Lightning triggering protection device of OPGW distribution line and use method

The invention discloses a lightning guiding protection device of an OPGW distribution line and a use method. The device comprises a composite insulator umbrella skirt, a lightning guiding rod fixed on the composite insulator umbrella skirt, a lightning guiding rod matched with the lightning guiding rod, and a connecting mechanism. The connecting mechanism comprises an adjusting assembly. The adjusting assembly comprises an insulating porcelain seat fixedly connected to the bottom end of the umbrella skirt of the composite insulator; the side surface of the insulating porcelain seat is fixedly connected with a U-shaped guide rail; the inner side of the U-shaped guide rail is movably connected with an end base, and clamping grooves are formed in the two sides of the inner wall of the U-shaped guide rail. Clamping edges are arranged on two sides of the surface of the end seat; the two clamping edges are connected into the clamping grooves in the same side in a sliding mode respectively, the clamping edges and th
