The lower end of the rotating rod 8 rotatably extends out of the lower sides of the insertion rod 4 and the electrode 5. The cleaning block 9 is slidably connected to the outer surface of the electrode 5. The shape of the cleaning block 9 is L-shaped. The cleaning block 9 can contact the lower side of the outer surface of the electrode 5. The cleaning block 9 is fixedly connected to the outer surface of the electrode 5. The first bevel gear 10 is fixedly sleeved on the outer surface of the rotating rod 8. The first bevel gear 10 is arranged inside the meshing groove 7. The fixing block 11 is fixedly connected to the right side of the insertion rod 4. The motor assembly 12 is fixedly connected to the right side of the fixing block 11.

[0034] Working principle: When starting to work and when it is necessary to clean the dirt on the outer surface of the electrode 5, the motor assembly 12 is started. The motor assembly 12 transmits power from the output end, driving the transmission shaft 13 to start rotating. The transmission shaft 13 drives the second bevel gear 16 to rotate synchronously. The second bevel gear 16 drives the engaged first bevel gear 10 to rotate. The first bevel gear 10 drives the rotating rod 8 to rotate synchronously. The rotating rod 8 drives the cleaning block 9 to rotate synchronously. Thus, during the rotation process, the cleaning block 9 scrapes the outer surface and the lower side of the electrode 5, and the dirt attached to the electrode 5 will be cleaned off. During the working process, the limiting ring 15 is limited inside the limiting groove 14, thus ensuring the stability of the transmission shaft 13 and the stability of the meshing between the second bevel gear 16 and the first bevel gear 10. At the same time, the limiting slider 18 is limited inside the limiting ring groove 17 to rotate, and the limiting slider 18 limits and fixes the cleaning block 9, thus ensuring the tightness of the contact between the cleaning block 9 and the electrode 5 and ensuring the cleaning quality of the electrode 5.
