  • Publication number: 20030121948
    Abstract: A magazine includes two passages defined therein and each passage has a spring, a pushing member and an end piece received therein. The spring biases the pushing member and each end piece has a resilient member received therein and a pin movably extends through two slots defined in two opposite walls of the end piece. The pin is fixed to the magazine and the resilient member is biased between an inside of the end piece and the pin. A pushing plate is movably connected to the two pushing members so as to push nails in the magazine toward the nose connected to the magazine. The end pieces protrude into the nose when the pushing members push the end pieces while no nail is located in the nose. The protrusion of the end pieces in the nose prevents the safety device from being pushed.
