I assume it should be something like "insert the wire and the guiding steel wire, and pull the steel wire to lay the wire in the wire pipe. During the pulling process, at the switches and sockets at the entrance part, due to the lack of auxiliary tools, the angle between the wire and the inner socket box is very small, and the wire directly rubs against the inner socket box when being pulled, which will cause wire damage and reduce the operation efficiency.
