Abstract: The present invention relates to a milk frother assembly which makes the two stirrers rotate forward and reverse respectively, by using the reversing drive mechanism, rotating rod one, rotating rod two, a carabiner and two stirrers, so as to achieve the advantage of more efficient milk frothing and controlling of the quality of milk bubbles. The assembly allows through its novel setting of the length adjustment mechanism, to manually slide the slide plate, then move the rotating rod two through the sleeve and the connecting rod, and then adjust the position of the inner stirrer head, which is suitable for making milk froth in various capacities.
