[0002] There are many types of construction engineering surveying equipment, each of which has its specific purpose and function. Some common construction engineering surveying equipment include: level, theodolite, total station and global positioning system.

[0003] The optical level is a measuring tool widely used in the fields of construction engineering, civil engineering, etc. It mainly uses the principle of light reflection and refraction to accurately measure the horizontal plane. The optical level has a built-in convex lens, which allows the light to converge naturally and produce parallel light. When these parallel light rays touch the horizontal plane, reflection occurs. Through the reflector in the optical level, the horizontal light is reflected to the observer's eyes, forming a horizontal line, indicating the position of the horizontal plane. The observer can fine-tune the reflector position to accurately align the horizontal line with the reflector, thereby determining the exact position of the horizontal plane.

[0004] The existing technology has the following problems: in the adjustment of the optical level, the opening angle between the support rods and the height of the push rod are adjusted to make the optical level reach different heights. In some occasions, the height adjustment of the level is repeatedly adjusted by relying on the opening angle between the support rods and the push rod, which leads to cumbersome steps and low work efficiency.
