technical field

The utility model relates to the technical field of leveling instruments, in particular to a land surveying leveling instrument.

Background technique

At present, the leveling instrument is an instrument that establishes a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between ground points according to the principle of leveling. The main components are telescope, tube level (or compensator), vertical shaft, base, foot screw. According to the structure, it is divided into micro-tilt level, automatic level, laser level and digital level (also known as electronic level). According to the accuracy, it is divided into precision level and ordinary level. In land surveying engineering, a land surveying level is usually used to measure the land to be measured.
