摘要： An axially movable sleeve (36) has interference members or lugs (38) associated with the split nut (34) in a chuck. When the chuck is driven by the spindle (18), the axially movable interference members (38) engage the split nut interference members (40) and are restrained from rotation. The nut (34) is also restrained and the chuck jaws (30) open or close depending upon the direction of rotation of the chuck body (24). The sleeve (36) is positioned to be engaged by the jaws (30) as they approach the full open position. The jaws (30) then move the sleeve (36) axially to disengage the interference members (40, 38) and stop further opening of the jaws (30) before they reach a position to wedge or jam in the open position.
摘要翻译：轴向可移动的套筒（36）具有与夹头中的分离螺母（34）相关联的干涉构件或凸耳（38）。当卡盘由主轴（18）驱动时，轴向移动的干涉构件（38）与分离螺母干涉构件（40）接合并被限制旋转。螺母（34）也被限制，并且卡盘爪（30）根据卡盘主体（24）的旋转方向而打开或关闭。套筒（36）定位成在夹爪（30）接近完全打开位置时与夹爪（30）接合。然后，夹爪（30）轴向地移动套筒（36）以脱离干涉构件（40,38），并且在夹爪（30）到达打开位置之前楔入或阻塞的位置时停止进一步打开夹爪30。

摘要： A reciprocating saw (20) having a housing (22), a spindle (24) mounted for reciprocation within the housing, and a motor for reciprocating the spindle (24). A track member (56) is interconnected with the spindle to allow the spindle to be reciprocated in a down-cutting rocking motion, a non-rocking motion, or an up-cutting rocking motion. The spindle slides within a counterweight (26) and the counterweight slidably interacts with the track member (56). A hinged bearing (90) interconnects the drive arm (48) with the spindle (24). The wobble plate (44, 46) is mounted on a wobble shaft (42) rotatable about a rotating axis, and the hinged bearing includes a cylindrical member (96) mounted to the spindle for pivoting about a pivoting axis (100) that is substantially perpendicular to the rotating axis (110). The drive arm (48) reciprocates along a reciprocating axis (112) that is substantially perpendicular to the pivoting axis, and the cylindrical member (96) is slidable relative to the drive arm along a sliding axis that is substantially perpendicular to the pivoting axis.
摘要翻译：具有壳体（22）的活动锯（20），安装用于在壳体内往复运动的主轴（24）和用于使主轴（24）往复运动的马达。轨道构件（56）与主轴互连，以允许主轴在下切摇摆运动，非摇摆运动或向上切割摇摆运动中往复运动。主轴在配重（26）内滑动，并且配重与轨道构件（56）可滑动地相互作用。铰链轴承（90）将驱动臂（48）与主轴（24）互连。摆动板（44,46）安装在可围绕旋转轴线旋转的摆动轴（42）上，铰接轴承包括安装在心轴上的圆柱形构件（96），用于围绕枢转轴线（100）枢转，基本上垂直于旋转轴线（110）。驱动臂（48）沿着基本上垂直于枢转轴线的往复运动轴线（112）往复运动，并且圆柱形构件（96）可相对于驱动臂沿着基本上垂直于枢转轴线的滑动轴线滑动。

摘要： A reciprocating saw having a main body (12) and a spindle (16) mounted in the main body and movable between a retracted position and an extended position. The saw further includes a biasing member (56) operatively associated with the spindle (16). The biasing member (56) can include a spring that acts on an inner end of the spindle (16) to bias the spindle toward either the extended position or the retracted position.

摘要： A reciprocating saw comprising a reciprocatable spindle (44) having an end adapted to receive a saw blade (42), and a blade clamp mechanism (41) connected to the spindle (44) and adapted to attach the saw blade (42) to the spindle. The blade clamp mechanism (41) includes an actuating member (56) mounted on the end of the spindle (44), a locking member (50) operatively associated with the actuating member (56), and a biasing member (54) interconnected with the actuating member for biasing the actuating member toward an engaged position. A cover (52) encloses a substantial portion of the biasing member (54). A housing (59), made from a thermally insulative material, is mounted to the actuating member (56). An ejecting member (90) is interconnected with the spindle (44) and is capable of engaging the saw blade (42) such that the saw blade is urged away from the end of the spindle.
