[0002] At present, transformer coil winding dies are generally fixed coils wound on insulating cylinders, and the insulating cylinders are sleeved on the molds. The coil wire molds of the transformers have relative sizes according to the size of the molds and cannot be extended or retracted. There are also adjustable molds on the market, but the structure is relatively complex and the cost is relatively high, which is not conducive to widespread promotion and use. Therefore, there is a need for an adjustable and easy-to-use transformer coil winding mold to save costs and be environmentally friendly. In addition, the support bars on the winding mold cannot be adjusted separately, and cannot meet the user's needs for the diameter of the umbrella tire when fixing copper plates of different specifications on the support bars.
