To ensure that the flexible drive 4545 is able to always transmit power from the first drive roller 4543 to the second drive roller 4544, the flexible drive 4545 may be a chain or the like.

Specifically, cable locking assembly 455 includes a pull rod 4551, a locking spring 4552, and a latch block 4553. The latch block 4553 is arranged in the connecting seat 44 and can be clamped with the teeth of the first gear 452, and one end of the pull rod 4551 penetrates into the connecting seat 44; one end of a locking elastic piece 4552 is fixed on the pull rod 4551, and the other end is connected with a latch block 4553; pressing the lever 4551 can engage the latch block 4553 with the teeth of the first gear 452.

When the cable support assembly 454 needs to be fixed, the pull rod 4551 is pressed down, the pull rod 4551 moves towards the direction close to the first gear 452, at this time, the locking elastic member 4552 compresses and generates resilience force, and the latch block 4553 is engaged with the teeth of the first gear 452 under the action of the resilience force, so that the rotation of the first gear 452 is avoided. When the position of the cable 100 needs to be adjusted, the pull rod 4551 is pulled out in a direction away from the first gear 452, the locking elastic member 4552 returns to the free length, and the latch block 4553 is away from the first gear 452, so that the worker rotates the first gear 452 by rotating the rocking handle 451 to adjust the position of the cable support assembly 454.

In this embodiment, to further adjust the position of the cable 100, the cable fixing mechanism 46 is mounted on the cable support assembly 454 in an adjustable position, as shown in fig. 6.

Specifically, the cable fixing mechanism 46 includes a telescopic support frame 461, a slide is disposed on the upper support frame 4542, the telescopic support frame 461 is fixed in the slide in a penetrating manner, and an installation position of the telescopic support frame 461 in the slide is adjustable along the slide.

As shown in fig. 8, to fix the cable 100, the cable fixing mechanism 46 further includes a cable catch 462, a cover plate 463, a rubber top block 464, and a threaded fastener 465.
