[0002] A photoelectric measuring instrument is an instrument that uses the principle of the photoelectric effect to measure various physical quantities of an object. It mainly involves photoelectric components such as photoelectric sensors, photoelectric switches, and photoelectric encoders.

The inner walls of the two slide grooves are slidably connected to the same lifting mechanism, the inner wall of the groove is rotatably connected to a screw, and the outer wall of the screw is screwed with a threaded block, and the threaded block is fixedly connected to the lifting mechanism, the top outer wall of the support base is fixedly connected to a reduction motor, and the output shaft of the reduction motor is connected to the screw. By arranging the screw on the support base, the cooperation between the screw and the reduction motor facilitates the direct drive of the lifting mechanism to move, and when the lifting mechanism moves, the lens group is directly driven to rise and fall.
