Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing of the present utility model, provide the description of specific embodiment, but not as to any restriction of the present utility model.

Seeing Fig. 2～Fig. 5, bullet, including bullet 1, shell case 2, gunpowder 3 and ignition device 4, one end of bullet 1 is inlaid in the faucal 2-1 of shell case 2, ignition device 4 is inlaid on the shell head 2-2 of shell case 2, and gunpowder 3 is arranged in shell case 2, and one end of gunpowder 3 contacts with ignition device 4；

One end of bullet 1 is streamlined, and the other end of bullet 2 is circular arc.

Further, bullet 1 is that two ends are streamlined, reduces the air resistance to bullet 1.

Further, shell case 2 includes collet 5, and collet 5 is between bullet 1 and gunpowder 3.

Further, collet 5 is embedded at the shell neck 2-3 and shoulder 2-4 of shell case 2.

Further, one end of collet 5 offers groove 6, groove 6 is del, one end of bullet 1 is arranged in the inverted triangular-shaped grooves 6 of collet 5, and the both sides of inverted triangular-shaped grooves contact with streamlined bullet 1, thus adds bullet 1 base pressure stress surface, reduce the bullet 1 tolerance in gun barrel, prevent high energy gas from leaking reduction kinetic energy, it is ensured that the streamline profile that bullet 1 is smooth, decrease the air resistance to bullet 1.

Further, gunpowder 3 includes one-level gunpowder 3-1 and two grades of gunpowder 3-2, and one end of one-level gunpowder 3-1 is connected with ignition device 4, and the other end and two grades of gunpowder 3-2 of one-level gunpowder 3-1 are connected, and two grades of gunpowder 3-2 are arranged between one-level gunpowder 3-1 and collet 5.

Further, the power of two grades of gunpowder 3-2 is better than the power of one-level gunpowder 3-1, improves the overall power of gunpowder.

Further, one-level gunpowder 3-1 is common gunpowder, in bulk in shell case 2；Two grades of gunpowder 3-2 are hexogen, are processed to solid-state and are arranged in shell case 2.Two grades of gunpowder 3-2 replace the part primary gunpowder 3-1 used in prior art, with one-level gunpowder with the use of, improve the brisance of gunpowder, cause the increase of described bullet kinetic energy, thus improve the flight speed of bullet, improve the flight stability of bullet, improve the effective range of bullet, reduce curved trajectory degree, improve fire accuracy.Any gunpowder 3 that can meet requirement all falls within protection domain of the present utility model.

Further, two grades of gunpowder 3-2 are arrow-shaped, and the arrow end of two grades of gunpowder 3-2 contacts with one-level gunpowder 3-1, and the other end of two grades of gunpowder 3-2 and collet 5 surround a confined space in shell case 2.

Specifically, two grades of gunpowder 3-2 are processed to solid-state arrow-shaped, form propellant of high energy energy gathering cap, at gunpowder 3 explosion time, ensure that the energy of abrupt release is concentrated in the other end of two grades of gunpowder 3-2 surrounds a confined space with collet 5 in shell case 2 and act on collet 5, thus bullet 1 is quickly propelled out muzzle and aloft flies, reduce bullet resistance, improve the kinetic energy of bullet, enhance the penetration power of bullet.

The technical solution of the utility model is achieved in that

In the moment that ignition device 4 is ignited, one-level gunpowder 3-1 and the two grades of gunpowder 3-2 being processed to arrow-shaped energy gathering cap are detonated successively, gunpowder 3 is exploded the high heat of generation, gases at high pressure energy at a high speed to centre gathering by two hypotenuses of two grades of gunpowder 3-2 arrows, and concentration acts on collet 5, improve the kinetic energy of bullet；It is streamlined due to bullet 1 again, one end of bullet 1 is arranged in groove collet 5, groove collet 5 gunpowder 3 being subject to is exploded produce kinetic energy act on bullet 1, bullet 1 is quickly propelled out muzzle and aloft flies, meanwhile, groove collet 5 departs from shell case 2, bullet 1 after flying out along with bullet 1 simultaneously, fall at the periphery of user, effectively reduce the air resistance to bullet 1, improve flight speed and the effective range of bullet, enhance the stability of trajectory, improve the penetration power of bullet.
