    • A router table assembly includes a removable throat plate having a frame with a generally-planar upper surface, and an opening formed in the frame's upper surface. A disc, supported within the opening for rotation about a first axis, includes a through-hole which is sized to permit extension therethrough of a routing bit along a second axis parallel to the first axis. A graduated scale on the frame adjacent to the disc cooperates with a reference mark on the disk to provide an indication of the displacement of the bit's second axis relative to a reference edge on the working surface. A clamp secures the disc against rotation after the disc has been rotated within the frame to position the bit's second axis a desired distance from the reference edge. A fence is secured in one of a plurality of parallel-spaced positions relative to the reference edge.
    • 路由器台组件包括具有大致平面的上表面的框架的可拆卸的喉板和形成在框架的上表面中的开口。 支撑在开口内围绕第一轴线旋转的圆盘包括通孔,该通孔的尺寸设计成允许沿着平行于第一轴线的第二轴线延伸通过路线钻头。 在与盘相邻的框架上的刻度尺与盘上的参考标记协调,以提供钻头的第二轴相对于工作表面上的参考边缘的位移的指示。 在盘已经在框架内旋转之后,夹具将盘保持在不旋转的位置,以将钻头的第二轴定位到距参考边缘所需的距离。 围栏相对于参考边缘固定在多个平行间隔位置之一中。

    • A trigger mechanism for a portable electric power tool which can be selectively oriented in one of three states being a Locked-off, an On, and a Locked-on state. The trigger mechanism includes a trigger having a first latch portion and an actuator for actuating a switch for energizing a motor, a lock button having a second latch portion, a latch return spring, and a lock button return spring. The trigger is shiftable longitudinally between a Trigger-off and a Trigger-on position, while the lock button is shiftable transversely between a Button-off and a Button-on position. When the trigger mechanism is in the Locked-off state, the lock button is in the Button-off position preventing the trigger from moving from the Trigger-off position. When the trigger mechanism is in the On state, the lock button has been shifted to the Button-on position so that the trigger is shiftable to the Trigger-on position thereby actuating the switch. When the trigger mechanism is in the Locked-on state, the operator positions the first latch portion so that by releasing the trigger while in the On state the first and second latch portions engage.
    • 一种用于便携式电动工具的触发机构,其可以选择性地定向为处于锁定状态,开启状态和锁定状态的三种状态之一。 触发机构包括触发器,该触发器具有第一闩锁部分和用于致动用于激励电动机的开关的致动器,具有第二闩锁部分的锁定按钮,闩锁复位弹簧和锁定按钮复位弹簧。 触发器在触发和触发位置之间纵向移动,而锁定按钮可在按钮关闭和按钮开启位置之间横向移动。 当触发机构处于锁定状态时,锁定按钮处于按钮关闭位置,防止触发器从触发关闭位置移动。 当触发机构处于“打开”状态时,锁定按钮已被移动到按钮开启位置,以便触发器可移动到触发器位置,从而启动开关。 当触发机构处于锁定状态时,操作员将第一闩锁部分定位,使得通过在处于处于处于处于接通状态的触发状态下释放触发器来使第一和第二闩锁部分接合。
