摘要

The pistol has a handle whose face is bolted axially with a threaded cap, and a back stop (5) with a dual leg spring. The cap has a hole to admit a shaft (7), on which a compression spring, with a metal bush is provided. The bush is pushed forward with operation of a lever (10) by a movable transport gear (4) and pushed backward by the spring and by the release of lever. The shaft is reclined by 1-1.5 millimeter before it is locked. The bush is pushed backward so that a pressure is exerted on the gear and the lever is pushed again into its former position.
