    • A tool with a transmission assembly having a reduction gearset and a speed selector. The speed selector has a member, an actuator and a shifter assembly. The member is movable between a first position, in which the member is non-rotatable, and a second position in which the member is coupled to a planet carrier of the reduction gearset for common rotation. The actuator includes a pivoting yoke and a follower that is coupled to the yoke. The follower engages the member so as to be axially movable with the follower. The shifter assembly has a selector switch, a switch fork, and a pair of springs. The selector switch is slidable between a first switch position and a second switch position. The shift fork is slidably coupled to the selector switch and receives the yoke. The springs cooperate to bias the shift fork relative to the selector switch into a neutral position.
    • 具有变速器组件的工具具有减速齿轮组和速度选择器。 速度选择器具有构件,致动器和换档器组件。 该构件可在第一位置和第二位置之间移动,在第一位置,构件不可转动,第二位置与构件联接到用于共同旋转的减速齿轮组的行星架。 致动器包括枢转轭和联接到轭的跟随器。 从动件与构件接合,以便与跟随器可轴向移动。 换档器组件具有选择开关,开关叉和一对弹簧。 选择器开关可在第一开关位置和第二开关位置之间滑动。 换档拨叉可滑动地连接到选择器开关并接收轭架。 弹簧配合以将换档拨叉相对于选择器开关偏压到中立位置。

    • A reciprocating saw can include a housing and a motor disposed in the housing. A blade retaining mechanism can receive a saw blade. A drive mechanism can translate rotational motion of the motor into reciprocating motion of the blade retaining mechanism. A clamp assembly can include first and second shoes that are coupled to the housing. The first shoe can have a first shoe body that includes a first material facing surface. The second shoe can include a second material facing surface that opposes the first material facing surface and that defines a clamping distance therebetween. At least one of the first and second shoes is selectively adjustable relative to the housing, such that the clamping distance can be altered. One of the first or second shoe bodies can have a third material facing surface that comprises an arcuate section defining a radius.
    • 往复锯可以包括设置在壳体中的壳体和马达。 刀片保持机构可以接收锯片。 驱动机构可将马达的旋转运动转换成刀片保持机构的往复运动。 夹具组件可以包括联接到壳体的第一和第二鞋。 第一鞋可以具有包括面向第一材料的第一鞋体。 第二鞋可以包括与面向第一材料的表面相对并且在其之间限定夹紧距离的面向第二材料的表面。 第一和第二鞋中的至少一个相对于壳体可选择性地调节,使得可以改变夹紧距离。 第一或第二鞋体之一可以具有面向第三材料的表面,其包括限定半径的弓形部分。
