The cooperation between the ball bearing and the shaft is in the form of interference fit or clearance fit, which is more convenient for installation and the force direction is relatively stable, so the installation error has less impact on it. The lead screw 22 movably penetrates through the lower frame 1 and extends upward. A threaded connection is provided between the outer wall of the lead screw 22 and an upper frame 23. The top of the lead screw 22 is fixedly connected to a knob 24. By turning the knob 24, the lead screw 22 is rotated, thereby driving the upper frame 23 to move downward. A first conical block 26 is fixedly connected to the top of the lower frame 1, and a second conical block 27 is fixedly connected to the top of the lower frame 1. An installation groove 25 is formed at the top of the upper frame 23.
