    • A new and improved remote trigger actuating mechanism for a power tool comprises an elongated handle or pole which is provided with a handgrip upon a rear end portion, while a mounting bracket, into which a forward end portion of the elongated handle or pole is fixedly engaged, is fixedly mounted upon a rear end portion of the power tool as a result of being bolted directly thereto by suitable bolt fasteners. A spring-biased sleeve member is concentrically disposed about the elongated handle or pole, and a trigger actuator linkage member has a rear end portion thereof fixedly mounted upon the spring-biased sleeve member while a forward end portion of the trigger actuator linkage member is provided with a hooked portion which is adapted to engage the trigger mechanism of the power tool. The spring-biased sleeve member is normally biased to a forward extended position by a coil spring such that the trigger actuator linkage member does not normally engage the trigger mechanism of the power tool, however, when the spring-biased sleeve member is manually moved in the rearward direction against the spring-biasing force of the coil spring, the trigger actuator or linkage member will engage and actuate the trigger mechanism of the power tool whereby the power tool will be energized.
    • 一种用于电动工具的新的和改进的远程触发器致动机构包括细长手柄或杆,其在后端部分上设置有手柄,而安装支架,细长手柄或杆的前端部固定地接合到该支架中 由于通过合适的螺栓紧固件直接螺栓固定在电动工具的后端部上。 弹簧偏置的套筒构件围绕细长的把手或杆同心地设置,并且触发器执行器连接构件的后端固定地安装在弹簧偏置的套筒构件上,同时提供了触发器致动器连杆构件的前端部分 具有适于接合电动工具的触发机构的钩状部分。 弹簧偏置的套筒构件通常被螺旋弹簧偏压到向前延伸的位置,使得触发器致动器连杆构件通常不与动力工具的触发机构接合,然而,当弹簧偏压的套筒构件被手动地移动 反向螺旋弹簧的弹簧偏压力的向后方向,触发器致动器或联动构件将接合并致动动力工具的触发机构,由此动力工具将被通电。

    • In a fastener-driving tool having a reciprocating driver blade for driving fasteners into a workpiece, a magazine configured for storing and feeding at least one collated strip of fasteners to the driver blade, including a housing defining a feed end, a driving end and a guidance portion disposed between and contacting the two ends, the guidance portion having at least two guidance formations, a first guidance formation configured for engaging the fastener strip at a first location, and the second guidance formation configured for engaging the fastener strip at a second location. In a preferred embodiment, the fastener strip is supported only by the first guidance formation in a first zone of the magazine, and only by the second guidance formation is a second zone of the magazine.
    • 在具有用于将紧固件驱动到工件中的往复式驱动器刀片的紧固件驱动工具中,所述仓被构造用于存储并将至少一个成对的紧固件条带供给到所述驱动器刀片,包括限定进给端的壳体,驱动端和 所述引导部分设置在所述两个端部之间并且接触所述两个端部,所述引导部分具有至少两个引导结构,构造成用于在第一位置处接合所述紧固件条的第一引导部分,以及构造成用于在所述第二位置 。 在一个优选实施例中,紧固件条仅由钉仓的第一区域中的第一引导构件支撑,并且仅通过第二引导构件是钉仓的第二区域。
