[0035] When the staff needs to climb a high place such as an electric tower to perform aerial work, first put the safety rope into the inner wall of the rope ring 14. When reaching a high place and needing to slide and hang quickly, first hang the hook 13 into the safety ring of the electric tower, then push the clamping plate push-pull block 31 to move to the left and drive the slider plate 33 and the locking clamping plate 34 at the bottom to move to the left so that the locking clamping plate 34 is stuck in the inner wall of the hook 13, and the electric tower safety ring is put on the inner side of the locking clamping plate 34 and the hook 13. When the locking clamping plate 34 is completely stuck in the hook 13, the pressure rod 39 on the inner wall of the slider plate 33 is aligned with the slot 211 opened in the rotating disk 26, and then the pressure plate pressure rod 38 is pressed to drive the pressure rod 39 to slide downward so that the bottom of the pressure rod 39 is stuck in the inner wall of the slot 211 opened in the two rotating disks 26, and then the push block 110 is pushed to drive the push rod 17 to push the push-pull vertical plate 218 to move to the left, and the movement of the push-pull vertical plate 218 drives the push-pull rod 215, the hinge rod slider 213 and the hinge rod 212 to move to the left. When the hinge rod 212 moves to the left, it pushes the two rotating rods 214 to rotate and change the angle. The two rotating rods 214 rotate and change the angle, thereby pushing the two pull blocks 27 to drive the turntable 26 to rotate. The two turntables 26 rotate so that the two sets of positioning blocks 210 slide on the inner wall of the arc-shaped slide groove 28 through the positioning block slide rod 29, so that the two sets of positioning blocks 210 move inward and are stuck in the inner wall of the multiple positioning locking grooves 310 opened on the outer wall of the pressure rod 39, thereby limiting the clamping mechanism 3 , so that the limit lock clamp plate 34 is always stuck in the inner wall of the hook 13, and when the two sets of positioning blocks 210 are completely stuck in the inner wall of the positioning locking groove 310, the block 112 on one side of the connecting block 111 and the limit block 113 at the top and bottom thereof are just completely stuck in the inner wall of the limit groove 19 opened by the limit block 18 and the top and bottom, thereby ensuring that the hinge rod 212 will not move, preventing the hook 13 from being separated from the lock clamp plate 34, so that the staff can maintain stability when working in the air;

[0036] At the same time, when the hinged rod 212 moves to the left for limiting, the safety rope locking hook connecting rod 216 fixed on the right side pulls the safety rope locking hook 217 to slide, and the safety rope locking hook 217 slides on the inner wall of the rope threading ring 14 to fix the safety rope on the inner wall of the rope threading ring 14, thereby strengthening the stable connection between the safety rope and the overall device.

[0037] See also Fig.10The wristband control mechanism 4 includes a wristband control block 41, the rear side of the wristband control block 41 is fixedly connected to the right side of the rear side of the outer wall of the rope threading ring 14, the top of the left side of the inner wall of the wristband control block 41 is rotatably connected with a retractable roller rotating rod 42, the outer wall of the retractable roller rotating rod 42 is fixedly connected with a retractable roller 43, the outer wall of the retractable roller 43 is sleeved with a wristband belt 45, the wristband belt 45 extends from the side away from the retractable roller 43 to the outer wall of the wristband control block 41 and is fixedly connected to the bottom of the wristband control block 41, the right end of the retractable roller rotating rod 42 extends to the outer wall of the wristband control block 41 and is fixedly connected with a retractable roller rotating disk 44;

[0038] When performing aerial operations, in order to prevent the worker's hand from slipping and causing the entire device to fall off, the wrist strap 45 is sleeved on the outer wall of the retracting roller 43 to realize the rotation control of the retracting roller rotating rod 42. When the worker needs to tighten the wrist strap 45, it can be achieved by rotating the retracting roller turntable 44. The rotation of the retracting roller turntable 44 drives the retracting roller rotating rod 42 to rotate, and then rotates the retracting roller 43, thereby tightening the wrist strap 45. Conversely, if the wrist strap 45 needs to be loosened, the retracting roller turntable 44 can be reversed to rotate the retracting roller rotating rod 42 in the opposite direction, thereby loosening the wrist strap 45. When the wrist strap 45 is relaxed to a suitable dimension, the worker puts his wrist on the inner side of the wrist strap 45.

[0039] Working principle: When the staff needs to climb the power tower and other high places to perform aerial work, first put the safety rope into the inner wall of the rope ring 14. When reaching the high place and needing to slide and hang quickly, first hang the hook 13 into the safety ring of the power tower, then push the clamping plate push-pull block 31 to move to the left and drive the slider plate 33 and the locking clamping plate 34 at the bottom to move to the left so that the locking clamping plate 34 is stuck in the inner wall of the hook 13, and put the power tower safety ring on the inner side of the locking clamping plate 34 and the hook 13. When the locking clamping plate 34 is completely stuck in the inner wall of the hook 13, the pressure rod 39 on the inner wall of the slider plate 33 is aligned with the turntable 2 6, and then the pressure plate pressure rod 38 is pressed to drive the pressure rod 39 to slide downward so that the bottom of the pressure rod 39 is stuck in the inner wall of the slot 211 opened by the two rotating disks 26, and then the push block 110 is pushed to drive the push rod 17 to push the push-pull vertical plate 218 to move to the left, and the push-pull vertical plate 218 moves to drive the push-pull rod 215, the hinge rod slider 213 and the hinge rod 212 to move to the left. When the hinge rod 212 moves to the left, it pushes the two rotating rods 214 to rotate and change the angle. The two rotating rods 214 rotate to change the angle to push the two pull blocks 27 drives the turntable 26 to rotate, and the two turntables 26 rotate so that the two groups of positioning blocks 210 slide on the inner wall of the arc-shaped slide groove 28 through the positioning block slide rod 29, so that the two groups of positioning blocks 210 move inward and snap into the inner walls of the multiple positioning locking grooves 310 opened on the outer wall of the pressure rod 39, thereby limiting the clamping plate mechanism 3, so that the limiting locking clamping plate 34 is always snapped into the inner wall of the hook 13, and when the two groups of positioning blocks 210 are completely snapped into the inner wall of the positioning locking groove 310, the block 112 on one side of the connecting block 111 and the limiting block 113 at the top and bottom thereof are just completely The limit block 18 is inserted into the inner wall of the limit groove 19 opened at the top and the bottom, thereby ensuring that the hinged rod 212 will not move, preventing the hook 13 from being separated from the locking clamp plate 34, so that the staff can maintain stability when working in the air. At the same time, when the hinged rod 212 moves to the left for limiting, the safety rope locking hook connecting rod 216 fixed on the right side pulls the safety rope locking hook 217 to slide, and the safety rope locking hook 217 slides on the inner wall of the rope threading ring 14 to fix the safety rope on the inner wall of the rope threading ring 14, thereby reinforcing the stable connection between the safety rope and the device as a whole;

[0040] When performing aerial operations, in order to prevent the worker's hand from slipping and causing the entire device to fall off, the wrist strap 45 is sleeved on the outer wall of the retracting roller 43 to realize the rotation control of the retracting roller rotating rod 42. When the worker needs to tighten the wrist strap 45, it can be achieved by rotating the retracting roller turntable 44. The rotation of the retracting roller turntable 44 drives the retracting roller rotating rod 42 to rotate, and then rotates the retracting roller 43, thereby tightening the wrist strap 45. Conversely, if the wrist strap 45 needs to be loosened, the retracting roller turntable 44 can be reversed to rotate the retracting roller rotating rod 42 in the opposite direction, thereby loosening the wrist strap 45.
