ABSTRACT:
The present invention provides an adjustable and automatically disengaging overload clutch for driving a tool, comprising a first clutch half frictionally engaged with a second clutch half and a coupler bracket for transmitting torque form the second clutch half to the tool. The clutch further comprises a spring connecting the second clutch half to the coupler bracket to transmit torque from the second clutch half to the coupler bracket. The spring is designed so that if a predetermined torque is exceeded, the second clutch half is released from the coupler bracket, thus preventing the transmission of any further torque. Levers associated with the coupler bracket and the second clutch half are also provided for disengaging the second clutch half from the first clutch half.
