Dispersion locking type rudderstock structure

The invention discloses a decentralized locking type rudderstock structure. The decentralized locking type rudderstock structure comprises a decentralized locking mechanism; a dispersed locking mechanism is additionally arranged, a lower linkage screw rod is mounted on the outer side of the lower end of each radial abutting plate, the outer end of each lower linkage screw rod extends into a locking groove through a connecting channel, and meanwhile, a screwing nut is screwed to the outer end of each lower linkage screw rod in a threaded mode; in this way, the screwing nut is rotationally connected to the end face of the inner side of the locking groove in an abutting mode, the radial structural stability of the floating protruding blocks is improved, each floating protruding block is provided with an independent locking structure, the locking structures are evenly dispersed, and therefore even if the radial structures of the individual floating protruding blocks are loosened towards the inner side, the floati
