The mechanism is used in the war industry and is designed to be built in automatic and semiautomatic fire arms such as pistols, submachine guns and automatic weapons. It has simplified design which improves its safety when the charged weapon is carried without a safety pin thus eliminating any risk of firing by accident. It consists of striking, trigger and reswitching mechanism joined together by a rear block (30). The reswitching mechanism is in the form of a switch (29) fitted behind a closed assembly (34) with an ejector. In the central part of assembly (34) an internal stepping groove (7) is machined in which a firing pin (1) is fitted. A profile cog (2) for meshing with the trigger mechanism with a trigger (15) supplied with a reversive spring (18) and pivotly connected to the frame-handle (35) is machined projecting an outside assembly (34) to the striking pin (1). A single-arm lever is connected to trigger (15) fabricated in the form of a traction (10) pressed to assembly (34) by spring (19). Traction (10) has upper cam-type surface (11) and cog (12) for contacting the striking pin mechanism. Between the two extensions two axially mobile rings (3 & 5) are fitted separated by the spiral firing spring (4) wound around the firing pin (1). 5 claims, 14 figures
