  • Patent number: 9404703
    Abstract: A feeding and positioning device for toy gun comprises a barrel and a friction cylinder. The barrel has a bore, a convex hole, and a guiding groove. Two groove sides are formed at two sides of the guiding groove with circular cone shape. A width and a depth of the guiding groove are gradually decreased from the first end of the barrel inwardly. The friction cylinder has a hollow and elastic cylinder body covered at the first end of the barrel and a friction portion arranged inside the cylinder portion and inserted into the convex hole inwardly. The bullet is aligned by the groove sides and then cooperated with the friction portion to form three-point guiding position to downwardly press the bullet to be precisely fed. It may prevent the bullet from skewed error and improve the range of firing, effective potential energy, and hit rate.
