[0030] Specifically, two inclined support brackets 2 are welded to the lower surface of the grounding copper busbar 1. Rubber pads 19 are provided at the bottom of the inclined support brackets 2. The bottom of the inclined support brackets 2 and the rubber pads 19 are fixedly connected to the inner bottom surface of the electrical cabinet 20 via screws. Advantageously, by providing the inclined support brackets 2 to connect the grounding copper busbar 1, the grounding copper busbar 1 can be securely fixed by screwing the bottom of the inclined support brackets 2 and the rubber pads 19 to the inner bottom surface of the electrical cabinet 20. Furthermore, the inclined support brackets 2 are arranged in an inclined position, making it easier to screw the screws from top to bottom without being blocked by the grounding copper busbar 1. Furthermore, the provided rubber pads 19 are insulating, preventing electricity from being conducted to the outer casing of the electrical cabinet 20.
[0031] Specifically, a rectangular hole is provided on one side of the electrical cabinet 20 for the Z-shaped connector 7 to pass through.

In this way, the top ends of the two support plates 13 can be embedded in the ground from the side of the fixing nail 12, thereby enhancing the grip of the fixing nail 12 and further improving the firmness of the grounding electrode 11, preventing it from being easily pulled out.
[0035] When in use, first fix the bottom of the inclined support seat 2 together with the rubber pad 19 to the inner bottom surface of the electrical cabinet 20, then connect the ground wires of each electrical component in the electrical cabinet 20 to the copper nose 4, then put the copper nose 4 on the copper joint 3, and fix the copper nose 4 to the grounding copper bus 1 by tightening the nut 5, then pass one end of the Z-shaped connector 7 through the rectangular through hole on the outside of the electrical cabinet 20, and at the same time install insulating rubber pads 21 on the outside and inside of the electrical cabinet 20, then connect the Z-shaped connector 7 to the grounding copper bus 1 with bolts, then connect the copper sheet 8 to one end of the Z-shaped connector 7, then insert the grounding electrode 11 and the fixing nail 12 into the ground at the same time, and then by rotating the adjusting rod 18, the sleeve 17 can move downward on its outer surface, so that the ear block 2 16 can be driven, the ear block 2 16 drives the connecting rod 15, and the connecting rod 15 drives the support plate 13 to expand outward, so that the top ends of the two support plates 13 can be embedded in the ground from the side direction of the fixing nail 12, thus completing the grounding operation.
