[0001] The utility model relates to the technical field of total station accessories, in particular to a leveling device for a total station. Background Art

[0002] A total station, also known as a total station electronic tachometer, is a device that can conduct observations at a side station and automatically display necessary observation data. It is widely used in precision engineering measurements or deformation monitoring fields such as large-scale above-ground buildings and underground tunnel construction. During the use of the total station, a total station leveling device is required to support and level the total station, which simplifies the leveling work, reduces the workload, shortens the leveling time, and thus improves work efficiency.
