The coils are respectively led out with inner lead copper bars and outer lead copper bars, and the upper support assembly and the inner lead copper bar are connected by an insulator. It is characterized in that the upper support assembly includes an upper support, an upper mounting plate, and an adjustable pad placed between the upper support and the upper mounting plate. Although this patent solves the problem of loose connection between the upper support assembly and the lead copper bar, the upper support, the adjustable pad and the upper mounting plate are all connected by multiple bolts. In actual use, it is found that the installation is very cumbersome, and the bolts are very easy to rust after being used for a long time, making it impossible to maintain and adjust. Therefore, it is necessary to further optimize and improve the structure. Utility Model Content
