    • 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。

    • A portable, hand-operated trimmer has a head module that is removably connected to a power control module. The head module has a power head enclosing an electric motor that is operatively connected to a trimming blade. The power head is selectably settable in a plurality of angular positions with respect to a head support, including a neutral position representing 0 degree rotation, 45 degree flexion and dorsiflexion positions, and 90 degree flexion and dorsiflexion positions. The power head also encloses a stator cartridge that is connected to the housing of the power head by a plurality of fastening members. The head support rotates about the stator cartridge and is engaged by way of a movable engagement pin that is received within a selected recess defined in the stator cartridge. The power head housing and stator cartridge further define molded sockets to receive corresponding pivot arms of the head support. An O-ring is disposed about one of the pivot arms to dampen free rotation. The power control module provides power to the power head through a removable rechargeable battery or through direct connection to conventional household power.
    • 便携式手动修剪器具有可移除地连接到电源控制模块的头模块。 头模块具有包围可操作地连接到修剪刀片的电动机的动力头。 动力头可选择地设置在相对于头部支撑件的多个角度位置中,包括表示0度旋转,45度屈曲和背屈位置的中立位置以及90度屈曲和背屈位置。 动力头还包围定子盒,该定子盒通过多个紧固构件连接到动力头的壳体。 头部支撑件围绕定子盒旋转,并通过可移动的接合销接合,该可动接合销被容纳在限定在定子盒中的所选择的凹部内。 动力头壳体和定子筒进一步限定模制插座以接收头部支撑件的相应枢转臂。 O形环围绕其中一个枢转臂设置以阻止自由旋转。 电源控制模块通过可拆卸的可再充电电池或通过直接连接到常规家用电源为电源头提供电源。
