ABSTRACT:
The present disclosure concerns a cordless electric screwdriver which incorporates its own set of male electric power tangs for direct connection to a standard, household power socket. The tangs are extended or retracted from the ergonomically designed housing by virtue of communal mounting upon a carriage which is movably supported by the housing. Further, by orienting the projection of the extended tangs to be centered on a line passing through the center of gravity for the screwdriver, the screwdriver is facilitated to endure extended periods of support solely by the tangs being "plugged-in" to the household power socket. The ergonomic design features of the housing include a combination of surface texturing as well as relative cross-section sizing and shaping.
