The impact of drilling by the handle body, push lever, cylinder, head, putting other components. Pressure gas pipe connecting pipe from entering the gas pressure regulator handle carried into the cylinder, and then by the fader or simply turning the line into shock impact, so as to achieve the role of shock or rotation.
