Abstract:
1. A shooting mode switch control mechanism installed in a gun body of a nail gun and pushable by a safety bar to activate an air-valve switch for firing nails, comprising: a trigger pivotally mounted in said gun body; a stop member pivotally mounted in said trigger, said stop member having a first end portion and a second end portion disposed at two opposite sides relative to the pivoted area between said stop member and said trigger; a spring member mounted in said gun body at the side of the second end portion of said stop member, said spring member being stopped against the second end portion of said stop member to impart a spring force to said trigger through said stop member for biasing said trigger in direction away from said air-valve switch; and a switch pivotally mounted in said trigger at the side of the first end portion of said stop member and switchable between a single-shooting position and a continuous-shooting position; wherein when said switch is in said single-shooting position and said trigger is pressed, the second end portion of said stop member is kept beyond the moving path of said safety bar; when said switch is in said single-shooting position and said trigger is released, the second end portion of said stop member is forced by said spring member into the moving path of said safety bar and pushable by said safety bar for enabling said stop member to activate said air-valve switch once each time said trigger is pressed; when said switch is in said continuous-shooting position, the first end portion of said stop member is stopped against said switch for enabling the second end portion of said stop member to be continuously pushed by said safety bar to activate said air-valve switch continuously.
