The present invention relates to a kind of two-tube firearms of one shot mechanism, the purpose mechanism that especially drop bucket firearms are wherein invented is mounted on bed (1) and striking mechanism (2), to hammer (21), (4) connection that strikes spring in (3) is guided. There are the diode selector mechanism (9) to be attached at adjustable rocker arms (7), and thus position (8) bed (1) of the trigger is spring-loaded. The form (7) of the bottom end of the rocker arm, the eccentric discharging pawl (71) of formation are mounted on trigger (8) and rotationally and axially slide. The selector (9), is mounted on rear portion and slideably triggers (8), also has and rocker arm (7). Rocker arm (7) upper end, it is to enhance its shape, leans against the end of auxiliary lever (5) and connection below and guide part guidance (3) and be arranged essentially parallel to two rocker arms (7) and both arms trigger lever (6) is rotatably mounted to bed (1) central part each other. (2) and the rocker arm (7) with discharge claw (71) are hit in the hammering that the end (6) of the both arms trigger lever is adapted to engage with (21).
