Abstract
The present invention relates to a safety device for preventing a nailer from dry firing, wherein an elongated hole is formed on the magazine, the safety link is provided with a folded projection in response to the elongated hole, a safety nut is pivotally disposed in the elongated hole. The magazine is provided with an elastic element for keeping the safety nut flush with the edge of the elongated hole. After the last nail is shot (when no nails are loaded), the safety nut will be pushed out of the elongated hole by the drive plate so as to prevent the nailer from being fired. Thus, the user's strength and energy are saved, meanwhile, the service life of the nailer is prolonged.
