At the same time, the electric push rod extension state is adjusted to a state that does not affect the installation of the wire clamp 1 (the electric push rod 1 14, the electric push rod 2 11 are extended, and the electric push rod 3 9 is retracted).

[0041] Manually make the wire clamp 1 in the fully open state, install the wire clamp 1, adjust the telescopic state of the electric push rod to clamp the wire clamp 1 (electric push rod 1 14, electric push rod 2 11 retract, electric push rod 3 9 extend), so that the wire clamp 1 remains in the fully open state.
