Abstract

Abstract According to one embodiment, a power driven socket wrench is disclosed to rotate nuts and bolts in confined spaces including a head formed of a rotatable socket for engaging nuts and bolts, a bearing for the rotatable socket and a housing around the socket and bearing. The socket has a plurality of gear teeth thereon extending around its axis. An important feature of the invention is the provision of a drive adapter between the head and a power drive for driving the socket. The adapter is detachable from the head and the power drive for replacement by an adapter of a different length to enable reaching a nut or bolt at a more remote distance. The adapter has an outer elongate housing containing an elongate drive shaft mounted axially therein on suitable bearings. The adapter housing and shaft are positioned for rotation of the shaft on an axis extending perpendicular to the rotational axis of the socket on the head. A rotatable input gear is mounted on the inner end of the shaft and meshes with the gear teeth around the socket for driving same. The adapter has a detachable locking means such as a snap lock at its inner end for detachably locking the adapter onto the housing of the head. The outer end of the adapter drive shaft has a detachable locking member for detachably engaging the driver member of a power drive or motor.
