At this time, the spring 11 is forced to stretch. When the positioning column 13 moves downward to the position where the insertion hole 14 is aligned with the insertion rod 9, the elastic force of the spring 11 is used to force the insertion rod 9 to be inserted into the inner cavity of the insertion hole 14 at the corresponding position, so as to realize the positioning of the insertion hole 14 after being inserted into the inner cavity of the first positioning ring 8, that is, to realize the docking connection between the second positioning ring 12 and the first positioning ring 8, that is, to realize the rapid positioning of the aerator 4 above the branch pipe 3.
