It is worth noting that the specific structure of the nut 131 is not further limited in this embodiment. As long as the first fastening assembly 13 is preset in the placement cavity 110, the first fastening assembly 13 can play a fastening role, which is within the protection scope of this application. The diameter of the first opening 120 is larger than the diameter of the placement cavity 110, and the first washer 1321 is arranged in the first opening 120, and the first washer 1321 abuts against the top of the first frame 3. In a modified embodiment, the first washer 1321 can also be arranged between the bottom wall of the shell 1 and the first frame 3 and is located outside the first opening 120.

[0063] Furthermore, after being assembled, the nut 131 , the first washer 1321 and the second washer 1322 are placed in the placement cavity 110 through the first opening 120 . The first opening 120 is larger than the first fixing hole 31 , so that the nut 131 is suitable for locking the first frame 3 .

[0064] It is worth noting that in the present application, the first opening 120 of the shell 1 is greater than or equal to the outer size of the first fastening component 13, and the first fastening component 13 is placed in the placement cavity 110 through the first opening 120. In order to better and more conveniently place the first fastening component 13, the first components can be glued together using a screw glue or other adhesive structure, so that the first fastening component 13 can be placed in the placement cavity 110 as a whole. In a modified embodiment, the first opening 120 of the shell 1 can also be smaller than the size of the first fastening component 13 and suitable for the second fastening component 2 to pass through. The first fastening component 13 is first preset inside the shell 1 during molding. After the shell 1 is molded, the first fastening component 13 is preset and fixed inside the shell 1. It is sufficient to leave the first opening 120 for the second fastening component 2 to pass through the bottom of the shell 1, and the first opening 120 is smaller than the first fastening component 13.

[0065] Furthermore, it also includes a second fastening component 2, which is suitable for connecting to the first fastening component 13 through the second fixing hole 41, the first fixing hole 31 and the first opening 120, so that the first frame 3 and the connecting structure 4 are fixedly connected.

[0066] Specifically, refer to Figure 8, and also includes a second fastening component 2, the second fastening component 2 includes a bolt 21, and the bolt 21 passes through the first fixing hole 31 and the first opening 120 and then connects to the first fastening component 13. It is worth noting that the second fastening component 2 includes but is not limited to the bolt 21, and can also be other fasteners such as screws. This is easy for a person skilled in the art to think of, and this application will not be further elaborated. At the same time, a fourth washer can also be sleeved on the second fastening component 2 to increase the contact area between the second fastening component 2 and the connecting structure 4, evenly distribute the pressure, and protect the surface of the connecting structure 4; or increase the locking force to prevent the second fastening component 2 from loosening, etc.

[0067] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
