摘要： A fire control system for a semiautomatic, double-action only pistol includes a sear carried at the free end of a cantilevered spring. As in other pistols, the sear engages a striker to load it against a striker spring until it is released to fire a chambered round. In the present invention, the cantilevered spring urges the sear forward and upward, against the rearward movement of the sear as a result of the pulling of a trigger operating through a trigger arm, and restores the sear after release of the striker. The cantilevered spring is preferably a spring with a torsion spring on each end. One torsion spring operates against the frame to cantilever the spring body; the other torsion spring, supporting the sear, operates on it to urge it forward. The sear and the striker lay in the same plane. Therefore, the sear has a second cam surface that engages the striker leg when the trigger is released, urging the sear downward as the striker passes over it to set up the sear for loading the striker the next time the trigger is pulled.

摘要翻译： 用于半自动双作用手枪的消防控制系统包括在悬臂弹簧的自由端承载的烙铁。 与其他手枪一样，狙击手接合前锋将其装载在撞击弹簧上，直到它被释放以发射一个圆形的圆形。 在本发明中，悬臂弹簧由于通过扳机臂的拉动操作而抵抗着火腿的向后运动而向前和向上推动冲击器，并且在释放冲击器之后恢复冲击。 悬臂弹簧优选地是在每个端部上具有扭转弹簧的弹簧。 一个扭转弹簧抵靠框架抵靠弹簧体; 另一个扭转弹簧，支撑着sear子，在其上操作以推动它向前。 狙击手和前锋躺在同一架飞机上。 因此，当触发器被释放时，冲击器具有接合冲击器支脚的第二凸轮表面，当冲头经过它时向下推动冲击器，以便在下一次拉动扳机时设置冲头以装载冲头。
