Abstract

A rotary tool ( 10 ) having a plurality of switchable modes is provide with a trigger ( 19 ) and a switching lever ( 20 ) disposed around a grip ( 13 ) for selecting a rotational direction of a motor ( 31 ). The switching lever ( 20 ) is operated between a forward rotation state, a reverse rotation state, and a neutral state. A switching of the modes is executed when the switching lever ( 20 ) is positioned in the neutral state and the trigger ( 19 ) is pulled.

First claim

What is claimed is:

1. A rotary tool having a plurality of switchable modes, the rotary tool comprising:
a motor;
a trigger;
a power source switch that turns on a power source of the rotary tool when the trigger is pulled to a predetermined position;
a rotation control switch which rotates the motor when the trigger is pulled over the predetermined position; and
a switching lever disposed around a grip to determine a rotational direction of the motor,
wherein the switching lever is operated between a forward rotation state of forwardly rotating the motor, a reverse rotation state of reversely rotating the motor, and a neutral state which is neither the forward rotation state nor the reverse rotation state, and
wherein a switching of the modes is executed when the switching lever is positioned in the neutral state and the trigger is pulled.

2. The rotary tool according to claim 1 , wherein switching of the modes is executed:
when the trigger is pulled to the predetermined position in the neutral state of the switching lever and a signal is generated on the power source switch; or
when the trigger is pulled over the predetermined position in the neutral state of the switching lever and a signal is generated on the rotation control switch.

3. The rotary tool according to claim 1 , wherein a rotation mode of the motor is changed by switching the modes.

4. The rotary tool according to claim 1 , further comprising an illumination unit that illuminates a driving position,
wherein an illumination condition of the illumination unit is changed by switching the modes.

5. The rotary tool according to claim 1 , further comprising a mode setting button,
wherein the trigger is disposed at a position to be operable by an index finger of a hand holding the grip,
wherein the switching lever is disposed at a position to be operable by a thumb or the index finger of the hand holding the grip portion, and
wherein the switching of the modes is executed not only by the pulling operation of the trigger in the neutral state of the switching lever but also by an operation of the mode setting button.

6. The rotary Tool according to claim 5 , wherein the motor rotates in a determined rotating direction and in a switched mode.
