ABSTRACT:
A ceramic valve core has a multi-stage positioning structure. The multi-stage positioning structure includes a first snapper, which can move along with the swaying motion of the brake valve handle of the ceramic valve core, and a second snapper, which is an integrated component positioned correspondingly to the displacement track of the said first snapper. At the corresponding ends of the first snapper and the second snapper, there is a snap ring mated with at least two pin joint ends. The positioning structure also includes a flexible member, which allows the first snapper or second snapper to operate flexibly. The multi-stage positioning structure of the present invention is sturdy because the first snapper is of a combined type and is flexible thanks to the flexible member.
