[0021] The section of the carrying plate 6 is L-shaped, two pneumatic polishers 7 are fixed on the longitudinal plate of the carrying plate 6, each of the pneumatic polishers 7 corresponds to a welding position on the side edge of the clutch booster support, that is, the position where the two ends of the rib plate of the clutch booster support are welded to the two base plates, the output end of the pneumatic polisher 7 is fixed with a grinding disc 8, the grinding disc 8 is a flexible grinding disc 8, which can be a louvered disc, a fiber elastic grinding disc or a nylon abrasive sheet, so that in the polishing process, the two carrying plates 6 on the two sides are controlled to move close to each other, and after moving the same distance, the four grinding discs 8 can abut against the four polishing positions of the clutch booster.
