Abstract
The self-contained force magnifying tool disclosed herein includes a tool portion, a striker, at least a portion of which is disposed within the tool portion, and a spring, a least a portion of which is disposed within the tool portion. The spring attaches to both the tool portion and the striker. When the striker is pulled by a user, the spring stores mechanical energy. When the user releases the striker, the striker impacts on the tool portion transferring the mechanical energy stored in the spring into a driving force. The force is magnified by a tool disposed on the tool portion of the self-contained force magnifying hand tool and applied to a workpiece.
