Problems solved by technology
[0002] During the installation and construction of fire protection engineering facilities, it is usually necessary to reserve holes in the indoor and outdoor partition walls for the installation of fire protection facilities. Therefore, it is necessary to use a positioning device to locate the holes. The current positioning device is suitable for use in a flat ground environment. Often the construction ground is uneven or inclined, causing the reserved holes to tilt, resulting in unsightly installation of fire-fighting facilities. At the same time, the current positioning device is not suitable for the positioning of reserved holes with a fixed inclination angle, which limits the scope of use.
