<p>A pneumatic tool lock integral to the structure of a pneumatic tool and adapted to replace the existing male nipple component of the pneumatic tool is provided. The pneumatic tool lock includes an outer housing adapted to provide access to inner components of the pneumatic tool lock, the outer housing having a first end for securel y mating with the pneumatic tool and a second end for coupling with a fluid source. An inner passageway within the outer housing provides a means for fluid to flow through from the fluid source to the pneumatic tool. A key operated lock mounted on the outer housing is displaceable between a first open position and a second closed position. A needle valve attached to the key operated lock disengageably mates with a channel extending between the inner passagew ay and the outer housing so as to block and un-block fluid flow into the inner passageway. When the key operated lock is displaced in the first open position, the needle valve disengages from the channel so as to allow fluid to flow into the inner passageway and when the key operated lock is displaced in the second closed position, the needle valve mates with the channel so as to inhibit fluid from flowing into the inner passageway.</p> |
