The invention discloses a telescopic insulation rod device. The telescopic insulation rod device is used for ground electricity testing and ground picking and hanging grounding wires of sets of grounding wire used for overhead lines. The telescopic insulation rod device comprises a telescopic insulation rod and an insulation clamping pipe, wherein the telescopic insulation rod comprises at least two sections of insulation rods which are sequentially sleeved in an embedded mode. A lock catch device is arranged at the joint of each two adjacent sections of insulation rod. One end of the telescopic insulation rod is connected with the insulation clamping pipe, and the other end of the telescopic insulation rod is a holding end. A first hole cavity and a second hole cavity which are communicated in a stair-shaped mode are formed from one end of the insulation clamping pipe to the interior of the insulation clamping pipe, wherein the first hole cavity is used for accommodating an electroscope handle and the second hole cavity is used for accommodating a grounding rod handle. An L-shaped opening is formed in the insulation clamping pipe, and the telescopic insulation rod is fixedly connected to one end, the first hole cavity is not formed, of the insulation clamping pipe. The telescopic insulation rod device is simple in operation, saves labor and time, and can ensure personal security and greatly shorten time for testing electricity and picking and hanging the grounding wires.
