A coaxial limiting sleeve is arranged at the center of the polishing wheel 7, and a plurality of waist-shaped holes are evenly arranged axially on the limiting sleeve. A threaded groove corresponding to the waist-shaped hole is arranged on the screw 6, and the locking rod passes through the waist-shaped hole and is screwed in the threaded groove. The return spring and the screw cooperate with each other to ensure that the polishing wheel is always subjected to a force in a direction away from the screw. Such an arrangement can give the polishing wheel a certain amount of reserve before the polishing operation, so that there is no need to manually adjust the position of the polishing wheel during the polishing operation.
