    • A hammer drill for performing percussive drilling or rotary drilling includes a housing and a tool holder mounted on and axially displaceable relative to the housing, the tool holder contains a retainer sleeve mounting locking member for securing the shank of a tool in the holder. When the hammer drill is used only for rotary drilling, the retainer sleeve is displaced into contacting engagement with the housing for centering the tool holder. The tool holder includes stops for securing the locking members against axial displacement during rotary drilling. One stop is movable relative to the retainer sleeve and can be locked in position. Another stop forms part of the retainer sleeve. The stops combine with the closed ends of the recesses in the tool shank for holding the locking members against axial displacement.
    • 用于进行冲击钻孔或旋转钻孔的锤钻包括安装在壳体上并可相对于壳体轴向移位的壳体和工具夹具,工具夹具包括用于将工具的柄固定在保持器中的保持器套筒安装锁定构件。 当锤钻仅用于旋转钻孔时,保持器套筒被移位成与壳体接触接合,以使工具夹具居中。 工具架包括用于在旋转钻孔期间固定锁定构件以防止轴向位移的止动件。 一个止动件可相对于保持器套筒移动并且可以锁定就位。 另一个止挡形成保持套的一部分。 止动件与工具柄中的凹部的封闭端部结合,用于保持锁定构件抵抗轴向位移。
