    • The invention relates to a power drill, having a tool-clamping device that is fastened to a spindle shaft, having a torque clutch that includes an axially movable clutch plate on which an axial force is exerted by a plurality of compression springs that cooperate at least indirectly with an adjusting nut situated on a housing component. The compression springs are accommodated in first recesses embodied in the longitudinal direction of the housing component. A device for axially moving an axial bearing situated on the spindle shaft, is provided at the end of the spindle shaft oriented toward the tool-clamping device. According to the invention, on its side oriented toward the clutch plate, the device for axially moving the axial bearing has at least one actuating section that is situated in a second recess of the housing component and on the side oriented toward the clutch plate, cooperates with an adjusting element for the device.
    • 本发明涉及一种动力钻,其具有紧固到主轴上的工具夹紧装置,该工具夹紧装置具有扭矩离合器,该扭矩离合器包括可轴向移动的离合器板,多个压缩弹簧在其上施加有轴向力,所述多个压缩弹簧至少协调 间接地具有位于壳体部件上的调节螺母。 压缩弹簧容纳在壳体部件的纵向方向上实施的第一凹部中。 用于轴向移动位于主轴上的轴向轴承的装置设置在主轴轴向朝向工具夹紧装置的端部。 根据本发明,在朝向离合器片的侧面上,用于轴向移动轴向轴承的装置具有至少一个致动部分,其位于壳体部件的第二凹部中并且朝向离合器板的侧面上配合 具有用于该装置的调节元件。
