[0028] The thruster steering seat 11 has a cross-shaped structure, with a thruster nozzle connection flange at the center. Four evenly distributed universal joint connecting arms are arranged on the periphery of the thruster nozzle connection flange, and a universal joint 12 is fixedly connected to each universal joint connecting arm by screws.

[0029] The outer periphery of the propeller nozzle 21 is provided with a propeller steering seat connection flange, and screws penetrate the propeller nozzle connection flange of the propeller steering seat 11 and the propeller steering seat connection flange of the propeller nozzle 21 to fix the propeller steering seat 11 with the propeller nozzle 21.
