Toy gun

The utility model relates to a toy gun. The toy gun comprises a push rod and a gun cylinder, wherein a rectilinear bullet passage hole communicated from front to back is formed in the gun cylinder, and the push rod can be inserted into the bullet passage hole to form a front-back telescopic match with the gun cylinder. The toy gun is characterized in that the bullet passage hole comprises a bullet inlet and a bullet outlet, a first bullet and a second bullet are arranged in the bullet passage hole in sealing fit with the inner wall of the bullet passage hole, the first bullet and the second bullet are capable of sliding relative to the bullet passage hole under the action of thrust, the first bullet and the second bullet are made of lightweight materials and arranged at intervals with each other, and the length of the push rod is 2-5 cm less than the length of the bullet passage hole. The second bullet is driven quickly by the exertion of enough force on the push rod, therefore, the air between the first bullet and the second bullet is compressed within a short time, and the first bullet is catapulted out when the pressure of the air is lager than the friction between the first bullet and the bullet passage hole. The toy gun has the advantages of being simple in structure, low in production cost and easy to operate.
