[0047] The driving member 221 drives the cam block 223 to move along the second direction Y, and the sliding member 224 slides in the slideway 2231. Since the slideway 2231 is inclined to the first direction X, the sliding member 224 moves in the first direction X, driving the grinding assembly 210 to move along the first direction X.
