Abstract
An electric screwdriver assembly includes a body portion, a screwdriver and a vacuum coupling assembly. The body portion defines a screw conduit therethrough which has a distal end and at least one opening spaced apart from the distal end. The screwdriver is disposed within the body portion and includes a free end facing the distal end of the screw conduit that defines a screwdriver bit. The screwdriver bit is moveable through the screw conduit between a position proximal from the opening and a position distal from the opening. The vacuum coupling assembly is configured to couple to a vacuum generator to the body portion in order to generate a partial vacuum within the screw conduit through the opening to substantially align the screw with the at least one opening.
