    • A hammer-drive powder-actuated tool includes a hollow tool body extending along a front-to-rear direction, and a firing device disposed within a rear end portion of the tool body. The firing device includes a pin holder having a through hole extending along the front-to-rear direction, and a firing pin movable forwardly and rearwardly relative to the pin holder. The pin has a firing end portion that is disposed at a front end thereof and that extends into the through hole in the pin holder, and a central axis aligned with that of a rimfire cartridge along the front-to-rear direction. A front end of the firing end portion of the firing pin has a diameter larger than the inner diameter of the annular primer and smaller than the outer diameter of the annular primer.
    • 锤式驱动粉末致动工具包括沿着前后方向延伸的中空工具主体,以及设置在工具主体的后端部内的点火装置。 点火装置包括具有沿着前后方向延伸的通孔的销保持器和能够相对于销保持器向前和向后移动的撞针。 销具有设置在其前端并且延伸到销保持器中的通孔中的击发端部分,以及沿着前后方向与中心轴线对准的中心轴线。 撞击销的击发端部的前端的直径大于环形底漆的内径,并且小于环形底漆的外径。

    • Explosive actuated tool for driving element by explosive charge comprises barrel having bore therein for positioning element to be driven by tool. Muzzle is provided at one end of barrel, and explosion chamber communicates with bore for receiving percussion ignitable explosive charge whereby when explosive charge is ignited element positioned within bore is driven from muzzle of tool. Closed gas expansion chamber surrounds barrel and communicates with bore solely through plurality of passageways in barrel directly adjacent muzzle of tool so that high velocity gases produced upon ignition of explosive charge are directed into gas expansion chamber through passageways. Gas expansion chamber functions to receive and dissipate high velocity gases to thereby provide relatively silent operation of tool. Ejection structure associated with explosion chamber removes any spent explosive charges that remain after ignition.
    • 用于通过炸药的驱动元件的爆炸致动工具包括其中具有孔的筒,用于由工具驱动的定位元件。 枪口在枪管的一端设置,爆炸室与孔连通,用于接收打击乐器的可点燃爆炸物,由此当爆炸物被点燃时,位于孔内的元件由工具的枪口驱动。 闭合气体膨胀室围绕桶并且仅通过枪管中的多个通道直接与工具的枪口连通,使得在爆炸装药点火时产生的高速气体通过通道被引导进入气体膨胀室。 气体膨胀室用于接收和消散高速气体,从而提供工具相对无声的操作。 与爆炸室相关的喷射结构可消除点火后残留的任何乏燃料。
