A toy missile projector comprises a tubular missile body, an outer tube and an inner tube placed within the missile body such that the outer tube is fixed to an annular groove on the missile body and maintains contact with a reset spring located in the annular groove. A piston is mounted in the lower end of the missile body, a compression spring is placed in an axial hole at the end of the piston rod, a spring and a movable pin is placed in a longitudinal key way on the outer wall of the piston body such that the movable pin is aligned with a stop hole on the missile body so that when a launching button at the stop hole is triggered, the compression spring is released and the piston rod is displaced rapidly for firing. The missile body can be formed in three sections-first, intermediate, and last outer tubes, and assembled with a guide tube and a piston rod and with a reset spring placed between the guide tube and the last outer tube. A compression spring is placed at the bottom of the piston rod, the last outer tube can be displaced within the guide tube, and the movable pin at the piston rod can be seized by the launching button so that the compression spring is compressed by the piston rod and a compressed air zone is formed in the intermediate tube to provide a large thrust force when the launching button is pushed.
