发明名称 Fastener holding device
摘要 A fastener holding device is designed for use with power or hand tools. The device securely engages a fastener, such as a screw, and automatically disengages the fastener when the device is pushed against a work surface. The device includes a driving bit assembly which has a socket on one end for holding a driving bit and has a polygonally shaped portion on the other end for mounting in a power drill. The device further includes a retaining member adapted to be placed on the driving bit assembly and a sleeve member adapted to be placed on the retaining member. The position of the sleeve member in relation to the retaining member allows the fastener to be either engaged or disengaged with respect to the driving bit.
