A connecting ring 302 is also provided on the outside of the connecting block 305. Specifically, during use, the rotating ring 301 is moved relative to the fixed column 201 to drive the connecting ring 302 to slide inside the sliding groove 205. The sliding connecting ring 302 drives the adjusting member 6 to control the fixing member 5 to clamp the center sleeve. The rotating ring 301 and the fixed column 201 are connected by threads. The connection enables the rotating ring 301 to move linearly along the fixed column 201. The annular groove 306 is in a circular ring shape. When the rotating ring 301 moves, the cooperation between the annular groove 306 and the connecting block 305 drives the connecting ring 302 to slide inside the sliding groove 205, so that the connecting ring 302 can control the adjustment member 6 to move in position. The cooperation between the annular groove 306 and the connecting block 305 allows the connecting ring 302 to move with the rotating ring 301 while ensuring that the connecting ring 302 can rotate relative to the rotating ring 301. The guide hole 206 can guide the connecting block 305 during use to ensure that the connecting ring 302 can stably slide inside the sliding groove 205.

The connecting ring 302 and the through hole 304 can be connected by a mounting ring or a bolt, so that the sliding ring 602 can move synchronously with the connecting ring 302. The sliding block 601 is provided with a rotation groove relative to the side of the sliding ring 602. The bottom of the sliding ring 602 is provided with a mounting ring. The mounting ring has the same shape as the connecting groove. The mounting ring can be T-shaped or dovetail-shaped to ensure that the sliding block 601 and the sliding ring 602 can be stably connected during use.

[0043] like Figures 1 to 14As shown, the fixing member 5 includes a plurality of guide columns 501, which are connected to the fixed column 201, and the guide columns 501 correspond to the sliding blocks 601 one by one. A sliding column 503 is slidably connected to one end of the guide column 501, and a sliding rod 502 is provided at the end of the sliding column 503 relative to the sliding block 601, and the sliding rod 502 passes through the guide column 501 and the fixed column 201, and the sliding rod 502 slides inside the wedge-shaped groove 603, and a slot 507 is provided at the other end of the sliding column 503, and a connecting rod 504 and a supporting block 505 are sequentially provided inside the slot 507. Specifically, during the sliding process of the sliding block 601, the sliding sliding block 601 cooperates with the wedge-shaped groove 603 to push the sliding rod 502 to move linearly along the guide column 501, and the linearly moving sliding rod 502 controls the sliding column 503 and the support block 505 clamp the center sleeve, the guide column 501 and the fixed column 201 can be connected by bolts or snaps, so that the guide column 501 can be quickly replaced according to the center sleeves of different sizes. The guide column 501 can guide the moving direction of the sliding column 503 during use to ensure that the sliding column 503 can stably clamp the center sleeve during use. The length of the connecting rod 504 can be replaced according to the size of the center sleeve. The slot 507 has the same shape as the connecting rod 504, so that the connecting rod 504 can be stably inserted into the slot 507 during use. The connecting rod 504 and the sliding column 503 can be connected by bolts or pins to ensure the stability of the connecting rod 504 and the sliding column 503 during the connection process.

To accommodate, avoid the spring 303 from interfering with the connecting ring 302 during the compression process. When the fixed column 201 rotates, the support block 505, the sliding column 503 and the guide column 501 will move outward under the action of centrifugal force. The moving support block 505 can further clamp the center sleeve. When the sliding rod 502 is separated from the sliding block 601, the spring 303 can provide thrust to the fixed ring 604, so that the sliding block 601 can slide inside the guide groove 202, thereby limiting the sliding rod 502 after the moving position, and further ensuring that the support block 505 can stably clamp the center sleeve.
