ABSTRACT:
An exchange power hand tool includes a power section having a motor encased in a housing and two tool sections, respectively serving as a wrench and a jack actuator, alternately and exchangeably engageable with the power section to be driven thereby so as to provide one power hand tool with two functions. The power section has an output pinion mounted on the motor spindle to be engageable by a driving gear chain of the tool sections for transmission of torque from the power section to the tool section for selectively performing wrenching operation or jack actuation.
