In the invention, when the step (II) is implemented, the deviated outgoing line needs to be corrected to a proper position and the reserved length needs to be measured manually, and the redundant tapping lead needs to be cut off manually by using a tool clamp, so that the problems of high labor intensity and low efficiency exist.
