[0027] Working principle of the utility model: when in use, the user first connects the gas tank through the threaded structure 3 on the connecting pipe 2. At this time, the air pressure in the grip 1 pushes the firing button 5 outward and is transmitted to the air pressure box 2 7 through the connecting pipe 6, so that the block 8 blocks the channel between the grip 1 and the firing chamber 9 to keep the internal air pressure balanced. Then, the limit plate 26 is slid in the direction of the fixed block 24 to compress the spring 25, and the baffle 23 is pulled downward. Then, the top plate 20 is pressed to compress the spring 19, and the row of nails is placed in the middle of the connecting block 21 and the top plate 20, so that the first row of nails is located in the firing hole 22. Then, the baffle 23 is slid upward until it fits the bottom of the connecting block 21. Under the action of the spring 25, the limit plate 26 is reset to jam the baffle 23 to prevent it from falling. When firing the nails, the firing button 5 is pressed inward. At this time, the firing One end of the firing button 5 fits into the channel between the grip 1 and the air pressure box 4, and the gas in the air pressure box 7 is discharged into the air pressure box 4 through the connecting pipe 6 and discharged through the gap between the air pressure box 4 and the firing button 5. At this time, there is a lack of pressure in the air pressure box 7, and the stopper 8 slides into the air pressure box 7, and the high-pressure gas flows into the firing chamber 9, and then pushes the sliding block 10 to make the firing pin 11 slide into the firing hole 22, thereby pushing the first nail to be fired. After the firing, the firing button 5 is released, and one end of the firing button 5 completely seals the air pressure box 4, and the high-pressure gas flows from the grip 1 into the air pressure box 4, and returns to the air pressure box 7 through the connecting pipe 6, pushing the stopper 8 to reset. At this time, the gas in the firing chamber 9 is directly discharged through the exhaust hole 14 on the back cover 13, so that the sliding block 10 drives the firing pin 11 to reset, and it is used reciprocatingly in sequence.
