Abstract:	Traditional firearms use the principle of mechanical impact to achieve shooting function. In order to realize intelligence and informatization of firearms and prevent accidental triggering, mechanical transformation of the mechanical structure of firearms is a necessary step, of which circuit power supply is the primary problem to be solved. By using the principle of induction firing, this paper designs an experiment to replace the firing pin part with a miniature linear motor at the socket, and use coil assembly to cut a magnetic induction wire after the trigger is pulled to generate voltage to realize circuit power supply of a pistol.Considering the inner space of the pistol socket, the induced voltage of the coil and the charging time of the tantalum capacitor, the optimal distance is obtained by COMSOL Multiphysics electromagnetic simulation when the piston assembly has a motion stroke of 14 mm.
