Laser range finder for supervision

The utility model discloses a laser range finder for supervision, relates to the technical field of engineering supervision, solves the problem that a lens of a laser probe is exposed in an external environment for a long time and is easy to damage, and comprises a range finder body, the laser probe, a protection shell and a baffle plate, and a driving assembly is connected to the middle of the two-way screw rod, threaded sleeves are fixedly connected to the lower surfaces of the two baffles, and the two threaded sleeves are connected to the two sides of the two-way screw rod in a threaded and sleeving mode correspondingly. The laser probe can be protected through the protective shell, the situation that a lens of the laser probe is prone to being scratched or broken is reduced, in the using process, the driving assembly can be used for driving the two-way screw to rotate, the two threaded sleeves move oppositely or oppositely in the length direction of the two-way screw, and therefore the two baffles are dri
