[0031] As a specific embodiment of the present invention, the configurable drone mouth cover mechanism further includes a plurality of first fixing members, and the first guide block 221 and the second guide block 222 are both fixedly connected to the mouth cover 10 through the first fixing members. In this embodiment, the first fixing member can be a countersunk rivet. The selection of the above-mentioned first fixing member is only an example, but is not limited thereto.

[0032] Further, in the present invention, if Figure 4 and Figure 5 As shown, in order to facilitate the rotatable connection between the plurality of cover fixing ear claws 40 and the rotating base 30, the rotating base 30 may be configured to include a central column 31 and a plurality of connecting rods 32, wherein the central column 31 is connected to the plurality of connecting rods 32, and the plurality of connecting rods 32 are rotatably connected to the plurality of cover fixing ear claws 40 in a one-to-one correspondence. When the cover 10 needs to be closed or opened, the plurality of connecting rods 32 are driven to rotate by rotating the central column 31, and the cover fixing ear claws 40 rotate relative to the connecting rods 32 around the connection position between the connecting rods 32 and the cover fixing ear claws 40 under the guide limit of the guide assembly 22, so as to realize the extension or retraction of the cover fixing ear claws 40.

[0035] As another specific embodiment of the present invention, Figure 4 As shown, in order to facilitate the rotation operation of the center column 31, the center column 31 can be configured to have a groove 31a at one end facing the mouth cover 10, and the mouth cover 10 has a first through hole 10a. The groove 31a corresponds to the position of the first through hole 10a, and the groove 31a is used to place an external tool to drive the rotating base 30 to rotate. For example, the groove 31a can be set as a hexagonal hole, and the rotating base 30 can be easily rotated using a standard hexagonal tool. The setting of the above groove 31a is only an example of a rotationally driven rotating base, but is not limited to this.

[0036] Further, in the present invention, if Figure 1 and Figure 6As shown, in order to realize the smooth rotation of the rotating base 30, the drone cover mechanism can be configured to further include a sliding bearing 50, which is sleeved on one end of the middle column 31 of the rotating base 30 facing the fixed frame body 21, and the sliding bearing 50 is located between the middle column 31 and the fixed frame body 21. By arranging the sliding bearing 50 between the middle column 31 of the rotating base 30 and the fixed frame body 21, on the one hand, the reliability of the sliding between the rotating base 30 and the fixed frame body 21 is guaranteed, and on the other hand, the bearing shape can be independently designed to ensure the smooth rotation between the rotating base 30 and the fixed frame body 21.
