Nail gun structure

A nail gun structure comprising a gun body, a clamp set and a pneumatic driving set;

• the clamp set assembled with the gun body, the clamp set having a driven base and a clamp base defined thereon, the clamp base pivoting relative to the driven base so as to move toward or away from the driven base, at least two boards stacked and aligned to form a stacked board, the stacked board positioned on the clamp base and clamped between the clamp base and the driven base when the clamp base pivots relative to the driven base, the stacked board corresponding to an outlet of the gun head for shooting the nail;
• and
• the pneumatic driving set disposed between the gun body and the clamp set, the pneumatic driving set communicating with an air pressure source, the pneumatic driving set moved along with a trigger of the gun body;
• wherein when a user pulls the trigger, the pneumatic driving set is moved simultaneously so as to push the clamp base pivoting relative to the driven base, so that the stacked board is positioned and clamped between the clamp base and the driven base;
• and then, the nail is shot from the gun head and nailed on the stacked board;
• lastly, the clamp base pivotally moves away from the driven base when the trigger is released by the user.
