Modularized front foldable stabilizing fin executing mechanism

The present invention relates to a modularized forwards-folding type fin stabilizer executing mechanism which mainly solves the technical problems of improving the operating performance of the executing mechanism, reducing the manufacturing and assembling cost, etc. The technical proposal is that: the mechanism is provided with a fin box; the fin box consists of an upper plate, a lower plate, a front upper plate, a front lower plate, shear strakes and side plates which are combined as a whole. The box is provided with a fin box opening. The inner cavity of the fin box is an inner watertight cavity. The lower plate and the front lower plate of the fin box are respectively connected with corresponding components of a hull in a fixed way. The side plates are provided with retractable link stoppers which are corresponding to a lug boss of a crosshead component. The modularized forwards-folding type fin stabilizer executing mechanism is fit for various forwards-folding type fin stabilizer devices.
