ABSTRACT:
This blow gun assembly (10) includes a blow gun (12) which includes a quick-change coupling adaptor (20) to facilitate the connection of an assortment of nozzles (22). The coupling adaptor includes a body (34) threadedly connected to the outlet end (18) of the blow gun and having a ball lock latch mechanism (42, 44), a spring-biased plunger (50) and a spring-biased external sleeve (60). The nozzle icludes a circumferential groove (30) receiving the balls when the nozzle is pushed into the adaptor body against the bias of the plunger to latch the nozzle in place. The plunger (50) includes guide tongue elements (58) received by cooperating grooves (48) in the body. The plunger tongues are spaced rearwardly of the forward end of the plunger so that the plunger tongues engage the balls to limit forward movement and the plunger overlaps the balls in the forward position, when the nozzle is ejected by pulling back on the sleeve.
