    • A reciprocating saw (10) is provided having a motor oriented within a housing (14) for operably driving a saw bar (22) and blade holder (24) in a reciprocating motion. The blade holder (24) has a longitudinal slot (30) for receiving a saw blade (32), and a transverse aperture (36) extending into the longitudinal slot (30) for receiving a follower (38). A sleeve (42) is pivotally mounted upon the body (26), and has a circum-axial cam groove (46) formed therein cooperating with the follower (38). Rotation in a first lock direction urges the follower (38) into the longitudinal slot (30) for engaging the saw blade (32) and rotation of the sleeve (42) in a second unlock direction allows the follower (38) to retract. A biasing member (48) is included for biasing the sleeve (42) in the first lock direction. The sleeve central bore (44) is adapted to provide clearance for the follower (38) such that the sleeve (42) is permitted to axially translate relative to the body (26) for assembly or disassembly of the blade holder (24).
    • 一个往复锯(10),提供了一种具有用于可操作地驱动往复运动的锯栏(22)和刀片保持器(24)的壳体(14)内取向的马达。 所述刀片保持件(24)具有用于接纳锯片(32)的纵向槽(30),和一个横向孔(36)延伸进入用于接收一个从动件(38)的纵向槽(30)。 套筒(42)可枢转地安装在所述主体(26),并具有circum轴向凸轮槽(46)具有在其中形成的从动件(38)配合。 旋转在第一方向上推动锁定从动件(38)成用于接合所述锯片(32)和旋转套筒(42)的纵向槽(30)缩回的第二方向解锁允许该跟随器(38)。 偏置构件(48)被包括用于偏压在第一锁定方向上的套筒(42)。 所述套筒中心孔(44)是angepasst以提供用于从动件(38)的间隙检测所做的套筒(42)被允许轴向平移相对于主体(26),用于所述刀片保持件(24)的组装或拆卸。
