In the current construction field, most of the distance measuring devices are phase type laser distance measuring devices, and according to the actual use scene, the distance measurement can be carried out indoors with the assistance of a handheld or tripod, and the principle is that the distance between the distance measuring device and an object is calculated through time intervals by emitting a particularly short light pulse and measuring the time from the emission of the light pulse to the reflection of the light pulse by the object.

In the actual use process, as the distances between different wall surfaces and different rooms are required to be measured, the angle between the range finder (the surface emitting light pulses) and the measured object is continuously adjusted, in the prior art, a worker either holds the range finder to measure, mostly judges whether the range finder and the measured object are kept in a vertical state or not through visual inspection, but the small angle can cause deviation of the measurement result, and the risk that the calibration accuracy is hindered by the barrier (for example, the barrier exists at the measured point) is also caused by the fact that the measuring tape is directly placed on the ground to calibrate.

However, some distance measuring devices capable of electrically adjusting the angle are expensive, increase the cost and carrying load of workers, and are not suitable for all construction scenes.

The utility model aims to construct a building ranging device, which can quickly and conveniently adjust the angle and simultaneously lead the angle adjustment to be more accurate.
