertical cylinder, a spring 706 is sleeved on the vertical cylinder between the horizontal cylinder and the socket shell, and a gasket 708 is arranged between the horizontal cylinder and the spring 706. The vertical cylinder is arranged to facilitate the up-and-down movement of the top pillar 704 and facilitate the sleeving of the spring 706, and the horizontal cylinder facilitates the mutual rotation of the top pillar 704 and the supporting arm 703, increases the stress area, and reduces the bearing capacity of the top pillar 704. When the plug is plugged into the socket, the top column 704 is supported by the spring 706 due to the action of the spring 706 and does not move up and down, when the plug needs to be pulled out of the socket, the spring 706 is compressed, the top column 704 moves up, and when the plug is pulled out of the socket, the pressing force is removed, and the top column 704 is stretched to the original position by the spring 706.

When the button 1 is pressed to be in the same plane as the upper surface of the plug housing, the pins 601 are completely disengaged from the receptacles 602 and the reset element 2 is completely compressed. The cross section of the cylinder A is equal to one square centimeter (the area of the thumb nail of an adult) so as to be convenient for pressing, meanwhile, the larger the cross section area is, the smaller the force-bearing area is, the smaller the force which needs to be exerted when an operator presses the button is, but the larger the corresponding requirement on the internal activity space of the plug and the socket is.

The contact surface of the pressing column 701 and the button 1 is designed into a spherical surface, so that the respective bearing capacity of the reversing separation mechanism 7 and the button 1 is enhanced, the stress area is increased in a phase-changing manner, the spherical surface can rotate relatively, the mutual friction between the button 1 and a plug shell is reduced, and the service life of the button 1 is prolonged. If the plug is inserted into a non-matching socket, the ball body at the lower end of the column C103 will abut against the upper surface of the socket, so that the plug cannot be completely inserted into the socket, and the plug cannot be electrically connected with the socket. If a non-matching plug is plugged into a socket, the press stud 701 cannot be electrically connected with the plug, and the non-matching plug cannot obtain power from the socket.

The sealing elastomer material is a styrene elastomer. The sealing elastic material forms a long seam around the through hole I10, a hollow chamber is arranged below the sealing elastic material, and the sealing elastic material can be extruded downwards. When the plug and the socket are separated, the through hole I10 is sealed due to the elastic action of the styrene elastomer, so that liquid is prevented from entering the socket; when the plug is inserted into the socket, the pin 601 can easily pass through the through hole I10 from the slit because the styrene elastomer is a soft solid with elasticity. Meanwhile, the styrene elastomer has high temperature resistance and wear resistance and can effectively deal with electric sparks which are often generated at the position of the through hole I10. The through holes I are matched with the pins for use. The through hole I10 is matched with the pin 601, and the lower end of the through hole I10 is away from the upper end of the pole piece 603 by a certain distance, so that the connection between the pin 601 and the jack 602 is not hindered.

The outer surfaces of the side wall of the cylinder C103 at the lower end of the button 1, the side wall of the compression leg 701 and the side wall of the top leg 704 are all adhered with a layer of sealing elastic material, namely styrene elastomer. The styrene elastomer seals the movable connection part of the button 1 and the ejection structure 7, but cannot be blocked, so that electric leakage and electric shock are prevented. Therefore, liquid can not enter the plug and the socket from the movable connection part of the button 1 and the ejection structure 7, the wear resistance of the button 1 and the ejection structure 7 can be enhanced, and the movement of the button 1 and the ejection structure 7 can not be influenced.
