By setting two groups of limit blocks 7, the mounting block 6 is prevented from rotating inside the cylinder cavity 501. When the clamping block 8 is located inside the clamping groove 503, rotate the rotating ring 10. When the rotating ring 10 rotates outside the fixed cylinder 5, the two arc-shaped blocks 12 can be rotated and inserted into the two arc-shaped grooves 801, thereby fixing the mounting block 6 inside the cylinder cavity 501. By pulling the movable ring 14 to the right, the movable ring 14 slides on the outside of the rotating shaft 4, drives the telescopic rod 15 to extend and drives the limit rod 16 to move. When the limit rod 16 moves to the right, it drives the round block 17 to move, and when the round block 17 moves, it will compress the return spring 18, so that the left end of the limit rod 16 moves away from the limit hole 1001.
