The first positive electrode probe 14 is connected with the motor 11 through the coupling 13, the first negative electrode probe 16 is separated from the first positive electrode probe 14 by a first insulator 15 to prevent the positive and negative electrodes from being shorted, the first insulator 15 can be an insulating cylinder processed by materials such as PP (polypropylene), and the like, is sleeved between the positive and negative electrode probes and forms interference fit with the positive and negative electrode probes, so that the first positive electrode probe 14 and the first negative electrode probe 16 do not have relative motion.
