[0024] With reference to Figure 4As shown in the embodiment: the push block 9 is fixedly connected with a force storage spring 16 away from one side of the arc-shaped block 6, and the force storage spring 16 is fixedly connected with the inside of the adjusting hole 8 away from one side of the push block 9. When the staff pushes the push block 9 to push the insertion rod 10, the insertion rod 10 extrudes the force storage spring 16 to compress the force, and drives the insertion rod 10 to be inserted into the insertion hole 13 to be fixed. When the staff cancels the contact between the push block 9 and the arc-shaped block 6, the insertion rod 10 is quickly pushed under the action of the elastic force of the force storage spring 16, and drives the insertion rod 10 to be released from the limiting between the insertion hole 13, so as to release the hook 2 after the staff works.
[0025] Referring to Figure 4 As shown in the embodiment: the two ends of the adjusting block 4 are provided with threaded rods 17, and the two ends of the rotating column 7 are provided with threaded grooves 18. After the staff inserts the lock column 12 into the rotating column 7 and fixes it, the staff inserts the threaded rod 17 into the threaded groove 18 to fix the position of the rotating column 7, so that the rotating column 7 does not rotate in the control groove 5 during operation, and the contact between the push block 9 and the arc-shaped block 6 is unstable, which causes the limiting to fail.
[0026] Referring to Figure 5 As shown in the embodiment: the inside of the contraction groove 11 is provided with guide grooves 19 on both sides, and the lock column 12 is fixedly connected with guide blocks 20 on both sides. The surface of the guide block 20 is in sliding connection with the inside of the guide groove 19. When the staff moves the lock column 12, the lock column 12 drives the guide block 20 to slide in the guide groove 19. Through the above setting, the lock column 12 can be more stable during movement, avoiding the deviation of the lock column 12 during movement, and improving the stability of the whole.
[0027] Referring to Figure 4 As shown in the embodiment: the inside of the adjusting block 4 is provided with two ring grooves 22, and the outer diameter surface of the rotating column 7 is fixedly connected with two ring blocks 21.

Through the above setting, the rotating column 7 can be more stable during rotation, and is not easy to shake or deviate, improving the stability and use effect of the equipment. At the same time, the design that the ring block 21 rotates in the ring groove 22 also facilitates the positioning and adjustment of the rotating column 7, so that the operating personnel can more accurately control the rotation angle and position of the rotating column 7, further improving the operability and practicality of the equipment.
[0028] Working principle: the worker inserts the lock column 12 into the inside of the rotating column 7, and rotates the rotating column 7, so that the rotating column 7 drives the push block 9 and the insertion rod 10 to move, and the push block 9 contacts the arc block 6, when the push block 9 moves to the thicker side of the arc block 6, the arc block 6 gradually extrudes the push block 9 to drive the insertion rod 10 to insert into the insertion hole 13 for limiting and fixing, through the above setting, the hook 2 can be stably hooked on the fixed object, avoiding falling off, through the setting that the size of the insertion rod 10 is matched with the size of the insertion hole 13, the insertion rod 10 can be stably inserted into the inside of the insertion hole 13, so as to improve the stability and connection strength of the device, in the assembly process, the insertion rod 10 slides along the inner wall of the insertion hole 13 until it is completely inserted, forming a tight plug-in cooperation, when the worker moves the push block 9, the push block 9 drives the sliding block 15 to slide in the inside of the sliding groove 14, through the above setting, the push block 9 is more stable during movement, avoiding deviation or misplacement caused by shaking or external force, at the same time, the design that the sliding block 15 slides in the inside of the sliding groove 14 not only enhances the stability of the structure, but also ensures the smoothness and flexibility of the push block 9 during movement, when the worker pushes the push block 9 to drive the insertion rod 10, the insertion rod 10 extrudes the force storage spring 16 to compress the force storage, and drives the insertion rod 10 to insert into the insertion hole 13 for fixing, when the worker cancels the contact between the push block 9 and the arc block 6, the insertion rod 10 is quickly pushed under the action of the rebound force of the force storage spring 16, and drives the insertion rod 10 to release the limiting between the insertion hole 13, so as to release the hook 2 after the worker works, after the worker inserts the lock column 12 into the rotating column 7 and fixes it, the worker inserts the threaded rod 17 into the threaded groove 18 to fix the position of the rotating column 7, avoiding the rotating column 7 rotating in the inside of the control groove 5 during work, so that the contact between the push block 9 and the arc block 6 is unstable, causing the limiting to fail, when the worker moves the lock column 12, the lock column 12 drives the guide block 20 to slide in the inside of the guide groove 19, through the above setting, the lock column 12 can be more stable during movement, avoiding deviation during movement, improving the overall stability, when the worker rotates the rotating column 7, the rotating column 7 drives the ring block 21 to rotate in the inside of the ring groove 22, through the above setting, the rotating column 7 can be more stable during rotation, avoiding shaking or deviation, improving the stability and use effect of the equipment, at the same time, the design that the ring block 21 rotates in the inside of the ring groove 22 also facilitates the positioning and adjustment of the rotating column 7, so that the operator can more accurately control the rotation angle and position of the rotating column 7, further improving the operability and practicality of the equipment.
