[0025] Specifically, the fixed seat 8 is used to support and fix the bottom end of the adjusting plate 13. The adjusting plate 13 together with the deflector 14 can be removed through the pins 7. The pressing rods 1 are used to slide inside the fixed seat 8, and support frames 2 are fixedly connected to the outer periphery. By operating the pressing rods 1, the disassembly mechanism can be triggered for disassembly. The support frames 2 are used to support the pressing rods 1 to ensure their stability during movement. The connecting rod one 3 is used to connect the support frames 2 and the moving frame 10 to ensure their coordinated operation. The moving frame 10 is used to be fixedly connected to the fixed end of the connecting rod one 3, and a sliding rod 9 is slidably connected to the other end, which can work together with other components to realize the movement of disassembly. The sliding rod 9 is used to be fixedly connected to the sliding end of the moving frame 10 and can perform the movement work of removing the adjusting plate 13. The fixed rod 6 is used to fixedly connect the two pressing rods 1 on the side facing each other and can participate in the disassembly movement mechanism of the pressing rods 1.

[0026] Refer to Figure 1-2 , the driving component includes a support plate 24, the support plate 24 is fixedly connected to one side of the adjusting plate 13, a motor 17 is fixedly connected to the inner side of the support plate 24, a runner 16 is rotatably connected to the driving end of the motor 17, a belt 15 is slidably connected to the outer periphery of the runner 16, an adjusting component is arranged on one side of the runner 16, the adjusting component includes two adjusting rods 23, both of the two adjusting rods 23 are fixedly connected to one end of the runner 16, deflectors 14 are fixedly connected to one side of the two adjusting rods 23, and landing gears 22 are fixedly connected to both sides of the fuselage 18.
