Simulated projectile launching system

A simulated projectile launching system comprises a traction mechanism, a push-pull buffer mechanism, a high-low angle adjusting mechanism and a barrel. The traction mechanism is arranged at the front end of the body tube, the push-pull buffering mechanism comprises a sleeving unit arranged on the body tube in a sleeving mode and a second driving part for driving the sleeving unit to move back and forth relative to the body tube, and the second driving part is fixed to the rear end of the body tube; the high-low angle adjusting mechanism is fixed on the sleeving unit; and the high-low angle adjusting mechanism is fixed on the sleeving unit and is used for supporting the barrel. According to the application, the traction mechanism is used for simulating that the projectile enters and exits from the chamber, the push-pull buffer mechanism is used for simulating the counter-acting force in the projectile launching process, the high-low angle adjusting mechanism enables the whole system to be still relatively sta
