[0016] The side end of the extrusion cam 10 is an inclined structure. The side end of the extrusion cam 10 abuts against the connecting wheel 9. The buffer spring 8 is sleeved on the connecting column 7. When the workpiece is initially clamped by the fixed clamping block 5 and the movable clamping block 6, the extrusion cam 10 rotates. The extrusion cam 10 squeezes the connecting wheel, thereby pushing the movable clamping block 6 to move. The moving distance of the movable clamping block 6 can be precisely controlled to avoid damage to the workpiece.
[0017] The lower end of the control member 19 is a hexagonal prism, the inner wall of the plug-in port 13 is a hexagonal structure, the middle of the control member 19 is a threaded column, and the upper end of the control member 19 is a handle. Now insert the lower end of the control member 19 into the plug-in port 13, and move the control member 19 downward until the middle of the control member 19 is threadedly connected to the second fixed block 18, and the rotating disk 11 and the extrusion cam 10 are driven to rotate by rotating the control member 19.

The engaging teeth 12 are engaged with the limiting teeth 15. A reset spring is fixedly connected between the side end of the limiting plate 14 and the inner wall of the cavity. When the rotating disk 11 rotates, the engaging teeth 12 squeeze the limiting teeth 15, thereby pushing the limiting plate 14 to rotate and compressing the reset spring to accumulate force until the limiting tooth 15 reaches the gap between the next engaging teeth 12. At this time, the reset spring drives the limiting plate 14 and the limiting teeth 15 to reset, thereby limiting and fixing the position of the rotating disk 11 to avoid movement of the clamping block 6 when clamping the workpiece.

At this time, rotating the control member 19 again can reset the rotating disk 11 and the extrusion cam 10.
[0020] When clamping the workpiece, place the workpiece between the first fixed block 4 and the second fixed block 18, rotate the double-headed threaded column 3, and the double-headed threaded column 3 can drive the first fixed block 4 and the second fixed block 18 to move toward the middle to perform preliminary clamping on the workpiece. At this time, the buffer spring 8 can buffer the clamping force to avoid damage to the workpiece. Plug the control part 19 and the rotating disk 11 together, and drive the rotating disk 11 to rotate. The extrusion cam 10 squeezes the connecting wheel, thereby pushing the mobile clamping block 6 to move. The moving distance of the mobile clamping block 6 can be finely controlled to avoid damage to the workpiece.
