High-precision positioning device adopting magnetoelectric scanning encoder

The utility model relates to the technical field of high-precision positioning, in particular to a high-precision positioning device adopting a magnetoelectric scanning encoder, which comprises a machine body and a base, a supporting seat is fixedly mounted on the surface of the base, and a connecting block is arranged on the surface of the supporting seat. Through cooperation of the fixed block, the movable column, the rotating shaft, the movable shaft, the movable rope, the pull rod, the limiting plate and the reset spring and connection of the fixed block and the movable column, after the pull rod is pulled to drive the movable rope, under the limiting effect of the pull rod, the movable shaft connected with the movable rope drives the movable column to rotate, and under the effect of the rotating shaft, the movable rope is driven to rotate. And after the movable shaft rotates, the front end of the movable column rotates in the opposite direction, then limiting on the detector is relieved, under the action
