Driver drill
A driver drill allows smooth change of the drive conditions of a motor. The driver drill includes a motor, an output unit located frontward from the motor and rotatable with a rotational force from the motor, a trigger lever operable to activate the motor, a forward-reverse switch lever operable to change a rotation direction of the motor, a first operation member operable to change a drive condition of the motor, a second operation member located upward from the first operation member and operable to change the drive condition of the motor, and a controller that sets the drive condition of the motor in response to an operation on at least one of the first operation member or the second operation member.
1. A driver drill, comprising:
a motor;
a motor compartment housing the motor;
an output unit in front of the motor and rotatable with a rotational force from the motor;
a grip extending downward from the motor compartment;
a trigger lever (i) operable to activate the motor and (ii) on the grip;
a battery holder below the grip;
a forward-reverse switch lever (i) operable to change a rotation direction of the motor and (ii) on an upper portion of the grip;
a dial operable to change a torque threshold for the motor;
a push switch (i) above the dial, (ii) being operable to change the torque threshold, and (iii) on the motor compartment; and
a controller configured to stop the motor when a torque of the motor exceeds the torque threshold.
2. The driver drill according to claim 1 , wherein
the controller is configured to control a time for the motor to stop after the torque of the motor exceeds the torque threshold.
3. The driver drill according to claim 1 , wherein
the push switch and the controller are configured such that a single push on the push switch changes the torque threshold by a predetermined value.
4. The driver drill according to claim 3 , wherein the push switch, the controller and the forward-reverse switch are configured such that
pushing the push switch with the forward-reverse switch lever in a first operational state increases the torque threshold, and
pushing the push switch with the forward-reverse switch lever in a second operational state decreases the torque threshold.
5. The driver drill according to claim 4 , wherein
the forward-reverse switch lever and the push switch are at least partially at a same height.
6. The driver drill according to claim 1 , wherein
the dial and the push switch are operable in different directions.
7. The driver drill according to claim 1 , wherein
the dial is rotatable by 360° or greater.
8. The driver drill according to claim 1 , further comprising:
a display,
wherein the controller is configured to cause the display to display a drive condition of the motor.
9. The driver drill according to claim 1 , wherein
the controller is configured to control behavior of the motor or time for a rotational speed of the motor to reach a predetermined value after the trigger lever is operated.
10. The driver drill according to claim 1 , further comprising:
an acceleration sensor,
wherein the controller stops the motor in response to the acceleration sensor detecting a value greater than an acceleration threshold.
