Claim Text:
1. A tool for extracting a pin having a free end from a substrate, the tool comprising: a first lever arm including a body part, the body part having a bore and a cavity communicating with the bore, the bore and the cavity being configured to receive at least a portion of the free end of the pin; a second lever arm pivotably connected to the first lever arm, the first lever arm and the second lever moveable between at least a first configuration, whereat the first lever arm and the second lever arm are separated by a first distance, and a second configuration, whereat the first lever arm and the second lever arm are separated by a second distance, the second distance being less than the first distance; a linkage arm having a first end and a second end, the second end pivotably connected to the second lever arm; a control arm having a free end and an opposite end, the free end pivotably connected to the first end of the linkage arm to pivotably connect the control arm to the second lever arm, and a jaw component extending from the opposite end of the control arm, the jaw component having a circular cross-section and being sized to be at least partially disposed and pivot within the cavity of the body part, the jaw component having a jaw bore and being pivotable between an unlocked position wherein the jaw bore and bore of the body part are aligned to receive a portion of a pin, when the first lever arm and the second lever arm are in the first configuration, and a locked position wherein the jaw component is pivoted to a position wherein the orientation of the jaw bore is changed so that the ends of the bore impart a localized bending force to a pin in the jaw component, when the first lever arm and the second lever arm are in the second configuration so that the jaw component engages the pin to substantially prevent the pin from sliding within the jaw bore when the jaw component is at the locked position; and a support pivotably attached to the second arm and slidably attached to the body part and slidable between a first position relative to the jaw component, when the first lever arm and the second lever arm are in the first configuration, and a second position more distal than the first position, when the first lever arm and the second lever arm are in the second configuration, the support including an end wall having an opening aligned with the bore of the body part.
