1. A mechanical magazine, comprising:
a casing, the casing comprising an ammunition inlet, an ammunition outlet, and an ammunition passage extending from the ammunition inlet to the ammunition outlet; and
a mechanical driver, the mechanical driver comprising a rotation disc and an energy storage unit;
wherein,
the mechanical driver is disposed on one side of the casing and is configured to drive ammunition rounds to move from the ammunition inlet to the ammunition outlet and to be ejected out of the casing;
the rotation disc is rotationally connected to the casing to push the ammunition rounds to move along the ammunition passage;
the energy storage unit is disposed on the rotation disc, and when the rotation disc rotates relative to the casing, the energy storage unit is subjected to elastic deformation to store or release energy;
when in use, the rotation disc rotates in a direction towards the ammunition inlet, the energy storage unit is compressed to save energy; when the energy is released, the energy storage unit drives the rotation disc to rotate in a direction towards the ammunition outlet, causing the ammunition rounds to move in the direction towards the ammunition outlet and to be ejected out of the casing;
the ammunition passage comprises a multiple-round passage, a single-round passage, and a conversion space connecting the multiple-round passage and the single-round passage; the single-round passage surrounds the rotation disc and extends from the conversion space to the ammunition outlet; and a guide disc is disposed in the multiple-round passage to guide the ammunition rounds in the multiple-round passage to the single-round passage one by one; and
the mechanical driver further comprises a transmission gear coaxially disposed with the rotation disc; the guide disc is meshed with the transmission gear and comprises a plurality of protrusion groups; the plurality of protrusion groups are radially spaced apart on the guide disc; each of the plurality of protrusion groups comprises a plurality of protrusions circumferentially spaced apart on the guide disc; the plurality of protrusions in a first protrusion group are misaligned with the plurality of protrusions in a second protrusion group in a circumferential direction of the guide disc to form a plurality of gaps; the second protrusion group is adjacent to the first protrusion group, and each gap allows a single ammunition round to pass through one time.
