A hand-held cracker snap for spraying projectile includes a main unit, a button, a disk, an air cylinder and a nozzle. The button is loosely disposed in the main unit. The disk is disposed in the main unit and is connected to the button. The air cylinder is disposed in the main unit and is provided with a central tube that can be extended or compressed along an axis repeatedly to suck or squeeze air to or from the air cylinder. The nozzle is a tubular element in the connecting pipe. An end of the nozzle is connected to the interior part of the air cylinder, allowing air to enter or exit the air cylinder via the nozzle. The nozzle guides air into the bullet.

1. A hand-held cracker snap comprising: a main unit comprising an aperture at an upper end, an annular restraint formed on a wall the aperture, a connecting pipe extending from a lower portion, and an annular stop extending on an internal face of the connecting pipe;a press element comprising an upper end located out of the body, a lower end located in the main unit, a top plate formed at the upper end, and an orifice made in the lower end;a disk inserted in the main unit and connected to the lower end of the button, wherein the restraint is adapted for abutment against a rim of the disk, thereby restraining the disk in a sense of direction;an air cylinder inserted in the main unit, made of an elastic material, and formed with a pressure bearing plate at an upper end, a bottom plate at lower end, and a central tube between the pressure bearing plate and the bottom plate, wherein the pressure bearing plate is adjacent to a lower face of the disk, the bottom plate supported on a portion of the main unit, the central tube is elastically extensible to suck air therein, and the central tube is elastically compressible to squeeze out the air; anda nozzle extending in the connecting pipe from a lower portion of the air cylinder so that the air enters or leaves the air cylinder via the nozzle, and comprising a first end on a side of the annular stop, a second end on another side of the annular stop, and a conical guide formed at the second end and adapted for guiding a bullet that contains projectile. 2. The hand-held cracker snap according to claim 1, wherein the disk is made with an external diameter larger than a diameter of the aperture, the disk comprises a shallow cavity for receiving and hence confining the pressure bearing plate, and the main unit comprises an arc-shaped wall that extends around and hence confines the bottom plate. 3. The hand-held cracker snap according to claim 2, wherein the arc-shaped wall extends a long an arc with a radius R, the arc-shaped wall comprises two ends at a distance L from each other, and L is smaller than 2R. 4. The hand-held cracker snap according to claim 1, further comprising a band connected to the main unit and adapted for wrapping an external article. 5. The hand-held cracker snap according to claim 4, wherein the fastener is a hook-and-loop fastener. 6. The hand-held cracker snap according to claim 1, wherein the main unit comprises: a body comprising a first semi-tube and first semi-ring formed on an internal face of the first semi-tube; anda base connected to the body and formed with a second semi-tube and second semi-ring on an internal face of the second semi-tube, wherein the first and second semi-tubes are joined together to form the connecting pipe, and the first and second semi-rings are joined together to form the annular restraint. 7. The hand-held cracker snap according to claim 1, wherein the button comprises a first tube extending toward the main unit from the top plate, the suppression disk comprises a second tube extending toward the first tube and an annular rib extending around the second tube, the annular rib is inserted in the press element via the orifice, an external face of the annular rib is adjacent to an internal face of the button, the button is connected to the disk by a bolt inserted in the first and second tubes.
