1, the high-tenacity spring fitting is in the permanent magnets hollow cup, the high-tenacity spring is equipped with a spring top board at an end of permanent magnets hollow rim of a cup, when the high-tenacity spring is compressed, the cross empennage of flat bullet is being pasted on top, spring top board center, two spring kayser swivel plates are equipped with in the spring top board both sides wider at flat, spring kayser swivel plate one side pressure is on the outer ledge of spring top board, the other end is pressed in the high-tenacity spring on the little magnetic patch of spring kayser of the same side, these two little magnetic patch of spring kayser move by outer magnetic force, can rotate the compressed state of release high-tenacity spring by control spring kayser swivel plate, thereby make compressed high-tenacity spring rapid elongation, and will be close to flat bullet on the spring top board with larger elastic force and faster the speed bullet from the spring top board, and then the flat bullet can be obtained away from permanent magnets and the higher initial velocity consistent with high-tenacity spring direction of ejection, and, after accelerating to obtain higher speed through repeatedly circling round in magnetic artillery magnetic holder bullet is circling round acceleration orbit, the compressed state of release high-tenacity spring, make compressed high-tenacity spring rapid elongation, and while launching the flat bullet, can make too the flat bullet at the original larger initial velocity of middle acquisition that advances at utmost speed.

2, the radian of the upside cambered surface of flat bullet wants large than the radian of downside cambered surface, purpose is to make the flat bullet in flight course, the air stream that can form flat bullet upside cambered surface is greater than through speed the air velocity that the downside cambered surface is flowed through, thereby make the flat bullet can produce a less lift in flight course, be subject to the impact of gravity to reduce its flight curve.

3, the gross weight of flat bullet is less than the gross weight of magnetic bullet holder, the gross weight that is the flat bullet is less than the weight sum of permanent magnets and the little magnetic patch of spring kayser and high-tenacity spring and magnetic holder shell, spring kayser swivel plate, spring top board, purpose is that the flat bullet is being launched by the high-tenacity spring while separating with the spring top board, can to greatest extent the flat bullet be launched away, can make the flat bullet obtain to greatest extent initial velocity because of the effect of launching of high-tenacity spring.

4, the pole orientation of permanent magnets is consistent with the prolonging direction of high-tenacity spring, and the pole orientation of two little magnetic patch of spring kayser is consistent, and vertical with the pole orientation of permanent magnets, perpendicular to the prolonging direction of high-tenacity spring.

5, for the magnetic field of the little magnetic patch of high-strength influence of magnetic field spring kayser that prevents permanent magnets, can between permanent magnets and the little magnetic patch of spring kayser, add a thicker magnetic conductive board.

6, the flat bullet can be made solidly, also can in bullet, dose explosive ammunition lethal to increase it.

The present invention compared with prior art has the following advantages:

1, do not find that there is the patent documentation report of similar magnetic artillery magnetic holder bullet.

2, bullet utilize the high-tenacity spring in the bullet holder when magnetic holder bullet high-speed cruising, bullet to be launched, so that can obtain larger initial velocity.

3, magnetic artillery magnetic holder bullet of the present invention can be made permanent magnets larger high strength permanent magnet body, the efficiency of accelerating to improve convolution.

4, magnetic artillery magnetic holder bullet of the present invention can be reused, and can reduce the manufacturing cost of bullet.
