[0002] Geographic information surveying instruments are instruments used for orientation, distance, angle, height, mapping and photogrammetry according to the needs of the work. They are often used in the field of geological exploration. In the process of geographical environment research, the accuracy of geological exploration plays a vital role in helping the study of geographical environment. In actual use, surveying instruments are often used in the field to carry out related surveying and mapping tasks.

[0003] When a surveying instrument is in use, a tripod is usually required to support the surveying instrument. However, when conducting surveying work in the field, the instrument supported by the tripod is usually not stable enough. Since the terrain in the field is inconsistent, the level of the tripod cannot be guaranteed, and thus the horizontal measurement of the surveying instrument cannot be guaranteed. At the same time, the surveying instrument supported by the tripod cannot be raised or lowered, and cannot be guaranteed to be suitable for surveying personnel at different heights. The tripod has great limitations and cannot meet the needs of actual use. Therefore, the market is in urgent need of improved technologies to solve the above problems. Utility Model Content
