This is a kind of deflagration nail gun with sliding components (1,3,4,8,17) and percussion switch devices (20). Described percussion switch devices (20) include: station-keeping U-shaped steel wire (17) with a jumper; pivoted percussion switch base (11) with a notch (116) at the back of its upper edge; ignition switch (14) fixed on percussion switch base (11), with a prominent button upward; touch switch chip (12), of which, one of its end can be pivoted installed in the ignition switch (14), another end can extend from percussion switch base (11) to the top touch chip on the top of notch (116), and the central of touch switch chip (12) is joined to touch button. When the sliding component is located in the front-side position and the upper edge of percussion switch base is located at the bottom of jumper of U-shaped steel wire (17), the jumper (172) can prevent switch base (11) being pivoted along the direction of triggering. When the sliding component (1,3,4,8,17) is located in the back-side position, the notch (116) of percussion switch base (11) is located under the jumper (172) of U-shaped steel wire (17), which allows switch base (11) to pivot along the direction of triggering. A deflagration nail gun with higher security can avoid the accidental shooting of nails causing human harm.
