The invention discloses a ground wire anti-fall protection device which solves the technical problem that a conventional portable short-circuit ground wire is inconvenient to hang and unlock. The ground wire anti-fall protection device includes a wire clip connected to a ground wire. The wire clip includes a left wire clip and a right wire clip that are hinged to each other. A torsion spring is disposed at the hinge of the left wire clip and the right wire clip. The two tail ends of the torsion spring are abutted against the inner side of the left wire clip and the inner side of the right wireclip. The right wire clip is hinged to a locking lever at the outer end surface of the lower side of the torsion spring. The locking lever is connected with a traction rope. The end portion of the locking lever away from the hinged end is connected with a right wire clip stopper. A passage groove is disposed on the locking lever. A stop surface is disposed in the passage groove. The left wire clip is hinged to a support rod in clearance fit with the stop surface. The ground wire anti-fall protection device can remotely control the opening and closing of the wire clip through the traction rope, thereby conveniently connecting or disconnecting a portable ground wire to or from a high-voltage wire.
