Power tool
A power tool includes a grip, a connecting part, an elastic element, an electrical switch and an operating member. The connecting part connects the grip to the power tool body. The elastic element is disposed between the connecting part and the power tool body. The operating member is switched by a user between an energizing position and a de-energizing position. The operating member is retained in the position to which it is switched. The operating member is disposed in the connecting part in such a manner as to be slidable in a direction transverse to the longitudinal direction of the power tool body and to the extending direction of the grip.
1. A hand-held power tool which performs a predetermined operation on a workpiece by a tool bit disposed in a tip end region of a power tool body and driven by a motor comprising:
a grip arranged on the proximal end of the power tool body from the tool bit, the grip extending in a direction transverse to an axis parallel to the tool bit,
a connecting part that connects the grip to the power tool body at one end of the grip,
an elastic element disposed between the connecting part and the power tool body, the elastic element reducing transmission of vibration from the power tool body to the grip,
an electrical switch that switches the motor between an energized state and a de-energized state and
an operating member with a substantially V-shaped portion, the operating member being configured to be switched by a user between an energizing position in which the electrical switch switches the motor to the energized state and a de-energizing position in which the electrical switch switches the motor to the de-energized state, the operating member being retained in the position to which it is switched, wherein:
the operating member is disposed in the connecting part in such a manner as to be slidable in a direction transverse to the axis parallel to the tool bit and an axis approximately parallel to the grip,
the substantially V-shaped portion engages the electrical switch to move the electrical switch between the energized state and the de-energized state when the operating member is operated,
the operating member is retained in the position to which the operating member is switched without external force being applied, and
the electrical switch is located in the grip and rearward of the elastic element.
2. The power tool as defined in claim 1 , wherein the grip is hollow and the electrical switch is disposed in a hollow part of the grip.
3. The power tool as defined in claim 1 , wherein the grip is connected to the power tool body at the other end side in the extending direction of the grip in such a manner as to be rotatable on a pivot with respect to the power tool body in the longitudinal direction of the power tool body.
4. The power tool as defined in claim 3 , wherein a motor control unit is disposed on the power tool body side, and the electrical switch and the motor control unit are connected by a wire running to the power tool body side through the grip at the other end side in the extending direction of the grip.
5. The power tool as defined in claim 1 , wherein the operating member is retained in the position to which the operating member is switched by frictional resistance.
6. The power tool as defined in claim 1 , wherein the direction transverse to the longitudinal direction of the power tool body is approximately perpendicular to the longitudinal direction of the power tool body and to the extending direction of the grip.
7. The power tool as defined in claim 1 , wherein the operating member is disposed in the connecting part in such a manner as to be linearly slidable in the direction transverse to the longitudinal direction of the power tool body and to the extending direction of the grip.
8. The power tool as defined in claim 1 , wherein the electrical switch is the only switch configured to be actuated by a user to switch the motor to the energized state or the de-energized state.
