The break mechanism includes an elastic member disposed between the break member and the side cover, the elastic member is configured to drive the break member to swing towards the hitting slot and the nail guiding track; and a break member having a detection portion and a block member. The detection portion is capable of detecting push action of a single nail in the hitting slot and the nail in the nail guiding track adjacent to the nail in the hitting slot. When the break member is pushed by the nail in the hitting slot or the adjacent nail in the nail guiding track, the block member releases the security slide rod. When the break member is released by a last nail in the hitting slot, the block member brakes the security slide rod. The nail gun used the break mechanism has a high reliability.
