[0002] In recent years, with the increase in the scale of power grid development and the service life of equipment, the pressure on the operation and maintenance of power grid equipment has increased significantly. For most maintenance and operation work, in order to effectively ensure the safety of personnel operations, it is necessary to isolate the equipment in the operation area from the operating equipment and provide grounding protection. Currently, the conventional grounding method is to connect the grounding clip of the grounding wire to the grounding point, and the other end contact clip is clamped to the wire or other metal parts through a single or spliced insulating operating rod.

[0003] However, due to different voltage levels and different spatial volumes of power grid equipment, especially the higher the voltage level, the higher the spatial height of electrical equipment; at the same time, the wires that need to be grounded and isolated are not horizontally arranged, and there are vertical or inclined angles in reality. Therefore, using the conventional grounding method not only takes time and effort, but also the reliability of grounding wire installation cannot be fully guaranteed. Therefore, how to develop a telescopic multi-angle grounding wire operating rod has become an urgent problem for technicians in this field. Summary of the Utility Model

The top end of the first insulating tube is inserted into the bottom end of the second insulating tube, and a telescopic joint is provided at the overlapping part of the first insulating tube and the second insulating tube.

[0011] Further, the telescopic joint includes a special-shaped sleeve and a special-shaped threaded tube. The special-shaped threaded tube includes an upper tube with threads on the outer surface and a lower tube with a smooth outer surface that is equally divided and tapered inwards.
