[0002] A laser rangefinder is a high-precision instrument (also called laser rangefinder) that uses laser technology to accurately measure the distance to a target. During operation, the instrument emits a fine laser beam pointing to the target, and the laser beam reflected by the target is captured by a photodetector. By measuring the time difference from the laser emission to the reception, the exact distance from the observation point to the target can be calculated. This technology is extremely excellent in accuracy and reliability and is widely used in many fields, including construction measurement, topographic mapping, and long-distance precise positioning.

[0003] When operating a laser rangefinder, it is mostly hand-held, because the hand-held method cannot keep the laser rangefinder in a horizontal state. Therefore, in the prior art, a bracket is used to support the laser rangefinder to ensure its horizontal placement and stability.
