The worm gear 45 drives the threaded rod 43 under the restriction of the worm 48 to move, and the threaded rod 43 drives the fixing plate 4 to move, and the fixing plate 4 drives the detection lens 2 on the shock absorbing assembly 3 to move in the vertical direction, so that the photoelectric detector body 1 can be conveniently moved to any different height for use, thereby increasing the convenience of using the photoelectric detector body 1. At the same time, the reverse self-locking characteristics of the worm 48 and the worm gear 45 can be used to lift the photoelectric detector body 1 to any height for automatic locking. It is not only simple in structure, but also convenient to use.

[0023] Embodiment 2: On the basis of Embodiment 1, in order to facilitate the protection of the surface of the detection lens 2, a protection mechanism is arranged, which specifically includes two positioning blocks 5, both of which are mounted on the photodetector body 1, and protective cover plates 51 are rotatably mounted on the two positioning blocks 5, and the protective cover plates 51 are in contact with the detection lens 2.
