DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more.

[0022] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-3 , a guiding mechanism for a plastic part of a drone main body, including a storage cover 1, a storage body 2, a guiding rod 3, and a connecting cylinder 4. Among them, the guiding rod 3 is connected to the lower edge of the storage cover 1, and a plurality of guiding rods 3 are evenly distributed along the outer edge of the storage cover 1. The storage cover 1 and the guiding rod 3 are integrally injection-molded. The connecting cylinder 4 is connected to the lower edge of the storage body 2, and the connecting cylinder 4 corresponds to the guiding rod 3 one by one. The connecting cylinder 4 and the storage body 2 are integrally injection-molded. When the storage cover 1 and the storage body 2 are butted and fastened up and down, the guiding rod 3 penetrates through the connecting cylinder 4. Further, the lower end of the guiding rod 3 is chamfered to form a conical structure, which is convenient for inserting into the connecting cylinder 4. A nut 5 is screwed on the outer thread of the connecting cylinder 4. A plurality of inclined shrinking pieces 41 are arranged along the circumference at the lower end of the connecting cylinder 4. A shrinking gap 42 that is narrower at the top and wider at the bottom is formed between adjacent shrinking pieces 41. When the nut 5 is tightened, the shrinking pieces 41 shrink and then closely adhere to the guiding rod 3 to lock and fix the guiding rod 3.

[0025] Please refer to Figures 4-5 , in order to ensure the locking effect of the shrinking pieces 41, it is provided that the inside of the nut 5 is provided with a guiding body 51 that is thinner at the top and thicker at the bottom. When the nut 5 is tightened, the guiding body 51 gradually presses the shrinking pieces 41, so that the shrinking pieces 41 can shrink and closely adhere to the guiding rod 3. At the same time, a ring groove 31 is opened on the outer side wall of the guiding rod 3, and a matching protrusion 411 is provided at the position of the shrinking piece 41 corresponding to the ring groove 31. When the guiding rod 3 is inserted into the inside of the connecting cylinder 4, the protrusion 411 just snaps into the ring groove 31, thereby effectively preventing the problem of loosening of the guiding rod 3 and improving its connection firmness.

[0026] Please refer to Figures 3-4, an inclined connecting edge 11 is provided at the lower outer edge of the bin cover 1. The connecting edge 11 is integrally formed with the bin cover 1, and the upper outer edge of the bin body 2 adopts an inclined surface structure that matches the connecting edge 11. When the bin cover 1 and the bin body 2 are butted up and down, the connecting edge 11 is buckled on the inclined surface of the bin body 2, which is more convenient for butting and fastening compared with the traditional vertical connecting surface.

[0027] Furthermore, a sealing gasket 12 is inlaid on the inclined inner wall of the connecting edge 11, and the sealing gasket 12 is in close fit with the inclined surface of the bin body 2, so as to improve the sealing performance of the connecting edge.

[0028] Please refer to Figures 1-3 , a connecting groove 21 is provided on the bin body 2 corresponding to each connecting cylinder 4, and the nut 5 does not protrude from the connecting groove 21 when tightened, so as to facilitate the storage of the connecting cylinder 4 in the connecting groove 21 and prevent the connecting cylinder 4 from being collided during the use of the drone.
