    • A power tool with a flywheel, an activation arm, a driver, a cam and a clutch. The activation arm can have a first arm, a second arm, which can be pivotally mounted to the first arm, and a roller that can be coupled to the second arm. The driver can be disposed between the roller and the flywheel. The cam can be moveable in a predetermined direction for causing the activation arm to rotate about a pivot to drive the roller against the driver so that the driver frictionally engages the flywheel. The clutch can cooperate with the cam to inhibit the cam from moving in a direction opposite the predetermined direction in response to a reaction force that is applied by the driver onto the activation arm.
    • 具有飞轮,激活臂,驾驶员,凸轮和离合器的电动工具。 激活臂可以具有第一臂,第二臂,其可以枢转地安装到第一臂,以及可以联接到第二臂的辊。 驾驶员可以设置在滚轮和飞轮之间。 凸轮可以沿预定方向移动,以使致动臂围绕枢轴旋转,以驱动辊抵靠驾驶员,使得驾驶员摩擦地接合飞轮。 离合器可以与凸轮配合,以响应于由驾驶员施加到激活臂上的反作用力而使凸轮沿与预定方向相反的方向移动。

    • A hand-held power tool with a housing with a handle arranged along an axis, a trigger disposed in the housing and configured to operate the hand-held power tool, first and second sets of guide tracks coupled to one of the housing and the trigger and first and second sets of guides coupled to the other. The trigger, which includes a contact surface that is configured to be contacted by a finger of a user of the hand-held power tool, is movable between an extended position and a retracted position. The first and second sets of guide tracks guide the first and second sets of guides, respectively, such that movement of the trigger from the extended position to the retracted position causes the contact surface to move in a substantially constant direction having a first directional component and a second directional component, the first directional component being generally perpendicular to the axis of the handle and the second directional component being generally parallel to the axis of the handle.
    • 一种手持式电动工具,其具有沿着轴线布置的手柄的壳体,设置在所述壳体中并构造成操作所述手持式电动工具的触发器,所述第一和第二组导轨耦合到所述壳体和所述触发器之一 以及耦合到另一组的第一和第二组引导件。 触发器,其包括构造成由手持式电动工具的使用者的手指接触的接触表面,可在延伸位置和缩回位置之间移动。 第一和第二组导轨分别引导第一组和第二组导向件,使得触发器从伸出位置到缩回位置的运动使得接触表面沿着具有第一方向分量的基本上恒定的方向移动,并且 第二方向分量,第一方向分量大致垂直于手柄的轴线,第二方向分量大致平行于手柄的轴线。
