The transverse screw 9 drives the transverse offset seat 10 to move along the transverse circular rail 7 under the cooperation of the thread. After the transverse offset seat 10 moves to the set position, the longitudinal screw 13 is driven by the handle 16 to rotate along the second deflection bearing 12. The longitudinal screw 13 drives the lifting support 14 to move along the longitudinal circular rail 11 through the thread. After the lifting support 14 moves to the set position, the telescopic screw 15 is driven by the handle 16 to move along the telescopic threaded hole. The telescopic screw 15 drives the clamping component 2 to move, and the clamping component 2 moves After moving to the set position, the two groups of clamping arc plates 3 are driven to move toward each other through the clamping bolts and clamping nuts.
