Patent attributes
A blocking device for a nail gun includes a push member disposed on a nail pusher in a nail cartridge of the nail gun for moving toward a nail groove base with the nail pusher, a brake member movably installed on the nail pusher for moving toward the nail groove base with the nail pusher, and a rotational fastener pivotably installed on the nail groove base on a moving path of the push member and the brake member. The fastener can be touched to rotate by the push member when there are a small number of remaining nails in the nail cartridge so as to prevent the brake member moving to a position where it blocks an upward movement of the safety bar, and can be released by the push member and rotate back to an original position when there is no remaining nail in the nail cartridge so as to release the brake member to move to a position where it blocks an upward movement of the safety bar and thereby a nail shooting action of the nail gun. The accuracy of the nail shooting blocking is improved.
