Claim:
An actuating mechanism installed in a mount inside a gun body of an air gun and covered by a slide of said air gun, the actuating mechanism comprising: a hammer pivoted to a rear side of said mount; a front pivot transversely mounted into said mount near a front side of said mount; a rear pivot transversely mounted into said mount between said front pivot and said hammer, and spaced behind said front pivot at a distance; a hook member pivotally mounted on said rear pivot inside said mount, said hook member having a rearwardly directed hooked portion engaging with said hammer; a movable block mounted on said front pivot and said rear pivot, said movable block having a front longitudinally elongated through hole for the passing of said first pivot and a rear longitudinally elongated through hole for the passing of said rear pivot with a first stop edge and a second stop edge selectively forced into engagement with said front pivot and a rear butt contacting said hammer; and a spring member stopped between said movable block and said rear pivot; wherein when the user moves said slide to a rear side of said gun body, said rear butt of said movable block is forced downwards by said slide, said movable block is moved to compress said spring member and to force said first stop edge into engagement with said front pivot, and said hook member is forced to turn said hammer backwardly downwards to a hammering position; when the user triggered said air gun, said hammer is disengaged from said hook member to strike said rear butt of said movable block, and said movable block is returned by said spring member to shift said first stop edge away from said front pivot and said second stop edge into engagement with said front pivot.
