[0029] Embodiment 2: On the basis of Embodiment 1, a motor 6 is fixed on the surface of the bottom plate 1. A gear 5 is connected to the end of the motor 6. The motor 6 can drive the gear 5 to rotate. Teeth 14 are arranged on the surface of the rotating shaft 3. The teeth on the surface of the gear 5 are meshed with the teeth 14. The rotating shaft 3 rotates with the gear 5. A fixed rod 22 is fixed on the surface of the rotating shaft 3. An arc rod 21 is fixed on the surface of the fixed rod 22. A second telescopic rod 20 is inserted into the arc rod 21. The second telescopic rod 20 can move inside the arc rod 21. A spring is arranged inside the arc rod 21. The spring connects the inside of the arc rod 21 and the end of the second telescopic rod 20. The spring has a thrust on the second telescopic rod 20, so that the second telescopic rod 20 extends out of the arc rod 21. A pressure sensor 19 is fixed at the end of the second telescopic rod 20. The pressure sensor 19 moves with the second telescopic rod 20. The holding block 17 moves. After the holding block 17 moves, it holds against the surface of the pressure sensor 19. The pressure sensor 19 is squeezed, so that the second telescopic rod 20 is inserted into the arc rod 21. The pressure sensor 19 can sense being squeezed.

[0030] Multiple groups of fixing rings 12 are fixed on the surface of the rope 4. Two extension rods 11 are fixed on the surface of the fixing ring 12. A first telescopic rod 10 is inserted into the extension rod 11. A spring is arranged inside the extension rod 11. The spring connects the inside of the extension rod 11 and the end of the first telescopic rod 10. A first ring groove 9 is formed on the surface of the rotating shaft 3. The first telescopic rod 10 is inserted into the first ring groove 9. A plugging rod 16 is inserted into the first ring groove 9. The plugging rod 16 can move in the first ring groove 9. A spring 18 is connected to the surface of the plugging rod 16. The spring 18 is located in the first ring groove 9. The other end of the spring 18 is connected to the surface of the fixed rod 22. The bottom of the rope 4 is connected with a hook, and the hook is fixed. The diameter of the extension ring 7 on the surface of the rope 4 is larger than the inner diameter of the holding ring 15. After the rope 4 moves, the extension ring 7 moves with the rope 4. After the extension ring 7 moves, it holds against the surface of the holding ring 15. When the hook at the top of the rope 4 falls off, after the rope 4 slides, the extension ring 7 on the surface of the rope 4 holds against the surface of the holding ring 15, which can also play a role in preventing the rope 4 from sliding continuously.

[0031] The first telescopic rod 10 can move in the first ring groove 9. The spring inside the extension rod 11 has a thrust on the first telescopic rod 10, so that the first telescopic rod 10 extends out of the extension rod 11. After the holding block 17 rotates with the rotating shaft 3, it holds against the surface of the extension rod 11. After the holding block 17 moves, it holds against the surface of the pressure sensor 19. The holding block 17 rotates with the rotating shaft 3. The holding block 17 holds against the surface of the extension rod 11, so that the plugging rod 16 squeezes the spring 18. The holding block 17 moves. After the holding block 17 moves, it holds against the surface of the pressure sensor 19. The pressure sensor 19 is squeezed.

[0032] The top of the rope 4 is fixed by a hook. The rope 4 is wound around the surface of the rotating shaft 3. A second annular groove 13 is formed on the surface of the rotating shaft 3. The rope 4 is wound in the second annular groove 13, and the rope 4 passes through the inside of the holding ring 15. A fixing ring 12 is fixed on the surface of the rope 4. A first telescopic rod 10 is inserted into the extension rod 11 on the surface of the fixing ring 12. A spring is arranged inside the extension rod 11. The first telescopic rod 10 is inserted into the first annular groove 9. The gear 5 is driven to rotate by the motor 6. The teeth on the surface of the gear 5 are engaged with the teeth 14. The rotating shaft 3 rotates with the gear 5. The holding block 17 rotates with the rotating shaft 3. The holding block 17 abuts against the surface of the extension rod 11, so that the insertion rod 16 compresses the spring 18, and the holding block 17 moves. After the holding block 17 moves, it abuts against the surface of the pressure sensor 19. The pressure sensor 19 is squeezed, so that the second telescopic rod 20 is inserted into the arc-shaped rod 21. If the pressure sensor 19 can sense being squeezed, it means that the hook at the top of the rope 4 is stable. When the hook at the top of the rope 4 falls off, the rope 4 slides, and the extension ring 7 on the surface of the rope 4 abuts against the surface of the holding ring 15, which can also prevent the rope 4 from sliding further.
