[0019] Pull the pull ring 15, so that the pull ring 15 drives the support rod 12 to move. At this time, the first spring 16 and the second spring 17 are compressed. At this time, the support rod 12 drives the connecting plate 13 to move, and the connecting plate 13 drives the limiting tooth key 14 to separate from the gear 11;
[0020] Releasing the pull ring 15 releases the elastic force of the first spring 16 and the second spring 17, which pushes the connecting plate 13, so that the connecting plate 13 pushes the limiting tooth key 14 to engage with the gear 11, thereby limiting the gear 11.

[0026] When the worker climbs up the tower, he pulls the pull ring 15 each time he goes up a step, so that the pull ring 15 drives the support rod 12 to move. At this time, the first spring 16 and the second spring 17 are compressed. At this time, the support rod 12 drives the connecting plate 13 to move, and the connecting plate 13 drives the limiting tooth key 14 to separate from the gear 11, and pushes the slider 4, so that the slider 4 moves upward along the path of the slide groove 3, and the gear 11 moves and rotates along the path of the rack 8. At this time, the pull ring 15 is released, so that the first spring 16 and the second spring 17 release their elastic force, and the first spring 16 and the second spring 17 push the connecting plate 13, so that the connecting plate 13 pushes the limiting tooth key 14 to mesh with the gear 11, thereby limiting the gear 11, and thus limiting the slider 4, preventing the worker from falling when climbing.
