Polishing mechanism for power supply facility

The invention belongs to the technical field of power supply facility production, and particularly discloses a polishing mechanism for a power supply facility, which comprises a third sleeve coupling and a fourth sleeve coupling, the third sleeve coupling and the fourth sleeve coupling have the same structure, and the third sleeve coupling is rotatably connected with the fourth sleeve coupling through a second hinge. Polishing pieces are fixedly connected to the inner wall of the third sleeve coupling and the inner wall of the fourth sleeve coupling, fixing structures are distributed on one side of the third sleeve coupling and one side of the fourth sleeve coupling, and telescopic structures are distributed between the fixing structures and the third sleeve coupling. When the mechanism is actually used, the side wall of the cement electric pole can be rapidly polished, the cement electric pole can be conveniently transported by a worker in the follow-up process, the mechanism can be rapidly installed on the
