Abstract:
An automatic screw catching device applicable to the bit of a power driven screwdriver for driving screws into a work piece, comprising:a bushing having a hole to insert the screwdriver bit; means for attaching the bushing to an appropriate location close to a front end of the screw driver bit; a sleeve mounted on the outer circumference of the bushing slideably mounted within a predetermined distance from the front end of the screwdriver bit in the direction of the axis of the bushing; means for catching and releasing the head of a screw including a circular portion frictionally engaged with the sleeve and a plurality of circumferencially spaced resilient fingers extending from the circular portion and forming an opening to engage and catch the head of the screw; a spring means normally biasing the sleeve forwardly with respect to the bushing; whereby when the head of a screw is caught by the resilient fingers and engaged with the bit, the bit can rotate to drive the screw, and the resilient fingers engage the work piece to move against the normal bias of the spring means during driving of the screw and the resilient fingers open to release the head of the screw when the screw is driven into the work piece.
