2) when the ammunition is ignited and launched, the ammunition starts to generate displacement under the action of huge chamber pressure in the launching tube and rotates at high speed under the action of rifling in the launching tube, firstly, the overload of the recoil seat is sensed, and the limit spring pin relieves the limit of the rolling ball due to the overload of the recoil seat;

9. The control method as claimed in claim 7, wherein in the step 6), when the rotor rotates to rotate the rotor explosion propagation hole to the substrate explosion propagation hole position, the fixing pin assembly hole rotates to the fixing pin groove, and at this time, under the action of gravity, the bottom of the fixing pin leaks into the fixing pin groove from the fixing pin assembly hole, and the top of the fixing pin remains in the fixing pin assembly hole, so that the rotor is limited not to rotate any more.
