SCREW-TIGHTENING POWER TOOL |
| 摘要 |
A screw-tightening power tool includes a motor housing. A brushless motor has a stator that is fixed to the motor housing and a rotor that is rotatable relative to the stator. A tip-tool retaining part is configured to hold a bit and a clutch is disposed between the rotor and the tip-tool retaining part. A grip housing extends from the motor housing. A switch assembly is provided in the grip housing and a trigger is held by the switch assembly. A sensor-circuit board is fixed to the stator. The sensor-circuit board and the switch assembly are connected by a first cord, and the stator and the switch assembly are connected by a second cord. |
