Stereoscopic iron core transformer convenient to maintain

The invention discloses a three-dimensional iron core transformer convenient to maintain, and relates to the technical field of three-dimensional iron core transformers, the three-dimensional iron core transformer convenient to maintain comprises a box body, first fixing blocks, fixing assemblies, a cover plate and round blocks, the first fixing blocks are fixedly connected to the left side and the right side of the box body, and the fixing assemblies are arranged at the ends, away from the box body, of the first fixing blocks; by means of the fixing assembly, when the stress plate makes contact with the outer surface of the telegraph pole, extrusion force from the telegraph pole can be borne, then the T-shaped block is driven to move towards the interior of the sliding groove and extrudes the elastic plate, when the elastic plate is stressed, outward extrusion force can be generated, and then the connectivity between the stress plate and the telegraph pole can be improved; by means of the triangular plate, s
