ABSTRACT:
A manually powered fastening tool which stores and instantly releases the energy of a spring such that it may force a fastener into an object by an impact blow in which the operating handle is hinged near the end of the tool body opposite the end from which the staples exit. The main spring is a single piece flat torsion spring which decreases in cross-section away from its fulcrum point to enable the entire spring to provide energy storage. The operating handle is linked to the spring through a low friction rolling element which provides varying leverage to allow a constant operating force through the operating handle motion. The staple guide track includes position and latch feature within a one piece assembly.
