It will be appreciated that as shown in fig. 3 and 4, the locking link 301 and the positioning link 2031 are both connected to the drive disc 202 via a rotating fulcrum bar, i.e., the locking link 301 and the positioning link 2031 share a common drive mechanism 201, and the locking assembly 30 and the positioning assembly 20 are movable in unison.

Specifically, when the driving rod 2012 is driven by the driving motor 2011 to drive the driving disc 202 to move upward, the positioning connecting rod 2031 extends outward, the positioning pushing plate 2035 pushes the circular ring-shaped supporting leg 21 to move so as to center the circular ring-shaped supporting leg 21, meanwhile, the locking connecting rod 301 swings downward, the latch 302 gradually approaches the circular ring-shaped supporting leg 21, when the positioning pushing plate 2035 pushes the circular ring-shaped supporting leg 21 to complete the centering, the locking connecting rod 301 swings in place at the same time, and the latch 302 fastens the circular ring-shaped supporting leg 21 on the supporting plate 10.

Further, when the unmanned aerial vehicle needs to take off, the driving motor 2011 drives the driving rod 2012 to drive the driving disc 202 to move downwards, the positioning connecting rod 2031 retracts, and meanwhile, the locking connecting rod 301 swings upwards to complete the release of the circular ring-shaped supporting leg 21.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; may be mechanically coupled, may be electrically coupled or may be in communication with each other; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

In the present disclosure, the terms "one embodiment," "some embodiments," "an example," "a specific example," or "some examples" and the like mean that a specific feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present disclosure. In this specification, the schematic representations of the terms used above are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.

Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art within the scope of the present invention.
