Preferably, the end face of described U-shaped left side brace and the end face of U-shaped right side brace are riveted by bolt.
Preferably, the end face of described U-shaped left side brace and the end face of U-shaped right side brace pass through rivet.
The utility model is further improved and is: described telescopic insulation rod is provided with reflective vitta and spaced apart.
The beneficial effect that technique scheme produces is:
One, the utility model is by the angle between adjustment U-shaped right side brace and telescopic insulation rod, the hanging ground-wire tie point of different angles can be adapted to, especially handled easily person stands on tower bar and carries out hanging ground-wire operation to the vertical lead wire of overhead, eliminate the risk that when operating personnel hangs earth connection, health significantly tilts, can safety be ensured, avoid personal injury, raise labour efficiency.
Two, this earth connection, by the length of adjustment insulating telescopic bar, can meet the requirement of different distance when hanging earth connection, make easy and simple to handle.
Three, telescopic insulation rod is provided with reflecting at night vitta, facilitates when insufficient light or night-time observation ground wire installment state.
