In the construction field, distance meters are widely used to measure the height of a house, the length of a wall, angles, and other complex dimensions. Architects can use this data to design building plans and ensure that the house meets specifications and safety standards.

[0003] In the prior art, such as announcement number CN219432910U, a rangefinder for construction exploration is disclosed, including a base, a telescopic rod is fixedly connected to the top of the base, a limiting block is slidably connected to the outer side of the telescopic rod, a first limiting hole is opened on the side of the limiting block, a U-shaped limiting rod is inserted into the inner wall of the first limiting hole, an electric slide is slidably connected to the side of the U-shaped limiting rod, and a rangefinder is fixedly connected to the top of the electric slide.
