When in use, the second lifting sleeve 2 is first driven by the screw lifting assembly to slide and lift in the first lifting sleeve 1, so as to adjust the height of the rotating rod 3, and stop after the adjustment is completed. When grinding, the rotating rod 3 is driven by the cylinder lifting assembly to be slightly lifted and lowered, so as to adapt to the need to adjust at will according to the different heights of special-shaped stones during grinding, so as to achieve separate adjustment and increase grinding accuracy.
