Abstract
A fastening tool includes a bit holding portion configured to detachably hold a driver bit and rotatable in a circumferential direction and movable in an axial direction, a first motor configured to rotate the bit holding portion, a position detector configured to detect a position of the bit holding portion along the axial direction, and a controller configured to drive the first motor to rotate the bit holding portion. The controller is configured to determine, based on the position of the bit holding portion, whether the bit holding portion moves to a forward movement end position and to stop the rotation of the first motor in a case where the bit holding portion does not reach the forward movement end position and a stop condition of the first motor is satisfied.
Claims13
A fastening tool comprising:
- a bit holding portion configured to detachably hold a driver bit and rotatable in a circumferential direction of the driver bit held in the bit holding portion and movable in an axial direction of the driver bit held in the bit holding portion;
- a first motor configured to rotate the bit holding portion;
- a position detector configured to detect a position of the bit holding portion along the axial direction of the driver bit;
- and
- a controller configured to drive the first motor to rotate the bit holding portion, wherein
- the controller is configured to determine, based on the position of the bit holding portion detected by the position detector, whether the bit holding portion moves to a forward movement end position and to stop the rotation of the first motor in a case where the bit holding portion does not reach the forward movement end position and a stop condition of the first motor is satisfied.
A fastening tool comprising:
- a bit holding portion configured to detachably hold a driver bit and rotatable in a circumferential direction of the driver bit held in the bit holding portion movable in an axial direction of the driver bit held in the bit holding portion;
- a first motor configured to rotate the bit holding portion;
- a contact member configured to come into contact with a fastening target to which a screw engaged with the driver bit is fastened;
- a contact switch portion capable of moving between an ON state and an OFF state by movement of the contact member in the axial direction;
- a position detector configured to detect a position of the bit holding portion along the axial direction;
- and
- a controller configured to drive the first motor to rotate the bit holding portion, wherein
- the controller is configured to
- control a timing at which driving of the first motor is stopped based on whether the contact switch is in the ON state or the OFF state,
- determine whether the contact switch portion is in the ON state or the OFF state when the controller determines that the bit holding portion moves to a forward movement end position based on the position of the bit holding portion detected by the position detector, and
- continue the rotation of the first motor until a stop condition is satisfied in a case where the contact switch portion is in the OFF state.
