The root of the shifting rod 311 is fixedly installed at an eccentric position (a position away from the center of the circle) of the circular turntable 310. The power mechanism includes a clamping motor 303 fixedly installed on a bracket 302, and the root of the bracket 302 is fixed on the outer wall of the translation box 301. The output end of the clamping motor 303 is connected to a driving shaft 304, and the driving shaft 304 is connected to the gear shaft of the first gear 305.
