Finally, the diamond composite sheet will be subjected to impact force during the grinding process, and the movement of the connecting block 10 drives the rotating rod 12 to rotate. When the connecting block 13 moves downward, the rotating rod 12 rotates clockwise to generate thrust to push the slider 10 to move.
