When the extractor works, the sliding body moves vertically relative to the fixed base. A first external threaded column and an internal threaded sleeve are respectively fixed on the lower surface of the sliding body and the upper surface of the fixed base. The ammunition body includes a charge cartridge and a projectile connected to each other. A saddle-shaped card seat is fixed on the projectile. The extracting structure further includes an extracting base, a connecting body, an inner pull sleeve and an outer sleeve. A second external threaded column meshing with the internal threaded sleeve is fixed at the bottom of the extracting base. The bottom of the charge cartridge is movably connected to the extracting base. A cavity is provided in the center of the inner pull sleeve. The card seat and the connecting body are clamped in the cavity. A through hole is provided in the center of the connecting body, and an internal threaded hole meshing with the first external threaded column is provided above the through hole. The outer sleeve is movably sleeved outside the inner pull sleeve.

[0005] Preferably, an opening is provided on one side of the extracting base, and a chute is provided inside the extracting base. A flange adapted to the chute is integrally formed at the bottom of the charge cartridge.

[0006] Preferably, the inner pull sleeve is composed of two mutually separated semi-circular structures.

[0007] Preferably, an inner inclined conical surface is provided at the lower part of the cavity, and the conical surface is adapted to the card seat.
