[0002] Land surveying and mapping devices are professional equipment used to measure and map land topography, location, area and other information. These devices combine modern technology with traditional surveying technology, greatly improving the accuracy and efficiency of measurement. Among them, the acre meter is one of the commonly used devices in land surveying and mapping. It uses an intelligent positioning system with wide signal coverage and a positioning accuracy of up to 0.002 kilometers. It can provide longitude and latitude positioning information in real time. The acre meter supports multiple measurement modes to meet the area and distance measurement needs in different scenarios. In addition, it also has data recording and export functions, which is convenient for users to check and analyze data at any time. In addition to the acre meter, total stations, GPS receivers, levels, etc. are also commonly used devices in land surveying and mapping. These devices play an important role in land surveying, road construction, construction engineering and other fields, and provide important support for the country's infrastructure construction and economic and social development.

[0003] Land surveying requires the use of a surveying instrument. Existing surveying instruments can usually only be adjusted through support feet during use. When encountering rugged terrain, the angle cannot be adjusted efficiently, which reduces the efficiency of the surveying instrument and is not conducive to user use.
