The worker can control the extension length of the safety rope 1 from the inside of the protection box 2 through the limit mechanism 7. At the same time, when not in use, the rebound mechanism 6 can control the first rotating shaft 5 to rotate in the opposite direction. The first rotating shaft 5 rotates in the opposite direction while driving the gathering roller 4. The gathering roller 4 gathers the safety rope 1, so that the safety rope 1 enters the inside of the protection box 2 to protect the safety rope 1. The safety rope 1 can be stored and protected when the safety rope 1 is not in use, avoiding the safety belt from being placed on the ground, which causes the safety belt to wear. The safety of the safety belt during use is improved, and it can also avoid tripping the workers when it is placed on the ground.

[0028] like Figure 4As shown, the rebound mechanism 6 includes: a first clockwork spring 8 is arranged on the top outer surface of the first rotating shaft 5, one end of the first clockwork spring 8 is fixedly connected to the first rotating shaft 5; the other end of the first clockwork spring 8 is fixedly connected to the rebound box 9, and the rebound box 9 is fixedly connected to the protection box 2.

The safety rope 1 can be stored and protected when the safety rope 1 is not in use, avoiding the safety belt from being placed on the ground and causing wear of the safety belt, thereby improving the safety of the safety belt during use and avoiding tripping of workers when placed on the ground.

[0035] When in use, the staff presses the first rotating column 18, so that the first rotating column 18 rotates inside the first connecting buckle 16 through the third rotating shaft 17, and then buckles the first connecting buckle 16 on the building, loosens the first rotating column 18, and the first rotating column 18 is restored to be engaged with the first connecting buckle 16, which is convenient for the staff to connect the safety rope 1 with the building, and then presses the second rotating column 23, so that the second rotating column 23 rotates inside the second connecting buckle 21 with the fourth rotating shaft 22 as the center, and then buckles the second connecting buckle 21 on the body, loosens the second rotating column 23, and the second rotating column 23 rebounds and rotates with the fourth rotating shaft 22 as the center and engages with the second connecting buckle 21, which is convenient for the user to connect the device with himself, and finally pulls the movement of the ratchet 11 so that one side of the ratchet 11 The end rotates inside the travel groove 27 with the second rotating shaft 12 as the center of the circle, and the ratchet 11 separates from the ratchet 10 while rotating. The user can pull the safety rope 1 and then adjust the length of the safety rope 1 according to his or her needs. When the staff descends to a suitable height outside the building, the ratchet 11 is released, and the second spring 15 rebounds through the cooperation of the spring box 14. The second spring 15 drives the second rotating shaft 12 to rotate in the opposite direction, and the second rotating shaft 12 drives the ratchet 11, so that the ratchet 11 engages with the ratchet 10, and then the ratchet 10 is limited. The purpose of fixing the length of the safety rope 1 is achieved by limiting the ratchet 10. When the staff uses the safety belt, the length of the safety belt can be adjusted according to the staff's needs, thereby improving practicality.
