When the reel 5 is pulled out, the reel 4 is driven by the reel 5 to rotate, so that the coil spring 7 is tightened, and at the same time, the ratchet 10 rotates so that the protrusion 8 on it snaps into the first slot 12 , while the block 9 slides on the first working surface 16 of one of the fixed blocks 14, as shown in FIG. 12 . When the reel 5 is finished or pulled to a certain position, loosen the handle ring 21 slightly, and then under the action of the elastic force of the coil spring 7, the reel 4 rotates toward the wire take-up direction until the clamping block 9 is in it. The first working surface 16 of a fixed block 14 slides into the third draw-in groove 15 of the fixed block 14 via the guide groove 18. At this moment, the user will hear a "click" sound, and the coiled wire 5 will no longer go further. Recycling, because the block 9 is stuck in the third slot 15 to limit the rotation of the winding reel 4, so the wire-out action is completed, as shown in Figure 13 . Then, when the user continues to pull the reel 5 forward, the ratchet 10 rotates with the reel 4, so that the block 9 comes out from the third slot 15, and is placed on the second working surface 17 of the fixed block 14. Slide to drive the ratchet 10 to rotate to the second slot 13, as shown in FIG. 14 . At this time, the winding reel 4 can rotate along the winding direction, so under the elastic force of the coil spring 7, the winding reel 4 is driven to rotate along the winding direction, and then the winding 5 is retracted. In this embodiment, three fixed blocks are provided (the number can be appropriately increased or decreased), which can realize the effect that the reel 5 can stop at any position when the reel 5 is pulled out, and when the reel 5 is pulled out, the reel 5 can be pulled forward. It is retracted into the winding reel 4, leaving only the handle ring 21 outside the shell 1.

When the winding reel 4 rotates along the winding direction, the rotating shaft 2 drives the first gear 22 to rotate, and then drives the second gear 23 to rotate, so that the rack 24 moves downward. When the rack 24 is descending, it will drive the hollow outer rod 25 to descend together and be retracted into the shell 1, and then drive the inner rod 29, the rotating rod 30 and the traction rope cover 31 to descend slowly, and the vertebral traction training ends.

The utility model is also provided with a placement groove on the shell 1. When the utility model is not in use, the rotating rod 30 is rotated to be parallel with the inner rod 29, and then the inner rod 29 is received in the hollow outer rod 25, and the hollow When the outer rod 25 is retracted into the housing 1, the rotating rod 30 and the traction rope sheath 31 at its end are also retracted into the placement groove together, so that the entire device appearance can be presented in the shape of a shell.
