The movement of the second threaded rod 11 drives the second sleeve 8 installed on its lower end surface to move, thereby driving the connecting block 7 and the first sleeve 6 to follow the movement, and the movement of the first sleeve 6 drives the column 4 set inside it to move. The movement of the column 4 drives the splint 3 and the slide rod 5 to move, and the slide rod 5 slides inside the lower end of the support frame 2. The movement of the splint 3 can clamp the two sides of the workpiece, and then the rotating block 12 is rotated to drive the second threaded rod 11 to rotate in the internally threaded slider 16, and at the same time rotate inside the second sleeve 8, so that the internally threaded slider 16 moves downward, and at the same time drives the second sleeve 8 installed on its lower end surface to move downward, and drives the connecting block 7 and the first sleeve 6 to follow the movement. At this time, the first sleeve 6 will slide on the outside of the column 4, so that the bottom of the second threaded rod 11 can be pressed against the upper surface of the workpiece, greatly improving stability.
