Description

Technical Field

[0001] The utility model relates to the field of building electromechanical equipment installation, in particular to a building electrical wire threader. Background Art

[0002] A wire threader is a commonly used tool in the installation of mechanical and electrical equipment in buildings. It is mainly used to help pass wires or cables through pipes, ducts, cable ducts or other similar spaces. It usually consists of a long, flexible rod or wire with a device at one end that can grab the wire or cable. Existing building electrical wire threaders still have many shortcomings. First, some building electrical wire threaders cannot clamp the spool after retracting and releasing the wire. The cable may slide or move during the threading process, which may cause the cable to be inaccurately positioned. Secondly, the cable may carry dust and other impurities in the pipe during the threading process, which may affect the performance and life of the cable. Finally, some building electrical wire threaders cannot adjust the tightness of the wire threader according to the size of the cable and the length of the pipe, which may cause the cable to be too loose or too tight during the threading process, thereby affecting the performance of the cable.
