The invention relates to the technical field of steel wire processing, in particular to a special rotary connector for stainless steel wire smashing. The invention adopts the technical scheme that thespecial rotary connector for stainless steel wire smashing comprises a cylindrical body assembling connecting plate, wherein a cylindrical center assembling positioning connecting groove is formed inthe center of the upper end of the body assembling connecting plate; a cylindrical stable assembling connecting column is arranged in the center of the inner part of the center assembling positioningconnecting groove; an integrally formed inverted cone-shaped first rotary acceleration connecting column is arranged in the center of the lower end of the body assembling connecting plate; an integrally formed cylindrical reinforced connecting support column is arranged at the lower end of the first rotary acceleration connecting column; and an integrally formed inverted cone-shaped second rotaryacceleration connecting column is arranged at the lower end of the reinforced connecting support column. The special rotary connector for stainless steel wire smashing provided by the invention has the advantages that during the moving process, a smashing effect is better, so that the overall efficiency during the smashing process can be improved, and the homogeneity in smashing can be ensured.
