Each abrasive assembly is mounted in the base above the belt and has a rotating axle and an abrasive brush mounted around the rotating axle. The reciprocating device is connected respectively to the abrasive assembly and has a driven axle coaxially connected to the rotating axle of the abrasive assembly to allow the rotating axle to move reciprocatorily and linearly. The driving device is connected to the reciprocating device, drives the rotating axle of the abrasive assembly and has a couple to rotate the driven axle of the reciprocating device.
