[0002] In physics, we often need to measure and judge the horizontal state of an object. This is where a spirit level comes in handy. A spirit level is a measuring tool whose working principle is based on the direction of gravity. By sensing the interaction between gravity and the spirit level, it indicates the horizontal state of an object. The level tube, as the core component of the spirit level, is a sealed glass tube filled with a liquid that has excellent fluidity and does not freeze easily. It is equipped with an air bubble. When the spirit level is in a horizontal or vertical state, this air bubble will remain stationary at a specific position in the level tube, usually at the central scale. Construction workers on construction sites can use spirit levels to ensure the accuracy and efficiency of their work. This device is a flatness detection device for the quality of civil engineering projects.

[0003] Some flatness testing devices can be used with lasers for large-space measurements. They are usually used with a support bracket, which is inconvenient.

[0004] Therefore, a flatness testing device for civil engineering projects is needed to solve the above problems. Utility Model Content
