<p><P>PROBLEM TO BE SOLVED: To provide a trigger system for an air gun using the trigger system similar to that of a rifle of a real gun. <P>SOLUTION: An assist collar 4 mounted at a rear part of a piston 1 in cocking the air gun, is advanced to a shear lock position by an assist collar push spring 6 when the shear 2 is opened and the piston 1 is advanced by a piston spring 5, to replace the piston 1, whereby the re-cocking is prevented in separating the trigger 3, and the piston can be smoothly retracted again without problems. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
