The invention relates to a warped swing type structure of a propeller for a ship. The structure comprises a base connected to a ship rail and a movable base used for being connected with a hanging rod. The movable base can rotate relative to the base. The structure is characterized in that a spring bolt is also fixed to a bottom plate of the base, the movable base is rotationally provided with a locking block, the locking block is provided with a toothed groove matched with the spring bolt, and when the toothed groove of the locking block meshes with the spring bolt and is in a locked state, the movable base is kept at the position where the hanging rod is in a vertical state; when the toothed groove of the locking block is separated from the spring bolt and in an unlocked state, the movable base can warp, swing and rotate relative to be base. It is clear that the movable base can rotate relative to the base only in the unlocked state, and the propeller is driven to turn over and leave the water surface; the locking block and the spring bolt are located on the ship rail, so the locking block is very convenient to drive. The whole structure is simple, the cost is low, and accordingly the structure is very worthy of application and popularization on existing ships, especially on small ships like kayaks.
