This invention relates to hand-held light weapon firing devices. To resolve the present problem of the excessive length of the work travel of the firing device trigger, with large frictional surface resistance between the blocking iron and the track, thus directly affecting the precision of firing. It is characterized in that it has a rotating blocking iron, which is fixed to the firing mount by the rotating blocking iron shaft; the rotating blocking iron shaft, the rotating blocking iron shaft hole and the hole in the frame for the rotating blocking iron shaft together forming a rotating assembly. This converts the translational friction of the original blocking iron on the track into rotational friction, the linear translational motion of the original blocking iron becoming the eccentric rotational motion of the rotating blocking iron, reducing the length of travel of the trigger from 6 -7 mm to 2 -2.5 mm, reducing frictional resistance and making it easy to operate during firing, thus creating the conditions for improvement in and guarantee of precision in firing.
