Abstract
A nail driver includes a braking unit and a resilient element. The braking unit has a protrusion and is pushed by the resilient element. The braking unit is abutted to a nail pusher of the nail driver to push nails together with the nail pusher in a nail cartridge of the nail driver. When there is no more nail left, the braking unit is pushed to block in the moving path of a securing slide rod of the nail driver so that the nail drive cannot be actuated until the nails are reloaded.
