Abstract
An electric quick action wrench with settable torque, which is operated in an electric mode or a manual mode, includes: a main body, a controller, a motor, a driving device, and a clutch device. The driving device is driven by the motor and combined with a fastener. The controller sets a threshold torque value. In the electric mode, when the fastener confronts a resistance larger than a clutch torque of the clutch device, the user is notified to switch to the manual mode through the notification of the clutch device. In the manual mode, when a manually output torque reaches the threshold torque value, the user is notified that the screwing operation has been finished by the notification of the clutch device. Thus, the safety of usage is achieved.
