    • A “snap-in” bit chuck assembly for a rotary hand or powered tool, includes an elongated body having a hex shank at its rearward end, an elongated retraction collar slidably disposed on the body, and an outer retaining collar fixed to the forward end of the body. The body has a coaxial hex socket formed therein to allow a reversible tool to be inserted thereinto. A slot is formed in the body, between the outer surface of the body and the internal hex socket. A coil spring surrounds the body, inside the retraction collar, and normally biases the retraction collar forwardly and biases a retaining clip toward the bottom of the angular slot. The retaining clip slides outwardly in the angular slot, against the bias of the coil spring, as the reversible tool is inserted, where a recess on the reversible tool is engaged and retained by the clip. The tool is removed by sliding the retraction collar rearwardly, to compress the coil spring and allow the retaining clip to retract back up the slot. The clip is directly engaged by the coil spring and has two legs extending about the body so that the clip is self-retaining. The clip legs extend around the body such that the retraction force on the coil spring is directed through the center of the coil spring to keep it coaxially aligned with the body.
    • 用于旋转手或动力工具的“卡入式”卡盘组件包括在其后端具有六角柄的细长主体,可滑动地设置在主体上的细长缩回套环和固定到前端的外保持套环 的身体。 主体具有形成在其中的同轴六角形插座,以允许将可逆工具插入其中。 在主体的外表面和内六角插座之间形成一槽。 螺旋弹簧围绕主体,在收缩套环的内部,并且通常向前偏压缩回轴环,并将保持夹偏压到角槽的底部。 当可逆工具被插入时,保持夹在角槽中向外滑动,抵抗螺旋弹簧的偏压,其中可逆工具上的凹部被夹子接合并保持。 通过向后滑动收回环来移除该工具,以压缩螺旋弹簧并允许保持夹缩回到槽上。 夹子由螺旋弹簧直接接合,并且具有围绕主体延伸的两个腿,使得夹子是自固定的。 夹腿围绕身体延伸,使得螺旋弹簧上的缩回力被引导通过螺旋弹簧的中心以保持其与身体同轴对准。

    • A tool holder for releasably coupling a bit with a non-circular outer connector surface to a rotary driver. The tool holder includes a socket and a retaining mechanism coupled to the socket and operable in a retaining mode and a released mode. The socket includes a forward end with an opening extending rearwardly from the forward end. The opening also includes a non-circular cross-section adapted to receive the outer connector surface of the bit to couple the bit for rotation with the socket. The retaining mechanism is adapted to permit disposable of the bit into an operative position within the opening and to prevent axial movement of the bit out of its operative position when the retaining mechanism is in its retaining mode. The retaining mechanism is further adapted to permit axial displacement of the bit out of its operative position when the retaining mechanism is in its released mode. The retaining mechanism includes a sleeve coupled to the socket for displacement toward the forward end of the socket from a locked position to an unlocked position thereby moving the retaining mechanism from its retaining mode into its released mode. The retaining mechanism also includes a spring biasing the sleeve into its locked position.
    • 用于将钻头与非圆形外部连接器表面可释放地联接到旋转驱动器的工具保持器。 工具架包括一个插座和一个联接到插座的保持机构,可在保持模式和释放模式下操作。 插座包括从前端向后延伸的开口的前端。 开口还包括适于接收钻头的外连接器表面的非圆形横截面,以将钻头与插座连接以旋转。 保持机构适于允许钻头的一次性在开口内的操作位置,并且当保持机构处于其保持模式时,防止钻头的轴向运动脱离其工作位置。 保持机构还适于当保持机构处于其释放模式时允许钻头的轴向位移到其工作位置之外。 保持机构包括联接到插座的套筒,用于朝着插座的前端从锁定位置移动到解锁位置,从而将保持机构从其保持模式移动到其释放模式。 保持机构还包括将套筒偏压到其锁定位置的弹簧。
