Description

Technical Field

[0002] As we all know, laying wires and cables is a common task in electrical engineering, especially in the fields of construction, communications and industry. In order to protect the cables, they need to be threaded into conduits. Currently, one end of the cable is usually fixed to a threading rod manually, and the threading rod is manually operated to pass through the conduit to thread the wires. However, the disadvantage of manual operation is that workers often need to bend over, which increases their fatigue. In order to solve the above problems, automatic threaders came into being. Automatic threaders can automatically complete the laying of wires and cables, improve laying efficiency, reduce labor costs, and ensure laying quality.

[0003] When an existing automatic wire threader is in use, a worker fixes the cable to be threaded through a fixing mechanism, then slides the fixing component into the sleeve, starts the power mechanism, and moves through the traction component until the threading is completed. However, when the existing automatic wire threader is in use, it is found that it is impossible to quickly clamp and fix wires and cables of different specifications and sizes, and its fixing mechanism needs to be replaced, thereby reducing the work efficiency and effect of the worker in threading the cable, resulting in poor practicality.
