  • Bullet aligning device
    Patent number: 11150043
    Abstract: A bullet aligning device in which the bullet on the turntable can be thrown to the periphery of the turntable through centrifugal force and sent out through the bullet outlet, and the adjacent wall of the bullet outlet is provided with a through groove, the height of the through groove is slightly smaller than the diameter of the bullet to prevent two or more bullets from jamming the bullet outlet to ensure the smooth delivery of bullets. The bullet aligning device uses the directional track arrangement to allow only one bullet to enter the guide groove at a time to give each bullet enough time and space to fall, so that the bullets choose the heavier tail to fall into the direction-correcting guide slot, and the bullets in the same direction are exported from the one-way export slot.

  • Bullet reload device
    Patent number: 11125518
    Abstract: A bullet reload device includes a base, a roller seat, a roller and a flexible connection member. The grooves formed between the blades of the roller only let the bullets in the correct direction fall in, so that the bullets in the correct direction can move in a row. The line-up track of the base has a guide rail set therein, so that the extractor grooves of bullets can follow the guide rail to scroll from top to bottom in the line-up track without turning the direction, and thus, bullets can be neatly arranged in the line-up track. The flexible connection member is provided with a pressure plate connected to the roller seat by tension springs, so that pressing the pressure plate with the palm can conveniently apply force to move the flexible connection member downward along the non-linear line-up track to push the bullets into the magazine.
