  • Patent number: 7637406
    Abstract: The present invention relates to a nail shooter. The present invention provides the nail shooter driven by a high-pressurized gas in liquid state, in order to resolve technical problems with the prior nail shooters, such as difficulty in application, a loud noise, a safety hazard. The shooter body is provided with a trigger mechanism, a firing pin used for striking a nail to get it shot, a piston mechanism for pushing the firing pin, and a switch mechanism for releasing the driving gas toward the piston mechanism. The handle of the nail shooter is provided with a coupling tube, which is provided with an intake joint used for introducing the gas from a cylinder containing high-pressurized gas in liquid state and further with a decompressor that decompresses the introduced gas. Under control of the trigger mechanism, the decompressed gas can drive the piston mechanism to act via the switch mechanism, and further push the firing pin to strike a nail at a high speed to get it shot.
