Problems solved by technology

In this conductive structure, the electrode seat uses a spring 96 to press the electrode tile, and the pressure of the spring presses the electrode tile 93 to the electrode shaft. Due to the friction force generated between the electrode shaft and the electrode tile and the electrode seat during the rotation process, The pressing block 95 of the electrode seat pressing the motor tile is only connected by the spring 96 and the soft copper strip 98, and the pressin
