  • Power driven wrench
    Patent number: 7089827
    Abstract: A power driven wrench comprises a head having an opening which carries a toothed or threaded rotary member substantially completely within the head. A shaft is present having a toothed or threaded inner end which engages the toothed rotary member, extending through an aperture in the head, to cause the rotary member to rotate as the shaft rotates. The shaft also has an outer end that can engage a power source to rotate the shaft. The rotary member defines an aperture capable of firmly holding within the head a driver member having a polygonal opening for receiving heads of objects to be rotated by the wrench. The driver member is replaceable by another driver member having a different polygonal opening without any disassembly of the head. A short wrench embodiment is disclosed.
