Description

Technical Field

[0001] The utility model relates to the technical field of laser rangefinders, in particular to a laser rangefinder which is easy to fix. Background Art

[0002] A laser rangefinder is an instrument that uses a certain parameter of a modulated laser to measure the distance to a target. The measurement range of a laser rangefinder is 3.5 to 5000 meters. According to the distance measurement method, it is divided into a phase rangefinder and a pulse rangefinder. A pulse laser rangefinder emits a beam or a series of short pulsed laser beams to the target when working. The photoelectric element receives the laser beam reflected by the target, and the timer measures the time from the emission to the reception of the laser beam, and calculates the distance from the observer to the target.

[0003] The laser rangefinder needs to be fixed when in use to avoid tilting during distance measurement, which would cause errors in the detection results and affect people's engineering construction. However, most of the existing laser rangefinders are not easy to fix. The laser rangefinder is not fixed firmly enough and is prone to deviation and shaking, which leads to errors in the measurement results and is not conducive to practical use. Utility Model Content
