At present, the light source in the laboratory environment is generally fixedly installed. Considering the accumulation of tolerances when assembling accessories, the installation position of the light source may not be accurate, but it cannot be adjusted because of the fixed installation, or some experimental scenarios also need to fix the light source in different positions. The existing technology structure cannot meet the situation in these scenarios. Utility Model Content
