    摘要： A hand held circular saw for a portable circular saw 10 in which a viewing cutout 34 is provided through the housing 12 between an electric motor 14 and a blade guard support member 19. A transparent chip shield 32 is attached to the housing 12 and is pivotable between an operating position covering the viewing aperture and a raised cleaning position. In the preferred embodiment, notch engaging bosses 48 provided on the chip shield engage notches 50 in the housing 12 to snap lock the chip shield in the operating position.

    摘要： A power tool is provided which includes a shaft rotatably driven by the motor and an axial lining in the central bore of the working element. A counterweight assembly is attached to the shaft for rotation therewith. A post on the counterweight assembly is insertable in the axial lining. A detent is mounted to the post and includes arcuate cam surfaces. The detent is movable between (1) an extended position relative to the post, and (2) a depressed position relative to the post wherein the axial lining engages the cam surfaces and allows the post to be inserted in the axial lining. A circumferential groove on the axial lining is capable of capturing the detent in the extended position to provide for substantially fail-safe operation of the tool with the post inserted in the axial lining.

    摘要： 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.

    摘要翻译： 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。
