| 摘要 |
The invention relates to a shooting system comprising a housing (1) and parts that can be moved relative thereto, i.e. a tube (2), a tube closure (3), and a silencer (5), as well as a non-self-locking threaded spindle which has a left-handed threaded section (4a) in one of the halves thereof while having a right-handed threaded section (4b) in the other half. The silencer and the tube closure are mechanically coupled to one respective threaded spindle section by means of one respective nut (N, N1) such that a translational movement of the silencer (5) is converted into a rotational movement of the spindle and the movement of the spindle is converted into a translational movement of the tube closure (3), in such a way that both parts perform translational movements in opposite directions because of the right-handedness and left-handedness of the spindle. The tube (2) is disposed to also be movable relative to the housing (1) and can be coupled to the tube closure (3) in such a way that the tube is entrained by the tube closure at least during a translational movement of the tube closure, during which the tube closure moves away from the silencer from a shot-triggering position. |
