摘要

Pliers for devices to operate from the soil the short-circuiting and grounding of conductors of mean-voltage overhead electric lines. Said pliers are of the type with movable jaw (3), which closes automatically when contacting the conductor (C), and they are mounted at one end of a telescopic metal support rod (8). The end portion of said support rod (8) is connected to the pliers body (1) in at least two points, of which a first point of permanent anchorage consists of a hinge (9-10), and at least a second point consists of a coupling (8i-11) disengageable at will by imparting some movements to the rod (8) supporting the pliers.
