[0033] In this embodiment, the design of the assembly groove 15 facilitates the assembly of the partition 8. At the same time, the design of the assembly groove 15 also makes the position of the partition 8 more stable and less likely to move or fall off. Through the design of the second screw 16, the operator can easily screw the second screw 16 into the threaded hole of the isolation shell 1, thereby achieving a limiting effect on the shell cover 4.

[0034] In a further preferred embodiment of the present invention, a handle 17 for gripping is fixedly mounted on the bottom of the shell cover 4 , and a groove plate for limiting the position of the partition 8 is fixedly mounted on the bottom of the shell cover 4 .
