[0032] The driving motor 310 drives the threaded screw 311 to rotate. Since the support seat 320 is threadedly engaged with the threaded screw 311 and the rotation direction of the support seat 320 is restricted, when the threaded screw 311 rotates, the support seat 320 is translated along the direction of the slide slot 220, thereby realizing automatic feeding of the cam component 100.
