    • A movable handle and a power tool. The power tool comprises a housing, a motor supported by the housing and operable to drive a tool element about an axis, and a handle supported by the housing for rotation relative to the housing about the axis. Preferably, the power tool is a circular saw. The circular saw further comprises a switch assembly supported on the handle for movement with the handle and means for connecting the switch to the motor to accommodate movement of the switch relative to the motor. The switch assembly is electrically connectable to the motor and selectively connects the motor to a power source, and the connecting means includes a wiring arrangement. The circular saw further comprises a locking assembly for locking the handle in a position relative to the housing. Also, the circular saw preferably comprises means for preventing the switch assembly from connecting the motor to the power source when the locking assembly is in the unlocked condition and means for preventing the locking assembly from being operated from the locked condition to the unlocked condition when the switch assembly is in the operated condition.
    • 可移动手柄和电动工具。 电动工具包括壳体,由壳体支撑并且可操作以围绕轴线驱动工具元件的电动机和由壳体支撑的手柄,用于相对于壳体围绕轴线旋转。 优选地,电动工具是圆锯。 圆锯进一步包括支撑在手柄上用于与手柄一起移动的开关组件和用于将开关连接到马达的装置,以适应开关相对于马达的运动。 开关组件可电连接到电动机并且选择性地将电动机连接到电源,并且连接装置包括布线装置。 圆锯进一步包括用于将手柄锁定在相对于壳体的位置的锁定组件。 此外,圆锯优选地包括用于当锁定组件处于未锁定状态时防止开关组件将电动机连接到电源的装置,以及用于防止锁定组件从锁定状态操作到未锁定状态的装置, 开关组件处于工作状态。

    • Carrying systems, connecting systems and methods. The system connects a power tool and a component. In some constructions and in some aspects, the power tool includes a housing and a U-shaped receptacle defined by the housing. In some constructions and in some aspects, the component includes a stud selectively engageable with the receptacle to connect the power tool and the component. A locking mechanism is positioned within the receptacle and includes a cam. The locking mechanism is engageable with the stud to restrict movement of the stud with respect to the receptacle. The stud includes a recess at an end of the stud. The cam is selectively engageable with the recess to retain the stud within the receptacle. The cam is movable between a lock position and a released position. In the locked position, the cam extends into the recess and engages the stud. In the released position, the cam is retracted from the recess and is disengaged with the stud.
    • 携带系统,连接系统和方法。 系统连接电动工具和组件。 在一些结构中,并且在一些方面,电动工具包括壳体和由壳体限定的U形插座。 在一些结构中并且在一些方面,该部件包括可选择性地与插座接合以连接电动工具和部件的螺柱。 锁定机构位于容器内并包括凸轮。 锁定机构可与螺栓接合以限制螺柱相对于容器的移动。 螺柱包括在螺柱的端部处的凹部。 凸轮可选择性地与凹部接合,以将螺柱保持在容器内。 凸轮可在锁定位置和释放位置之间移动。 在锁定位置,凸轮延伸到凹槽中并接合螺柱。 在释放位置,凸轮从凹部缩回并与螺柱脱离。
