Cradle head bullet passing mechanism based on spring hinge driven sliding opening

The invention discloses a cradle head bullet passing mechanism based on a spring hinge driven sliding opening. The cradle head bullet passing mechanism comprises a cradle head bullet passing pipeline, a launching front end pipeline, the spring hinge driven sliding opening and a pipeline rear end limiting device, the sliding opening and the pipeline rear end limiting device are arranged on the cradle head bullet passing pipeline, a bullet passes through the sliding opening and the pipeline rear end limiting device in sequence, and finally, the bullet enters the launching front end pipeline. According to the cradle head bullet passing mechanism, smooth connection of a launching mechanism and the cradle head pipeline can be achieved, so that the bullet is in smooth transition before entering the launching device through the cradle head pipeline, and the bullet cannot be blocked when moving in the pipeline. Compared with an existing cradle head bullet passing pipeline connecting sliding opening, the cradle head b
