Portable electrical power tool
A portable electric power tool including a housing having one end to which an L-shaped battery pack is installable. A motor is accommodated in the housing. A switch assembly includes a switch body installed in the housing. The switch body is overlapped with the L-shaped battery pack in a longitudinal direction of the power tool. The switch assembly further includes a trigger including a pivot portion, a manipulation portion extending frontward from the pivot portion and pivotally movable, and a lever portion extending rearward from the pivot portion to actuate the switch body. The manipulation portion is disposed to overlap with a center of gravity of an entire power tool in the longitudinal direction, and the pivot portion is positioned between the manipulation portion and the switch body.
1. A portable electric power tool including:
a housing having a hand-gripped portion extending in a longitudinal direction, the hand-gripped portion having one end portion in which a battery is installable;
a motor accommodated in the housing; and
a trigger provided at the hand-gripped portion and exposed to an atmosphere for access and operation, the trigger comprises a manipulation portion externally accessible and operable, a pivot portion supported to the hand gripped portion and pivotally movably supporting the manipulation portion, and a lever portion extending to the switch body from the manipulation portion via the pivot portion; and
a switch body positioned in the housing and configured to perform switching of an electrical power supply to the motor, characterized in that
the switch body is positioned to be overlapped with the battery in the longitudinal direction, and the trigger extends to the switch body.
2. The portable electric power tool as claimed in claim 1 , characterized in that the hand-gripped portion has another end portion in which the motor is accommodated.
3. The portable electric power tool as claimed in claim 1 , characterized in that the switch body comprises an ON/OFF switch, the ON/OFF switch and a part of the lever portion being positioned on an imaginary plane perpendicular to the longitudinal direction.
4. The portable electric power tool as claimed in claim 3 , characterized in that the ON/OFF switch is rendered ON by the lever portion in response to the operation of the manipulation portion.
5. The portable electric power tool as claimed in claim 4 , characterized in that the ON/OFF switch provides a ON direction perpendicular to a moving direction of the lever portion.
6. The portable electric power tool as claimed in claim 1 , characterized in that the switch body comprises a speed change switch for changing a rotation speed of the motor, the speed change switch and a part of the lever portion being positioned on an imaginary plane perpendicular to the longitudinal direction.
7. The portable electric power tool as claimed in claim 6 , characterized in that the speed change switch is operated by the lever portion in response to the operation of the manipulation portion.
8. The portable electric power tool as claimed in claim 6 , wherein the speed change switch provides a speed changing direction parallel to a moving direction of the lever portion.
