1. A rocket structure, comprising: a warhead;a rocket body connected to the warhead, the rocket body being peripherally provided with a plurality of fins, each said fin being connected to the rocket body via a torsion spring;a rocket motor connected to the rocket body, the rocket motor comprising: an outer casing, a bottom of which has a first coupling hole and at least one fixing hole;at least one fixing member extending into the outer casing through the fixing hole;a first supporting member having two opposite hollow ends, extending into the first coupling hole, and coupled to the outer casing;a first bullet placed on the first supporting member from inside the outer casing and supported by the first supporting member;a connecting member having two opposite hollow ends, which are respectively provided with a first connecting portion and a second connecting portion, the connecting member being connected to the first bullet via the first connecting portion;an inner casing, a bottom of which has a second coupling hole, the inner casing being placed in the outer casing and fixed on the fixing member;a second supporting member having two opposite hollow ends, wherein one said end of the second supporting member extends into the second coupling hole and is coupled to the inner casing, and the other end of the second supporting member is connected to the second connecting portion of the connecting member, the second supporting member further having a shielding portion;a metal plate having at least one through hole, the metal plate being placed in the second supporting member such that the through hole is shielded by the shielding portion;an elastic member placed in the second supporting member and located on the metal plate;a second bullet placed on the second supporting member from inside the inner casing and abutting against the elastic member; anda plastic cover lying atop, and covering, the second bullet such that an interior of the inner casing is divided to form a gunpowder chamber. 2. The rocket structure of claim 1, wherein the outer casing comprises an outer casing body and a cap lying atop, and covering, the outer casing body. 3. The rocket structure of claim 2, wherein the inner casing comprises an inner casing body and a lid lying atop, and covering, the inner casing body. 4. The rocket structure of claim 1, wherein the bottom of the outer casing has a plurality of inclined propulsion-gas outlet holes. 5. The rocket structure of claim 4, wherein the propulsion-gas outlet holes in the bottom of the outer casing are each inclined at 20 degrees. 6. The rocket structure of claim 1, wherein the bottom of the inner casing has a plurality of vertical vent holes. 7. The rocket structure of claim 1, wherein the first bullet is peripherally provided with a plurality of first air holes, and a plastic tube with first gunpowder received therein is placed in the first bullet. 8. The rocket structure of claim 1, wherein the second bullet has second gunpowder placed therein, is peripherally provided with a plurality of second air holes, and has a bottom with a through bore in communication with the second supporting member, and the second air holes and the through bore are smaller than particles of the second gunpowder.
