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.
Claims10
A power hand tool comprising a power section comprising a rotational output member to provide a rotational motion and a first and a second tool sections selectively and exchangeably connected to the power section to be driven thereby, each of the tool sections comprising releasable connecting means to connect to the power section, the first tool section further comprising first mechanical coupling means to couple to the rotational output member of the power section to receive the rotational motion therefrom and an end effector having an engaging member adapted to engage a jack to automatically actuate the jack, the second tool section further comprising second mechanical coupling means to couple to the rotational output member of the power section to receive the rotational motion therefrom and an output end adapted to engage a socket for loosening/tightening bolt/nut.
