The first positioning frames 22 are evenly distributed on the outer peripheral wall of the connecting housing 21. The second positioning frames 3 are installed on the side of the mounting housing unit 2 away from the housing body 1. The outer peripheral wall of the second positioning frames 3 is evenly distributed with fixing blocks 31, which are corresponding to the first positioning frames 22.

[0024] like Figure 1 and Figure 3 As shown, the first positioning frame 22 cooperates with the main housing 11 to define the cover body 1 and the mounting housing unit 2; the fixing block 31 cooperates with the first positioning frame 22 to fix the mounting housing unit 2 and the second positioning frame 3.

[0025] like Figure 3 As shown, the main housing 11, connecting housing 21 and fixing block 31 cooperate to form a high-strength connection end, preventing misalignment or skew during assembly and use, and at the same time improving the overall connection strength of the cover body 1, the mounting housing unit 2 and the second positioning frame 3.

[0026] According to the appendix Figure 2 and Figure 4As shown, the main housing 11 has a first stepped groove 111, a second stepped groove 112 and a third stepped groove 113, which are distributed in a stepped manner.

[0027] The first positioning frame 22 has a fifth step groove 222 and a fourth step groove 221, which are distributed in a stepped manner.

[0028] The fifth step groove 222 and the fourth step groove 221 are respectively attached to the second step groove 112 and the third step groove 113 to form a high-strength connection end to prevent misalignment and skewing.
