ABSTRACT:
A nailer includes a gun body, a magazine, a feed plate, a washer barrel, a catch plate, and a locking ring. Thus, the washer is closely positioned between the catch flange of the feed plate and the locking ring, thereby facilitating a user combining the washer with the nail. In addition, the locking ring is tensioned only when the washer passes through the locking ring, so that the locking ring is not maintained at the tightened state constantly, thereby preventing the locking ring from producing fatigue, and thereby enhancing the lifetime of the locking ring. Further, the locking ring is used to stop washers made of plastic or metallic material, thereby enhancing the versatility of the nailer.
