ABSTRACT:
A fastener removing tool including a driver having a head positioned within a housing which is movable along a longitudinal axis of the housing. Several levers are pivotally mounted within the housing, which each include a fastener-engaging first end extending from the housing and a driver head-engaging second end disposed within the housing and biased toward the driver head. The driver head includes a cone-shaped wedge which engages the second ends of the levers, a thread body that engages the housing, and a shaft which extends from the body for connection to a power tool. Movement of the driver head in the first direction pivots the levers to move the fastener-engaging first ends toward the longitudinal axis and thus onto the fastener, and movement of the driver head in the second direction pivots the levers to move the fastener-engaging first ends away from the longitudinal axis and fastener.
