Transformer pre-tightening winding structure

The invention discloses a transformer pre-tightening winding structure. The transformer pre-tightening winding structure comprises a bottom plate; the left side of the top of the bottom plate is fixedly connected with a supporting rod; the top of the supporting rod is fixedly connected with a mounting plate; a supporting plate is fixedly mounted on the top of the left side of the supporting rod; the top of the supporting plate is fixedly connected with an electric telescopic rod; the right end of the electric telescopic rod runs through the supporting rod and is movably connected with a connecting rod through a pin shaft; the right end of the connecting rod is movably connected with a circular plate through a pin shaft; the bottom of the circular plate is fixedly connected with a rotary column I; and the bottom of the rotary column I is fixedly connected with a transformer body. By virtue of matching of the electric telescopic rod, the connecting rod, the circular plate, the rotary column I, the transformer b
