Fire gun buckle

The utility model discloses a fire-fighting lance buckle which comprises a fire-fighting lance buckle body and further comprises a buffering mechanism which is arranged in a connecting pipe and used for buffering instant impact force generated when high-pressure water flow just enters a fire-fighting lance, and the buffering mechanism comprises a first circular plate connected in the connecting pipe in a sliding mode. A second circular plate is slidably connected to the side, away from the buckling pipe, of the first circular plate, a circular ring is slidably connected to the inner wall, close to the threaded pipe, of the connecting pipe, a spring is fixedly connected to one side of the circular ring, and the other end of the spring is connected with the second circular plate. According to the utility model, through the arrangement of the buffer mechanism, high-pressure fire-fighting water is buffered by utilizing the elastic force of the spring, so that the instant impact force generated when high-pressure
