[0030] like Figure 2 As shown, the side assembly shell 1 consists of two parts: a bottom shell 101 and a side shell 102. The side shell 102 is integrally formed on one side of the bottom shell 101, and several threaded connecting seats 3 are fixedly connected to the inner wall of the side shell 102.

[0031] Specifically, a sealing groove is provided on the side of the bottom shell 101 that is close to the upper assembly shell 2. The sealing groove provides an assembly clearance cavity for the sealing positioning block 8.

[0032] like Figures 2 to 6 As shown, a sealing gasket 7 is attached to the inner wall of the sealing groove. The sealing gasket 7 improves the sealing performance of the sealing positioning block 8 and the sealing groove.

[0033] like Figures 3 to 4 As shown, a sealing positioning block 8 is integrally formed on the side of the upper assembly shell 2 closest to the bottom shell 101.
