[0002] Building quality inspection rulers are mainly used for construction and completion quality inspection of engineering construction, decoration and renovation, bridge construction, equipment installation and other projects. They mainly include vertical inspection rulers, diagonal inspection rulers, internal and external right-angle inspection rulers and vernier feeler gauges.
[0003] When using traditional measuring equipment, scales are often directly carved on the outer wall of the ruler to measure the outer wall of the building wall. However, when not in use, the traditional measuring ruler is often placed directly on the ground or stored in a tool box. The scale on the outer wall of the measuring ruler will be worn during transportation, resulting in unclear scales, thereby affecting the measurement accuracy of the measuring ruler. In addition, the function of the traditional measuring ruler is relatively single, and it can only measure length. Utility Model Content
