As shown in fig. 15, the winding mechanism 423 includes a hole site disk 4231, a second bearing 4232, a one-way bearing 4233, a wire spool 4234, an index pin 4235 and a one-way damper 4236, the hole site disk 4231 is disposed in the suspension tube 422, a connecting shaft 42311 is disposed in the center of the hole site disk 4231 in a penetrating manner in the axial direction, the one-way damper 4236 is fixedly sleeved on one side connecting shaft 42311 of the hole site disk 4231, the second bearing 4232 and the one-way bearing 4233 are sequentially fixedly sleeved on the other side connecting shaft 42311 of the hole site disk 4231, the wire spool 4234 is connected with the one-way bearing 4233, the hole site disk 4231 is disposed in the suspension tube 422 and is rotatably connected with the suspension tube 422 through the one-way damper 4236, and when the index pin 4235 is disposed in the suspension tube 422 and is matched with the hole site disk 4231 to lock the hole site disk 4231, the second bearing 4232 is fixed, and the wire spool 4234 is unidirectionally rotated through the one-way bearing 4233.

In this embodiment, when the hole position disc 4231 is locked by the index pin 4235, the hole position disc 4231 and the second bearing 4232 are both non-rotatable, the wire spool 4234 can rotate unidirectionally through the unidirectional bearing 4233, so that the wire spool 4234 can only rotate unidirectionally in the direction of shortening the rope, after the hole position disc 4231 is unlocked, the second bearing 4232 can rotate bidirectionally, the wire spool 4234 can rotate reversely to release the elastic rope, in addition, by arranging the unidirectional damper 4236, the unidirectional damper 4236 can rotate smoothly in one direction, and when rotating reversely, rotational resistance exists, and when rotating in the opposite direction, the unidirectional damper 4236 can be set to rotate in the direction of retracting the rope, no effort is required, and when rotating in the direction of releasing the rope, damping exists.

The foregoing is merely a preferred embodiment of the invention, which can be freely combined, and it should be pointed out that modifications and adaptations to those skilled in the art can be made without departing from the principles of the invention, which modifications and adaptations are also considered as protective scope of the invention.
