ABSTRACT:
A multi-purpose hand tool having novel structure that allows it to partially function in the manner of a revolver. It has a multi-chamber revolver-like cylinder which revolves and holds various sizes of screw drivers, Phillips head drivers, Allen wrenches, sockets, screw starters, etc. The tool has a primary shaft whose rear end is connected to the drive shaft of a D.C. electric motor mounted in the rear body assembly. The drive shaft passes through an aligned bore hole in the front body assembly that is mounted immediately behind the revolver-like cylinder. The rear body assembly is mounted in a track formed along the top edge of the handle assembly so that the rear body assembly may be reciprocally moved rearward to disengage the primary shaft from one driver tool to the next driver tool that the user desires to place on the end of the primary shaft. The front body assembly has been designed so it may be used in conjunction with the revolver-like cylinder in a manual operation by removing the front body assembly and attaching a ratchet handle assembly to its rear end. Various auxiliary assemblies can be detachably mounted to the hand tool.
