Abstract
A power tool includes a motor disposed in a motor housing, a handle extending downward from the motor housing, a main switch provided on the handle and configured to switch the motor ON and OFF, and a state-changing operation part located on a lower portion of the motor housing or on an upper-end portion of the handle. The state-changing operation part is located upward of the main switch and is configured to effect a change of a rotational state of the motor, other than a direction of rotation of the motor, or an illumination level of a light.
Claims25
A power tool comprising:
- a main housing;
- a motor disposed in the main housing;
- a controller configured to control operation of the motor;
- a handle extending obliquely from the main housing;
- a trigger that is depressible to energize the motor, the trigger being disposed on the handle between a first portion of the handle that connects to the main housing and a second portion of the handle that is remote from the first portion of the handle;
- a first button located on the main housing adjacent to the handle or on the first portion of the handle, the first button being configured to depress a first switch that is electrically connected with the controller and being disposed in a plane that intersects the trigger, the first portion of the handle and the second portion of the handle so as to be operable by a finger of a user's hand while the user is gripping the handle, the first button being pressable to cycle through and manually select one impact force setting from among a plurality of stored impact force settings solely by a single push of the first button;
- and
- a second button located on the second portion of the handle, the second button being configured to depress a second switch that is electrically connected with the controller and being pressable to cycle through and manually select one impact force setting from among the plurality of stored impact force settings.

- a trigger that is depressible to energize the motor, the trigger being disposed on the handle between a first portion of the handle that connects to the main housing and a second portion of the handle that is remote from the first portion of the handle;
- an impact-force pushbutton switch located in the second portion of the handle, the impact-force pushbutton switch being electrically connected with the controller and configured to manually select one impact force setting from among a plurality of stored impact force settings with each pressing of the impact-force pushbutton switch;
- an automatic-speed-changing mode pushbutton switch located in the second portion of the handle and configured to output a signal to the controller that selects one automatic-speed-changing mode from a plurality of automatic-speed-changing modes or cancels the selection of a previously selected automatic-speed-changing mode;
- and
- a state-setting pushbutton switch located on the main housing adjacent to the handle or on the first portion of the handle and being disposed in a plane that intersects the trigger, the first portion of the handle and the second portion of the handle so as to be operable by a finger of a user's hand while the user is gripping the handle, the state-setting pushbutton switch being pressable to cycle through the plurality of stored impact force settings in response to each press of the state-setting pushbutton switch.

A power tool comprising:
- a motor;
- a spindle operably coupled to the motor and extending in a front-rear direction;
- a main housing that accommodates the motor and is elongated in the front-rear direction;
- a handle portion extending from the main housing obliquely with respect to the front-rear direction;
- a switch main-body part provided in an upper portion of the handle portion;
- a trigger provided forward of the switch main-body part in the front-rear direction and being depressible rearward in the front-rear direction to change a state of the switch main-body part;
- a state-switch transmitting part provided in the main housing or in the handle portion between the trigger and the spindle in an up-down direction that is perpendicular to the front-rear direction;
- a state-switching button provided forward of the state-switch transmitting part in the front-rear direction and being depressible rearward in the front-rear direction to change a switch state of the state-switch transmitting part;
- and
- a controller electrically connected to the switch main-body part and to the state-switch transmitting part, the controller being configured to change a currently-selected impact force that is applied to the spindle in response to each change of the switch state of the state-switching button.
