Patent ID: 8893594

Claim:
A fastener extraction device for attachment to a driver tool having a rotating chuck to drive a fastener into a surface, the rotatable chuck configured to rotate about a longitudinal axis of rotation and the fastener having a head with an elongated shank extending therefrom, the fastener extraction device comprising: a body defining a cavity to receive the rotating chuck therethrough; a collar moveably connected to said body; and a plurality of guide protrusions retained within a corresponding plurality of retention sleeves that are moveably carried within said collar to define a guide aperture through which the shank of the fastener is received, each of said guide protrusions normally biased towards the longitudinal axis of rotation by a plurality of corresponding biasing elements, such that the head of the fastener is retained behind said guide protrusions and is prevented from passing through the guide aperture when the head of the fastener is operatively engaged with the rotating chuck; wherein as the fastener is driven into the surface by the rotating chuck said guide protrusions retract into said corresponding retention sleeves away from the longitudinal axis of rotation of the rotatable chuck and said guide aperture expands to allow the head of the screw to pass freely therethrough.
