As shown in fig. 6, 11 and 12, the tension assembly 54 includes a tension spring 541 perpendicular to the first direction, one end of the tension spring 541 is slidably fitted with the third link 523, and the other end is fixedly connected to the support plate 422.

Specifically, the tensioning assembly 54 further includes a locking device 542 fixedly connected to the support plate 422 and slidably engaged with the third link 523, a sliding block 543 slidably engaged with the third link 523, a tightening device 544 rotatably mounted at a distal end of the locking device 542, and a tightening screw 545 threadedly engaged with the locking device 544, wherein the tension spring 541 is fixedly connected between the sliding block 543 and the tightening screw 545.

More specifically, the stopper 542 has a U-shaped structure, and includes two stopper plates 5421 parallel to each other and perpendicular to the third link 523, and a connecting plate 5422 connected between the two stopper plates 5421. The two limiting plates 5421 are provided with sliding grooves 5423 which penetrate along the first direction and extend along the second direction, and the third connecting rod 523 penetrates through the sliding grooves 5423; a first assembly hole (not shown) is formed in the slider 543 along the first direction, the third link 523 is inserted into the first assembly hole, so that the slider 543 is slidably mounted on the third link 523, and the slider 543, the tension spring 541 and the tightening screw 545 are located between the two limiting plates 5421 of the locking device 542. The slider 543 is larger in size than the width of the slide groove 5423 of the stopper plate 5421, and therefore the slider 543 is held between the two stopper plates 5421.

The coupling plate 5422 of the locking device 542 is provided with a second assembling hole (not shown) penetrating in the second direction, through which the tightening device 544 passes to couple with the tightening screw 545.

Moreover, when the present invention is in a steady state, the screwing amount of the tightening screw 545 screwed into the screwing device 544 can be changed by rotating the screwing device 544, so as to adjust the bistable unstable-state jumping force of the traverse braking mechanism 5, i.e. the external force applied for switching the two steady states of the present invention can be adjusted, the larger the adjustment of the tightening force of the tension spring 541 is, the more stable the steady state is, the larger the external force needs to be applied in the braking state to release the braking state, thereby achieving the effect of adjusting the braking force, and after the braking member is worn, the friction force between the braking member and the rubbed plate can be adjusted by adjusting the pulling force of the tension spring, thereby ensuring the braking effect.

Because the detent 542 is fixedly connected with the support plate 423, in the moving process of the connecting rod assembly 52, the slider 543 can only move in the second direction within the range limited by the two limiting plates 5421, so that the tension spring 541 is always perpendicular to the first direction, and the third connecting rod 523 is always parallel to the first direction, so that a parallelogram is always formed among the connecting lines of the first connecting rod 521, the second connecting rod 522, the third connecting rod 523, the driving shaft 512 and the driven shaft 531.

Furthermore, the detent 542 of the present invention may also adopt a different scheme that a sliding groove perpendicular to the third link 523 is formed in the detent 542, the width of the sliding groove is the same as the width of the slider 543, the slider 543 is slidably disposed in the sliding groove, the slider 543 can only move in the sliding groove in the direction perpendicular to the third link 523, and the other end of the spring 541 is further mounted by the matching connection of the screw 544 penetrating the second assembly hole of the connecting plate 5422 and the tightening screw 545.

Furthermore, the link assembly 52 further includes two transfer limiting heads 524, one end of each of the two transfer limiting heads 524 is respectively mounted to two ends of the third link 523 in a threaded manner, the other end of each of the two transfer limiting heads 524 is respectively hinged to the first link 521 and the third link 521 in a pivot pin hinged manner, and the size of the transfer limiting head 524 is larger than the width of the sliding slot 5423 of the limiting plate 5421, so that the limiting plate 5421 does not go over the transfer limiting head 524 and can play a role in limiting the rotation angle of the first link 521 and the second link 522.

In the embodiment disclosed in the present invention, the first link 521, the second link 522 and the third link 523 are hinged together by a shaft pin.

In the embodiment of the present disclosure, two sets of tensioning assemblies 54 are provided and symmetrically disposed on two sides of the perpendicular bisector of the connection line between the driving shaft 512 and the driven shaft 531, and the forces of the tension springs 541 of the two sets of tensioning assemblies 54 may be the same or different. In other embodiments, the number of the tension assemblies 54 may be set to 1, in which case the tension assemblies 54 are disposed on a midperpendicular of a line connecting the driving shaft 512 and the driven shaft 531.

In other embodiments, the traverse motion assembly 42 may be designed to be fixed, i.e., the traverse motion assembly 42 is fixedly mounted on the swing mechanism 2, and the traverse fixing assembly 41 is movably mounted in the traverse motion assembly 42, and the braking therebetween is realized by the traverse braking mechanism 5.

According to the invention, the driving assembly 51 drives the connecting rod assembly 52 to move, so that the braking assembly 53 is driven to move, the braking part 534 of the braking assembly 53 is in close contact with or separated from the upper surface of the braking plate 413 of the traverse fixing assembly 41, and braking or unlocking is realized. Specifically, the knob 511 of the transverse moving brake mechanism 5 is rotated to drive the driving shaft 512 to rotate, the driving shaft 512 rotates to drive the first link 521 to rotate, the first link 521 rotates to drive the third link 523 to move along the first direction, the third link 523 moves to drive the second link 522 to rotate, the second link 522 rotates to drive the driven shaft 531 to rotate, the driven shaft 531 rotates to drive the cam 532 to rotate, the cam 532 rotates to enable the pressing block 533 to move axially along the track defined by the guide post 552, and finally the brake component 534 on the pressing block 533 is in close contact with the brake plate 413 to generate friction force to brake or the brake component 534 is separated from the brake plate 413 to unlock.

In this process, the traverse brake mechanism 5 moves from the non-braking state to the bistable unstable state and then to the braking state.

Specifically, referring to FIGS. 13-15, when the traverse brake mechanism 5 is in the non-braking state, the knob 511 is in the first position, the brake 534 is in non-contact with the brake plate 413, and the traverse motion assembly 42 is movable laterally relative to the traverse fixing assembly 41. Referring to fig. 1313, the switching stopper 524 contacts the detent 542 to prevent the link assembly 52 from further rotating, and the tension spring 541 is at a position with minimum tension, which is in a stable state.

Referring to fig. 16, the traverse brake mechanism 5 is in an unstable state, in which the first link 521 and the second link 522 are perpendicular to the first direction, the distance between the third link 523 and the connecting line between the driving shaft 512 and the driven shaft 531 is maximized, the length of the tension spring 541 is maximized, and the tension value is maximized, so that the state is unstable.

Referring to FIGS. 17-19, when the traverse brake mechanism 5 is in a braking state, the knob 511 is in a second position, the stopper 534 is in pressing contact with the stopper 413, and the traverse motion assembly 42 cannot move relative to the traverse fixing assembly 41, thereby achieving the purpose of braking. As shown in fig. 15, the switching stopper 524 of the other end of the third link 523 contacts with the stopper 542 to prevent the link assembly 52 from rotating further, and the tension spring 541 has now passed the maximum tension position (bistable unstable position) and is in the minimum tension position, which is in the stable state.
