特徴とするクラツチ式電動ドライバ。 The motor drive shaft of the driver and the driver shaft are connected intermittently through a speed reduction mechanism and a clutch, and the driver shaft is reciprocated in the axial direction by the tool pressing force and the release of the pressing force, thereby controlling the rotation and speed of the motor.
In a clutch-type electric screwdriver that performs stopping, when the screw tightening bit at the tip of the driver reaches a predetermined tightening torque, the movable clutch on the driver shaft side and the fixed clutch on the motor drive shaft side are completely disengaged. A clutch-type electric screwdriver characterized in that the clutch-type electric screwdriver is further provided with means for re-engaging both the clutches when the tool pressing force is released upon completion of screw tightening.
