ABSTRACT:
The present invention refers to a dry firing prevention device, especially for use in a nail gun with a drawer type magazine, in which the main body of the nail gun is equipped with a safety apparatus and a dry firing prevention device near a trigger. The dry firing prevention device is disposed on the magazine. When a nail pusher pushes nails until where last few nails are left, the nail pusher will contact with one end of the dry firing prevention device and the other end of the dry firing prevention device blocks the safety apparatus, so that the safety apparatus retains in a safety status to prevent the nail gun from dry firing, so as to prolong the lifetime of the nail gun.
