  • Publication number: 20050017047
    Abstract: The nail-guiding grooves of the nail cartridge of a nailing gun are respectively formed integral with a combining groove at a preset portion of one side on which the nail heads of a nail row rest. An abrasion-resisting plate of high strength and high wear-resistance is fixedly received in the combining groove. The nail heads of the nail row rest against the abrasion-resisting plate and shift thereon in the process of nail striking so as to avoid being worn out of the wall corners of the nail-guiding groove being worn out by the nail heads of the nail row, enabling the nail row shift and supply nails smoothly, preventing nails from being deadlocked and prolonging service life of the nail cartridge.
