Then, the user can drive the first rotating shaft 8 and the mounting plate 2 to rotate by the first motor 7, so that the workpiece swings. At the same time, the user can drive the gear 18 to rotate by the second motor 17, and then the workpiece rotates with the cooperation of the annular tooth groove 19. This allows the user to easily grind the workpiece from multiple angles.
