<p>A manually powered fastening tool which stores and instantly releases the energy of a spring (40) such that it may force a staple (70) or other fastener into an object by an impact blow in which the operating handle (22) is hinged near the end of the tool body opposite the end from which the staples (70) exit. A staple ejecting plunger (21) is unstably linked to the spring (40) such that when a lever (28) moved by the operating handle (22) to energize the spring (40) slips past ledges (11, 13) thereby removing a light holding force, the lever (28) disengages from the spring (40), which releases the plunger (21). The tool housing (10) comprisses a cantilevered rear profile.</p> |
