A scheme that a rudder system with a wing spreading locking function pushes rudder sheets to spread simultaneously and lock the rudder sheets is adopted by the invention. After a rocket projectile is launched, the rudder system is powered by a missile-borne controller; after a rudder spreading command is emitted, the rudder system controller receives the rudder spreading command of the missile-borne control system; current amplification is performed after the rudder system controller receives a rudder spreading command signal, so that a pin pusher is started, and a pushing disc is pushed to spread the four rudder sheets simultaneously; after spreading angles reach 90 degrees, limiting is performed through the locking mechanism, and the whole wing spreading locking function is finished; and then, the missile-borne controller gives a rudder deflecting command, so that a rudder engine is controlled to drive the rudder sheets to swing, and a servo control function is realized. Meanwhile, for ensuring that the sailing posture of the rocket projectile is not affected, the spreading time of the four rudder sheets is very short and the asynchronism of spreading is very low.
