Driver jaws for an automatic screw feeding machine

摘要

Driver jaws for a driver head of an automatic screw feeding machine are disclosed. A pair of cantilever springs are oppositely disposed on a mandrel or housing. The springs are arranged such that the tips thereof form an opening therethrough which comprises the jaws for holding a fastener during the insertion process. The cantilever springs allow the jaws to open to permit the head of the fastener to pass therethrough after the fastener is fully inserted and to be released from the driver jaws. The cantilever springs permit an exceptionally small clearance spaced around the head of the installed fastener. The tips of the jaws spaced the movable portions of the apparatus away from the work surface so that marring or scratching of the work surface is avoided.
