The front hub and the rear hub are connected by a first fastener and are both disc-shaped. A columnar limiting cavity is formed between the front hub and the rear hub. A front axle hole and a rear axle hole are respectively provided at the axis of the front hub and the rear hub. The limiting cavity, the front axle hole and the rear axle hole are located on the same axis and can be passed through by the propeller shaft. A plurality of through holes connected to the limiting cavity are also formed between the front hub and the rear hub. All the through holes are evenly distributed radially with the axis of the front axle hole as the center. The number of blades is equal to the number of through holes. The blades include a blade portion, a root portion and a limiting portion connected in sequence. The cross-section of the limiting portion is fan-shaped. All the limiting portions form an annular structure limited to the limiting cavity.

[0027] The adjustment mechanism 2 includes a connecting shell 21, inside of which a No. 3 connecting shaft 26 is fixedly connected, the surface of the No. 3 connecting shaft 26 is slidably connected to a limit block 211, the upper part of the limit block 211 is fixedly connected to a mounting frame 28, the surface of the mounting frame 28 is movably connected to a No. 1 adjusting shaft 29, one end of the No. 1 adjusting shaft 29 is movably connected to a No. 2 adjusting shaft 210, one end of the No. 2 adjusting shaft 210 is fixedly connected to an adjustment plate 27, the surface of the adjustment plate 27 is fixedly connected to a No. 2 connecting shaft 22, the No. 2 connecting shaft 22 is rotatably connected to the connecting shell 21, and the surface of the No. 2 connecting shaft 22 is fixedly connected to a paddle 25.
[0028] The specific configuration and function of this embodiment are described in detail below. The No. 1 connecting plate 11 is fixedly mounted on the hull, and the No. 1 connecting shaft 15 is fixedly mounted on the rotating output shaft of the propeller. The No. 1 connecting shaft 15 is driven to rotate by rotating the output shaft. At this time, the No. 1 connecting shaft 15 drives the No. 3 connecting shaft 26 and the connecting shell 21 to rotate. Under the rotation of the connecting shell 21, the external blades 25 are driven to rotate, thereby driving the hull to move.
[0029] When the paddle blades 25 drive the hull to move, when the thrust generated by the paddle blades 25 needs to be adjusted under the same rotation speed, the No. 2 connecting plate 13 and the connecting frame 14 are driven to move by the telescopic electro-hydraulic push rod 12. When the connecting frame 14 starts to move, the connecting frame 14 will drive the mounting frame 28 to slide along the No. 3 connecting shaft 26, thereby driving the No. 1 adjusting shaft 29 to swing in a fan shape along the surface of the mounting frame 28, and at the same time drive the No. 2 adjusting shaft 210 to move in an arc.

[0034] When the propeller 25 drives the hull to move, when the thrust generated by the propeller 25 needs to be adjusted under the same rotation speed, the No. 2 connecting plate 13 and the connecting frame 14 are driven to move by the telescopic electro-hydraulic push rod 12. When the connecting frame 14 starts to move, the connecting frame 14 drives the mounting frame 28 to slide along the No. 3 connecting shaft 26, thereby driving the No. 1 adjusting shaft 29 to swing in a fan shape along the surface of the mounting frame 28, and driving the No. 2 adjusting shaft 210 to move in an arc. The No. 2 adjusting shaft 210 drives the adjusting plate 27 and the No. 2 connecting shaft 22 to rotate along the connecting shell 21.

[0035] When the second connecting shaft 22 rotates along the connecting shell 21, the annular slider 24 slides along the annular slide rail 23 to limit the rotation of the second connecting shaft 22. When the mounting frame 28 slides along the surface of the third connecting shaft 26, the limit block 211 slides along the limit groove 212.
