Portable short-circuit grounding wire

The invention discloses a portable short-circuit grounding wire which comprises an operating rod, a first clamp, a wire and a second clamp, two clamping pins are fixed to the operating rod, the first clamp comprises a connector, a V-shaped plate and two vertical rods, the vertical rods and the connector are fixed to the two sides of the V-shaped plate respectively, the connector is provided with a sliding groove and a clamping groove communicated with the sliding groove, and the clamping groove is communicated with the V-shaped plate. An elastic assembly is arranged in the first clamp, the clamping pin slides into a notch of the clamping groove along the sliding groove, the elastic assembly is used for limiting the clamping pin in the clamping groove, the two vertical rods and the V-shaped plate form a U-shaped groove, elastic pieces are arranged at the ends, away from the V-shaped plate, of the vertical rods, and the distance between the two elastic pieces is smaller than that between the two vertical rods.
