Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments. Example

[0021] like Figures 1-4As shown, a grounding negative electrode device includes an "L"-shaped mounting bracket 1 and a copper rod 5. The "L"-shaped mounting bracket 1 includes a mounting surface 11 and a supporting surface 12. Two mounting holes 2 are provided on the supporting surface 12, both being oblong holes for easy adjustment of the mounting position during installation. A nylon protective block 3 is mounted on the mounting surface 11 by screws. The nylon protective block 3 serves as insulation, preventing current from flowing through the mounting bracket 1 to other equipment and personnel. A first through hole 111 is provided on the mounting surface 11. The nylon protective block 3 is boss-shaped, with a stepped hole and a second through hole 4 in the middle. The second through hole 4 penetrates the nylon protective block 3 and is connected to the stepped hole. The copper rod 5 is "T"-shaped, with its lower end passing through the second through hole 4. The outer diameter of the second through hole 4 is smaller than the outer diameter of the first through hole 111. The lower section is equipped with a retaining spring 6, which is located below the lower end face of the nylon protective block 3. The outer diameter of the retaining spring 6 is larger than the inner diameter of the second through hole 4, serving as a limit. It also includes a bushing 7, which is T-shaped and fits onto the copper rod 5. The stepped hole is divided into an upper hole and a lower hole. The outer diameter of the upper end of the bushing 7 is larger than the inner diameter of the lower hole. A spring 8 is provided between the upper end face of the upper end of the bushing 7 and the lower end face of the upper end of the copper rod 5. The bushing 7 moves up and down in the upper hole as the copper rod 5 moves, so that it can better contact the plate and avoid the problem of hitting the plate during installation. The bushing 7 can effectively reduce the wear caused by the up and down floating of the copper rod 5, effectively extending the service life of the equipment. The lower end of the copper rod 5 passes through the nylon protective block 3 and the first through hole 111 and is equipped with a grounding wire mounting bolt 9. The grounding wire mounting bolt 9 installs the grounding wire at the lower end of the copper rod 5.

[0022] During use, the copper rod 5 contacts the workpiece, and the grounding wire between the copper rod 5 and the grounding wire mounting bolt 9 forms a closed loop with the earth, providing a stable reference potential and diverting excess current to the earth, protecting personnel and equipment safety. During installation, the spring prevents the top plate from forming.
