Abstract
A reducer appropriately selects from three or more variable speeds to match multiple operational modes. An impact driver includes a motor, a reducer that reduces rotation from the motor to select from three or more variable speeds, a plurality of actuators to be actuated by the rotation reduced by the reducer, and a switcher that selects, from the plurality of actuators, a specific actuator to be actuated in a predetermined operational mode. The switcher causes the reducer to cooperate with the selected specific actuator and actuates the reducer at a predetermined variable speed of the three of more variable speeds corresponding to the predetermined operational mode of the selected specific actuator.
Claims6
An impact tool, comprising:
- a motor;
- a motor housing accommodating the motor;
- a grip extending downward from the motor;
- a hammer configured to be rotated by the motor;
- an anvil configured to be struck by the hammer in a rotation direction;
- a hammer case accommodating the hammer;
- a spring configured to urge the hammer frontward;
- a guard located in front of the grip, the guard extending downward from the motor housing or the hammer case, the guard internally having a wiring housing;
- a battery mount connected to a lower end of the grip and a lower end of the guard, the battery mount configured to receive a battery pack;
- a light disposed in a front portion of the hammer case, the light configured to illuminate a distal end of the anvil;
- and
- a lead wire disposed in the wiring housing, the lead wire electrically connected to the light.
A screwing tool, comprising:
- a motor;
- a motor housing accommodating the motor;
- a grip extending downward from the motor;
- a reducer configured to reduce rotation from the motor;
- a tool holding portion configured to be driven by the reducer;
- a guard located in front of the grip, the guard extending downward from the motor housing or the reducer, the guard internally having a wiring housing;
- a battery mount connected to a lower end of the grip and a lower end of the guard, the battery mount configured to receive a battery pack;
- a light disposed in a front portion of the reducer, the light configured to illuminate a distal end of the tool holding portion;
- and
- a lead wire disposed in the wiring housing, the lead wire electrically connected to the light.
