[0002] Steel grid structure is a spatial structure made of steel, usually used in large-span buildings and facilities such as stadiums, exhibition centers, airport terminals, etc. Compared with traditional concrete structures, steel grid structure can provide stronger load-bearing capacity at a lighter weight due to the use of steel.

[0003] The steel grid structure needs to be inspected using a detection device during installation. During use, the existing detection device usually monitors the steel grid through a total station. However, the total station is susceptible to external force collision during transportation, which can cause damage to the internal parts of the total station. At the same time, the monitoring lens of the total station is susceptible to scratches and wear during transportation, affecting the monitoring accuracy. In addition, the bracket of the total station is inconvenient to fold and store, and occupies a large area, which affects the subsequent storage and transportation of the total station.
