[0025] The fixing block 4 is moved by rotating the fixing handle 11, and the module pole core 2 is fixed by driving the fixing block 4 through the screw 3 to ensure the stability of the module pole core 2. During the subsequent disassembly, assembly and maintenance of the grounding module 1, it is convenient to replace it through the screw 3 and the fixing block 4.

[0026] The grounding mechanism includes a pole 5, a nut 6 and an expansion tube 7. The pole 5 is connected to the grounding module 1.
