Extensible connecting rod externally connected with electric leakage detector

The invention relates to the technical field of cable leakage detection, in particular to a telescopic connecting rod externally connected with a leakage detector, which comprises a leakage detection assembly, a wire detachably arranged on the outer wall of the leakage detector, a rotating rod arranged at the other end of the wire, a threaded groove formed in the outer wall of the rotating rod, and a hook arranged at the other end of the rotating rod, the mounting frame is arranged outside the rotating rod, the rotating cylinder is arranged at one end of the mounting frame, and the first limiting block is arranged on the inner wall of the rotating cylinder and can slide along the interior of the threaded groove. According to the method, cable data is detected in two steps, a clamp is operated to ground a cable, and after clamping is determined, an electric leakage detector is switched on to read current data; and meanwhile, manual climbing on a cable is not needed, operation can be conducted on the ground, th
