Force applying booster of gun firing pin and control circuit of force applying booster

The invention discloses a force applying booster of a gun firing pin and a control circuit of the force applying booster. The booster comprises the firing pin and a boosting mechanism. The firing pinhas variable magnetism, and the boosting mechanism is arranged in a firing pin channel arranged in a gun. The boosting mechanism comprises a magnetic shielding cavity, a permanent magnet and an electromagnetic coil. The magnetic shielding cavity is formed by a magnetic shielding material and provided with an open end. The permanent magnet is arranged at the bottom end of the magnetic shielding cavity, and the electromagnetic coil is arranged at the front end of the permanent magnet. The firing pin is arranged in a hollow part of the electromagnetic coil. The variable magnetism of the firing pin is achieved by changing the direction of current introduced into the electromagnetic coil. Voltage boosting is carried out through a charge pump, a transformer voltage boosting mode is avoided, andthe characteristics of bei
