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.

1. A blocking device for a nail gun, the blocking device being installed on the nail gun, the nail gun having a nail groove base, a safety bar, and a nail cartridge, the blocking device comprising: a push member, disposed on a nail pusher in the nail cartridge and configured for moving toward the nail groove base along with the nail pusher pushing multiple nails;a brake member, movably installed on the nail pusher by a first spring force, and configured for moving toward the nail groove base with the nail pusher pushing the multiple nails; anda rotational fastener, pivotably installed on the nail groove base by a second spring force on moving paths of the push member and the brake member, having a touch part configured to be touched to rotate by the push member and a fastening part configured to have physical contact with the brake member to stop the brake 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 the brake member blocks an upward movement of the safety bar, and configured to be released by the push member and to 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 the position where the brake member is engaged to an end groove formed on the nail groove base and have physical contact with the safety bar to block the upward movement of the safety bar, the small number of remaining nails being less than ten nails,wherein a guiding groove is disposed on an end of the nail pusher facing the nail groove base, the guiding groove being configured for slidably mounting the brake member thereon, andwherein a first elastic member is disposed between the guiding groove and the brake member, the first elastic member being configured for providing the first spring force. 2. The blocking device for a nail gun as described in claim 1, wherein a containing groove is disposed on an end of the nail groove base connecting to the nail cartridge, the containing groove being configured for containing the push member when the push member moves into the containing groove while there is no remaining nail in the nail cartridge. 3. The blocking device for a nail gun as described in claim 1, wherein the push member comprises an ear board, the ear board being configured for touching the fastener when there are the small number of remaining nails in the nail cartridge. 4. The blocking device for a nail gun as described in claim 1, wherein a blocking part is formed on an end of the brake member, the blocking part being configured for moving to the position to block the safety bar from moving upwards, and a ladder-shaped surface is formed on the brake member, the ladder-shaped surface being configured to be stopped by the fastener. 5. The blocking device for a nail gun as described in claim 1, wherein a pivot part is disposed on an end of the nail groove base connecting to the nail cartridge, and the fastener is pivotably disposed on the pivot part. 6. The blocking device for a nail gun as described in claim 1, wherein a second elastic member is disposed between the fastener and a pivot part which is disposed on an end of the nail groove base and configured for providing the second spring force.
