The line pendant is also called a plumb weight, which refers to a metal (iron, steel, copper, etc.) For the conical object, connect the pendant with the pay-off line and roll it to the bottom of the brick wall, and check whether the wall is vertical by the degree of fit between the set-out line and the brick wall;

The connecting thread used in the existing thread pendant is cotton thread, and the cotton thread will generate static electricity on the surface after repeated unwinding and rewinding, which is prone to entanglement and knotting. Unwinder, used in conjunction with the wire pendant, detects the length of the wall for unwinding according to needs, and rewinds the wire rope after use, which is easy to use;

However, the existing winding method uses a winding shaft to rewind the cord in a winding manner, which may easily cause the cord to become entangled and knotted due to the overlapping and covering of each other during the winding process, causing the thread to be twisted when it is used next time. The problem that the rope is stuck and cannot be released.
