Rotation translation supporting mechanism with damping servo

The invention relates to a rotation translation supporting mechanism with damping servo, comprising a rotation translation support, a transition connecting plate and a carrier connecting base. The rotation translation supporting mechanism is characterized in that a center shaft is arranged between the rotation translation support and the carrier connecting base and penetrates the transition connecting plate, the threaded hole at the lower part of the side of the rotation translation support is internally provided with an adjusting screw, and a damping spring is arranged between the center shaft and the adjusting screw. The rotation translation support of the invention can realize rotation and translation relative to the center shaft and carrier connecting base along with projectile body, does not extrude the projectile body and ensures the surface of projectile body to be non-deformed in rearming process and solves the problems that the original whole carrier is large in volume and heavy in weight and is easy
