The clamping seat, the movable part and the cam are combined, thereby enabling the cam to drive the movable part to slide up and down in a clamping groove of the clamping seat during rotation. When the movable part moves to an upper end, an LC light port of a plastic lens can be inserted into the clamping seat without obstruction. When the movable part moves to a lower end, the LC light port of the plastic lens is limited by a limiting gap of the movable part. When the cam rotates, the cam drives the movable part to slide to the upper end to replace the plastic lens with a new plastic lens. Accordingly, the present invention solves the technical problems of enabling the plastic lens to be easily positioned and bind a PCB, thereby achieving the beneficial effects of improving the quality and the efficiency and reducing the manufacture cost.
