The inner side of the extrusion frame 49 is fixedly provided with a spring 410 and a damper 411. The bottom surfaces of the spring 410 and the damper 411 are fixedly connected to the top surface of the fixed frame 48. The spring 410 is initially in an extended state. The outer wall of the moving block 43 is fixedly connected to the outer walls of the two connecting frames 45 respectively. The inner sides of the two connecting frames 45 are respectively provided with two rotating rollers 46 through two sets of bearing seats. The outer walls of the two rotating rollers 46 are fixedly connected to the inner sides of the two sets of suction cups 47 respectively. The outer walls of the two sets of suction cups 47 are in contact with the top surface of the connecting plate 1.

[0035] The transmission mechanism 3 includes a fixed frame 36, the bottom surface of which is fixedly connected to the bottom surface of the connecting plate 1. A rotating rod 32 is rotatably mounted on the inner side of the fixed frame 36 via two bearing seats. Two control frames 35 are fixedly sleeved on the outer wall of the rotating rod 32. The side of the two control frames 35 closest to the tail fin 5 is fixedly connected to the bottom surface of the tail fin 5. A fixed sleeve 31 is fixedly mounted on the inner side of the fixed frame 36, and the inner side of the fixed sleeve 31 is rotatably connected to the outer wall of the rotating rod 32. Two wedge-shaped grooves are formed on the top surface of the connecting plate 1, and two wedge-shaped blocks 39 are slidably mounted on the inner walls of the two wedge-shaped grooves.

When the moving block 43 moves, it can cause the two rotating rollers 46 to rotate. When the two rotating rollers 46 rotate, they can drive the two sets of suction cups 47 to rotate synchronously. When the two sets of suction cups 47 rotate, they can further increase the resistance of the moving block 43, thereby providing auxiliary reinforcement to the tail fin.
