    • A hand saw that includes a saw blade and a handle assembly having a clamp member movable between a clamped position and a released position. In the clamped position the clamp member exerts a clamping force on a top edge of the saw blade within a slot of the handle assembly to couple the saw blade to the handle assembly and to retain a tang of the saw blade within the slot. In the released position the tang is removable from the slot. A first interior wall and a second interior wall of the handle assembly that define the slot are flat such that the tang of the saw blade can be removed from the slot without moving the saw blade in a direction normal to a longitudinal axis of the saw blade when the clamp member is in the released position.
    • 一种手锯,其包括锯片和具有可在夹紧位置和释放位置之间移动的夹紧构件的手柄组件。 在夹紧位置,夹紧构件在手柄组件的狭槽内在锯片的顶部边缘上施加夹紧力,以将锯片联接到手柄组件并且将锯片的柄脚保持在狭槽内。 在释放位置,脚可从插槽中移除。 限定狭槽的手柄组件的第一内壁和第二内壁是平坦的,使得锯片的柄脚可以从狭槽移除,而不会沿着垂直于锯片的纵向轴线的方向移动锯片 当夹紧构件处于释放位置时。

    • An impact tool includes a housing, a motor supported in the housing, an output shaft rotatably supported in the housing about a central axis, an impact mechanism coupled between the motor and the output shaft and operable to impart a striking rotational force to the output shaft, and a clutch mechanism coupled between the impact mechanism and the output shaft. The clutch mechanism is operable in a first mode, in which torque from the motor is transferred to the output shaft through the impact mechanism, and a second mode, in which torque from the motor is diverted from the output shaft toward a portion of the impact mechanism.
    • 冲击工具包括壳体,支撑在壳体中的马达,围绕中心轴线可旋转地支撑在壳体中的输出轴;联接在马达和输出轴之间的冲击机构,其可操作以向输出轴施加醒目的旋转力 以及联接在冲击机构和输出轴之间的离合器机构。 离合器机构可以在第一模式中操作,其中来自马达的扭矩通过冲击机构传递到输出轴;第二模式,其中来自马达的扭矩从输出轴转向冲击部分 机制。

    • A cutting tool clamp mechanism for a power tool includes a housing supported by a spindle, the spindle being configured to receive and drive a cutting tool along a longitudinal axis of the spindle. A clamping system is supported by the housing and includes an engaging portion movable relative to the spindle, the clamping system having an engaged condition, in which the engaging portion is engageable with the cutting tool to secure the cutting tool in the spindle, and a released condition, in which the engaging portion is disengageable with the cutting tool. A biasing member is positioned between the housing and the clamping system, and operable to bias the clamping system to the engaged condition. When the cutting tool is removed from the spindle, the clamping system is held in the released condition, and upon insertion of the cutting tool into the housing, the clamping system moves from the released condition to the engaged condition.
    • 用于电动工具的切割工具夹紧机构包括由主轴支撑的壳体,所述主轴被构造成沿主轴的纵向轴线接收和驱动切割工具。 夹紧系统由壳体支撑并且包括可相对于主轴移动的接合部分,夹紧系统具有接合状态,其中接合部分可与切割工具接合以将切割工具固定在主轴中,并且释放 条件,其中接合部分可与切割工具脱离接合。 偏压构件定位在壳体和夹紧系统之间,并且可操作以将夹紧系统偏压到接合状态。 当切割工具从主轴移除时,夹紧系统保持在释放状态,并且当将切削工具插入壳体中时,夹紧系统从释放状态移动到接合状态。
