Horizontal calibration mechanism based on optical lens

The invention relates to the technical field of laser measurement, in particular to a horizontal calibration mechanism based on an optical lens, which comprises a sliding plate, the two side edges of the sliding plate are fixedly connected with side folding plates respectively, the upper surfaces of the two side folding plates are fixedly connected with concave frames respectively, and the inner sides of the concave frames are elastically connected with movable plates along the vertical direction. Connecting rods extend out of the sides, close to each other, of the two movable plates respectively, a contact ball is rotationally connected between the two connecting rods jointly, synchronous rods are fixedly connected to the sides, close to the front ends, of the two movable plates respectively, and limiting columns extending downwards are fixedly connected to the ends of the synchronous rods. According to the scheme, the device can be arranged on a lens conveying line, the continuity of the whole conveying lin
