Abstract
A nail gun includes a rotatable shaft which can lock a switch of a trigger of the nail gun in a nail-empty condition. The rotatable shaft has a locking portion and a driven portion extending partly into a nail magazine, such that when a nail pushing member disposed in the nail magazine reaches a predetermined position, the nail pushing member pushes the driven portion to make the rotatable shaft rotate about an axis perpendicular to a marching direction of the nails loaded in the nail magazine. As a result, the locking portion of the rotatable shaft in an initial position and spaced away from the switch will move to a locking position to be engaged with the switch. Therefore, the nail gun can shoot nails continuously until there is totally no nail in the nail gun and the nail gun is locked.
