A hand-held cracker snap spraying projectile includes a main unit, a press element, a suppression disk, an air cylinder and a nozzle. The main unit is a housing object, the press element is loosely disposed in the through-hole, the suppression disk is disposed in the main unit and is connected with the press element. The air cylinder is disposed in the main unit and is provided with a corrugated central tube, allowing the air cylinder to be extended or shortened along the central axis repeatedly to attract or squeeze air to enter or exit the air cylinder. The nozzle is a tube object in the connecting pipe, and an end of the nozzle is connected with the interior part of the air cylinder, allowing air to pass through the nozzle to enter or exit the air cylinder. The nozzle guides air into the bullet. |

1. A hand-held cracker snap spraying projectile, comprising a main unit, a press element, a suppression disk, an air cylinder and a nozzle, wherein the main unit is a housing object, the top end of the main unit is formed with a through-hole, the periphery of the through-hole is formed with an annular restraint part, the bottom rim at one side of the main unit is protruded laterally with a connecting pipe, and the interior of the connecting pipe is provided radially with a loop-shaped stop part; the press element is a tube object with a sealed end, the press element is loosely disposed in the through-hole, an end of the press element is formed with a top plate outside the main unit, and the other end of the press element is extended into the through-hole to form an orifice end; the suppression disk is disposed in the main unit, the rim of the suppression disk is in adjacent to the restraint part, the restraint part forms stop to the suppression disk along one direction, and the suppression disk is connected with the orifice end; the air cylinder is disposed in the main unit, the air cylinder is a circular cylinder made of an elastically deformable material, the top end of the air cylinder is formed with a flat pressure bearing plate, the bottom end of the air cylinder is formed with a bottom plate, a central tube is formed between the pressure bearing plate and the bottom plate, the pressure bearing plate is in adjacent to the bottom rim of the suppression disk, the bottom plate is in adjacent to the top rim of the bottom seat, and the central tube is corrugated along the direction pointing to the pressure bearing plate and the bottom plate, so that the air cylinder is elastically extended or shortened along the central axis repeatedly, thereby attracting or squeezing air into or out of the air cylinder; the nozzle is a tube object in the connecting pipe, an end of the nozzle is connected with the bottom part at the side rim of the air cylinder and is connected with the interior part of the air cylinder to allow air to enter or exit the air cylinder through the nozzle, the other end of the nozzle is extended into the loop-shaped space of the stop part, and a terminal end of the nozzle is formed with a cone-shaped guide part which is used to guide a bullet to sheath with the nozzle. |
