[0002] The welding ground wire expansion device is used in power construction, especially in the construction of high-voltage power transmission lines. It is a device that must be used to ensure construction safety. Traditional grounding devices usually include an insulating rod, a metal hook, a grounding wire and a grounding electrode, wherein the insulating rod and the metal hook are fixedly connected as one body, and a spring clip for clamping the substation line is provided in the metal hook. One end of the grounding wire is connected to the metal hook and the other end is connected to the grounding electrode. The grounding device of this structure is inconvenient to use. For example, the insulating rod has different lengths according to different voltage levels, and one rod cannot be used for multiple purposes, resulting in the construction department needing to be equipped with grounding devices of multiple specifications at the same time, which is not conducive to cost saving. In addition, insulating rods with high voltage levels and long lengths are not easy to store and transport, causing inconvenience in transportation.

At the same time, the utility model can prevent the problem of grounding wire entanglement in the traditional grounding wire during the rotation of the pipe.
