Description

Technical Field

[0001] The utility model relates to the technical field of engineering cost, in particular to a laser rangefinder positioning device for engineering cost. Background Art

[0002] A laser rangefinder is an instrument that uses a certain parameter of modulated laser to measure the distance to a target. When working, the laser rangefinder emits a very thin beam of laser to the object to be measured. The photoelectric element receives the light beam reflected by the object to be measured. The timer measures the time from the emission to the reception of the laser beam, thereby calculating the distance from the observer to the object to be measured. It can be often seen in engineering cost.

[0003] In the prior art, when a laser rangefinder is used, the rangefinder is usually fixed on a supporting tripod. However, if the ground is uneven, the tripod may be skewed or even fall over, affecting the normal use of the laser rangefinder. In addition, in order to ensure the accuracy of the measurement, it is necessary to move the position for multiple measurements, and the movement of the tripod is relatively troublesome.
