Claim:
1. A transformer structure, comprising: a winding cylinder which is a hollow tube; at least one limiting ring, which is a ring sheet and able to slide along the winding cylinder and to sleeve on the outside of the winding cylinder; a plurality of conductive sheets sleeved on the outside of the winding cylinder, wherein two of the conductive sheets adjacent to each other are attached to two end surfaces of the at least one limiting ring sandwiched therebetween respectively while the two of the conductive sheets and an outer surface of the at least one limiting ring sandwiched therebetween form a winding space; and at least one winding correspondingly disposed in the winding space and being directly in contact with the two of the conductive sheets and the outer surface of the at least one limiting ring sandwiched therebetween.
