[0026] The adjustment mechanism 3 includes a slot frame 301, which is fixed to the end of the mounting assembly 4, and a rotating rod 302 is engaged inside the slot frame 301, wherein the slot frame 301 is a semi-enclosed structure, the outer wall of the rotating rod 302 is in contact with the inner wall of the slot frame 301, and shafts 303 are fixedly connected to both ends of the rotating rod 302, and a motor 304 is connected to the top of the upper shaft 303, and a protective frame 305 is sleeved on the outside of the motor 304. The utility model effectively drives the shaft 303 and the rotating rod 302 to rotate through the motor 304, thereby driving the limiting structure 2 on one side of the rotating rod 302 and the ducted fan body 1 to rotate, effectively switching the state of the ducted fan body 1 to adapt to the operating environment of the land-air amphibious transporter and improve the practicality of the device.

[0027] It is worth noting that the limiting structure 2 includes a fixed ring frame 201, which is fixedly mounted on the outside of the ducted fan body 1, and a movable frame 202 is attached to the rear of the fixed ring frame 201. Bolts 203 penetrate the inside of the fixed ring frame 201 and the movable frame 202, and a hexagonal nut 204 is screwed on the outside of the bolt 203. The movable frame 202 is mounted on the outside of the ducted fan body 1, and the fixed ring frame 201 forms a detachable structure with the movable frame 202 through the bolts 203 and the hexagonal nuts 204, and a drainage groove 205 is opened on the surface of the movable frame 202. The utility model effectively connects the fixed ring frame 201 with the movable frame 202 through the bolts 203 and the hexagonal nuts 204, thereby realizing the connection between the ducted fan body 1 and the limiting structure 2, making it convenient for the ducted fan body 1 to switch its own state as the limiting structure 2 is adjusted. The setting of the drainage groove 205 can guide the high-speed airflow, reduce the resistance of the movable frame 202, and improve the connection stability of the movable frame 202, thereby improving the stability of the ducted fan body 1.

[0028] It is worth noting that the mounting assembly 4 includes a positioning frame 401, which is fixed to the outside of the slot frame 301, wherein the positioning frame 401 and the slot frame 301 are integrally formed, the slot frame 301 is L-shaped, a set of drainage grooves 2 402 are provided on the surface of the positioning frame 401, a reinforcement plate 403 is provided on the inner side of the positioning frame 401, and a drainage groove 3 404 is provided on the surface of the reinforcement plate 403.

[0029] Working principle: When the land-to-air amphibian transporter is running in the air, the motor 304 drives the shaft 303 and the rotating rod 302 to rotate, thereby driving the limiting structure 2 and the ducted fan body 1 on one side of the rotating rod 302 to rotate, and the ducted fan body 1 is rotated out to enable the land-to-air amphibian transporter to be propelled. At this time, the drainage groove 1 205 can guide the high-speed airflow, reduce the resistance of the movable frame 202, and improve the connection stability of the movable frame 202, thereby improving the stability of the ducted fan body 1. When the land-to-air amphibian transporter is running on land, the motor 304 drives the shaft 303 and the rotating rod 302 to rotate, thereby driving the limiting structure 2 and the ducted fan body 1 on one side of the rotating rod 302 to rotate, and the ducted fan body 1 is folded to reduce resistance and occupy space. When the land-to-air amphibian transporter is running in the air or on land, the drainage groove 2 402 and the drainage groove 3 404 both guide the high-speed airflow, reduce the resistance of the positioning frame 401, and improve the overall installation stability of the device.
