[0023] like Figure 3 and Figure 4 As shown, the casing body 1 is bent around the cylinder to form a casing ring shell, and multiple first protrusions 2 are respectively engaged with multiple first arc-shaped grooves 3 to be clamped together. At the same time, multiple second protrusions 6 are respectively engaged with multiple second arc-shaped grooves 7 to be clamped together. Welding is performed at the joints between the multiple first protrusions 2 and the multiple first arc-shaped grooves 3 and the joints between the multiple second protrusions 6 and the multiple second arc-shaped grooves 7 to form welds 9. Welding points 10 are formed at the upper and lower ends of the weld 9 of the casing ring shell, further strengthening the strength of the casing body 1 after bending and forming, ensuring that the weld 9 will not crack after long-term use of the casing body 1, and improving the strength of the casing body 1. On the casing ring shell formed by the casing body 1, the first slot 4 and the second slot 8 are opposite, and the corresponding motor accessories are installed in the casing body 1, and are engaged with the external structure through the slot 5.
