The rangefinder can be supported on the ground by the tripod bracket, and the horizontality of the rangefinder placement state can be observed through the level bubble on the outer surface of the fixed platform. If the ground is tilted, the angle of the rangefinder can be adjusted by rotating the rolling ball on the lower surface of the fixed platform. The rolling ball can increase the angle adjustment range of the rangefinder and improve the adjustment efficiency.

[0004] During the use of the above-mentioned rangefinder, we found that the adjustment angle of the rangefinder is limited and it is impossible to achieve measurement at any angle.
