    • A reciprocating saw includes a housing assembly and a motor positioned substantially within the housing assembly. The motor includes a pinion. A drive mechanism is positioned substantially within the housing assembly and includes a gear driven by the pinion, a spindle, and a connecting rod to transmit rotation of the gear into reciprocation of the spindle. A bushing is positioned substantially within the housing assembly about at least a portion of the spindle. The bushing is pivotable relative to the housing assembly to accommodate non-linear rocking motion of the spindle. A seal surrounds a portion of the bushing and includes a first lip extending radially from the bushing and a second lip spaced apart from the first lip and extending radially from the bushing. The second lip is movable relative to the first lip. Both the first lip and the second lip continuously engage the housing assembly when the bushing pivots relative to the housing assembly.
    • 往复锯包括壳体组件和基本上位于壳体组件内的马达。 马达包括一个小齿轮。 驱动机构基本上位于壳体组件内,并且包括由小齿轮驱动的齿轮,心轴和连接杆,以将齿轮的旋转传递到心轴的往复运动。 衬套围绕主轴的至少一部分基本上位于壳体组件内。 衬套相对于壳体组件可枢转以适应主轴的非线性摇摆运动。 密封件围绕套管的一部分并且包括从衬套径向延伸的第一唇缘和与第一唇缘间隔开并从衬套径向延伸的第二唇缘。 第二唇缘相对于第一唇缘是可移动的。 当衬套相对于壳体组件枢转时,第一唇缘和第二唇缘都连续接合壳体组件。

    • A saw blade clamping arrangement for a power tool including a housing, a drive shaft mounted for reciprocating motion relative to the housing and having a longitudinal drive axis, and a saw blade releasably interconnected with the drive shaft. The saw blade clamping arrangement includes a blade support mechanism with first and second slots crosswise intersecting slots configured to selectively receive the saw blade in first and second orientations. The clamping arrangement also includes a tubular actuator rotatable about the longitudinal drive axis between an engaged position and a disengaged position, the actuator including a locking cam surface, and a locking member operatively associated with the actuator, and movable between a locked position that selectively locks the blade in one of the first and second orientations and an unlocked position that releases the blade, the locking member including a follower surface driven by the locking cam surface.
    • 一种用于电动工具的锯片夹持装置,包括壳体,安装成相对于壳体往复运动并具有纵向驱动轴线的驱动轴以及与驱动轴可释放地互连的锯片。 锯片夹持装置包括刀片支撑机构,其具有第一和第二槽,横向相交的槽构造成在第一和第二取向中选择性地接收锯片。 所述夹紧装置还包括可在接合位置和脱离位置之间围绕所述纵向驱动轴线旋转的管状致动器,所述致动器包括锁定凸轮表面和与所述致动器可操作地相关联的锁定构件,并且可在锁定位置和锁定位置之间移动, 所述刀片处于所述第一和第二取向中的一个以及释放所述刀片的解锁位置,所述锁定构件包括由所述锁定凸轮表面驱动的从动表面。
