ABSTRACT:
A nail driver includes a cell formed inside a nail cartridge. A braking unit with one end formed as a retaining portion and the other end formed as a contact portion is pivotally installed in the cell. A resilient member is installed in the cell for pressing on the contact portion to swing the retaining portion to a releasing position so that a securing slide rod can freely slide to have the nail drive being actuated when there is any nail in the nail cartridge. When there is no more nail, a nail pusher pushed by a spring makes a protrusion of the nail pusher pressing on the contact portion against the resilient member to swing the retaining portion to a restraining position to block in the moving path of an extending portion of the securing slide so that the nail drive cannot be actuated until the nails are reloaded.
