The utility model discloses a theory of operation: through rotating the regulation pole in this scheme, make the electrode of both sides rotate in opposite directions, the electrode of both sides is close to gradually, reduces electric arc discharge air gap interval's length, otherwise the electrode of both sides is from rotating, increases electric arc discharge air gap interval's length. After the adjustment is completed, the limiting nut is screwed, and the purpose of fixing the adjusting rod is achieved by using the screwing force between the limiting nut and the outer side wall of the connecting pipe.

The utility model has the advantages that: through rotating the regulation pole, can freely adjust the length of electric arc discharge air gap interval according to the user demand to fix the regulation pole through the tightening force between stop nut and the connecting pipe surface.

Further, the connecting pipe is provided with a groove matched with the limiting nut in shape. Through setting up the recess, when stop nut screwed, area of contact between recess and the stop nut is big, and then the inside wall of recess can play spacing effect to stop nut, prevents that stop nut from loosening.

Further, the inner wall of the groove is provided with a rubber layer. The friction force on the surface of the rubber is large, and the tightening force between the limiting nut and the inner wall of the groove can be increased.

Furthermore, the limiting nuts are correspondingly arranged at two ends of the adjusting rod. Through screwing up the stop nut who adjusts the pole both ends, can play better limiting displacement to the regulation pole.

Furthermore, the limiting nut is a hexagon nut. The hexagonal nut has a plurality of edges and corners, and the edges and corners can make the limiting nut have force points when being screwed up, so that the limiting nut is convenient to screw up.

Further, the limiting nut is provided with a plurality of anti-skidding lines. The anti-skidding line can play skid-proof effect, is convenient for screw up limit nut.

Further, the side of the electrode away from the connecting pipe is bent into an arc-shaped part. The purpose that sets up like this can make the electric arc that forms between the electrode of both sides bleed air gap keep away from the insulator, guarantees the normal work of insulator.

Further, the hardware fitting is provided with an anti-rust layer. The antirust layer can play a role in preventing corrosion, and the service life of the hardware fitting is prolonged.
