Patent ID: 7779734

Claim:
A fastener drive-starter for a fastener with a head and a fastener shaft extending from a shaft-transverse head undersurface, comprising: a grip; a primary shaft extending along an axis and having a grip end attached to the grip and a hollow drive end opposite the grip end; a drive tip movably positioned within the hollow drive end of the primary shaft; a spring within the primary shaft and providing an axial force biasing the drive tip toward the drive end; a releasable fastener-locking mechanism extending between a mounted end non-movably attached to the primary shaft and a free end extending past the primary shaft to terminate with cross-portions extending substantially perpendicular to the axis; and a tightening member movably mounted to the primary shaft, the tightening member movable between a first position wherein the locking mechanism is open and a second position wherein the locking mechanism is closed toward the fastener shaft at the head such that the shaft-transverse head undersurface against the cross-portions which creates an axial force-resistance opposing the axial force, whereby the fastener is secured to the drive-starter by the axial force and opposing force-resistance sandwiching the fastener head between the tip and the cross-portions.
