Efficient eccentric surface treatment polishing machine

The efficient eccentric surface treatment polishing machine comprises a machine base, a protruding block is fixedly connected to the machine base, a transverse groove is formed in the protruding block, and a movable block in sliding connection is arranged on the protruding block. According to the polishing device, the distance between moving blocks is adjusted according to the size of a to-be-polished piece, a bent block is pulled upwards, a first spring is stretched till the bent end of the bent block is separated from a clamping groove, at the moment, the moving blocks can be pushed to move in the horizontal direction, and bottom blocks fixedly connected to the bottoms of the moving blocks slide in transverse grooves; a side block fixedly connected with the side wall of a bottom block slides in a side groove formed in a protruding block, when a movable block moves to a proper position, force on a bent block is released, the bent block can automatically move in the vertical direction under the action of a fi
