    • The attachment system includes a brushhead assembly having a spring/carrier combination which comprises a spring assembly and a separate carrier assembly, adapted to mate as a combination with a receiving portion, in the form of a cup member, at the top of the handle of the toothbrush. The spring/carrier combination includes a slot which mates snugly with a vertical rib on the inside surface of the cup member, and further includes a portion which opposes the slot on the spring/carrier combination which mates snugly with a cut-out portion in the cup member, to prevent rotational movement of the brushhead relative to the handle. The spring/carrier assembly further includes two opposing spring finger elements which extend downwardly from an upper edge of the spring/carrier assembly and are joined thereto such that the lower ends of the spring fingers have a slightly outward springing action, wherein the lower ends of the spring fingers fit into corresponding openings in opposing sides of the cup member when the spring/carrier assembly is operatively positioned in the cup member, tending to prevent translational movement of the brushhead relative to the handle.
    • 附接系统包括具有弹簧/托架组合的刷头组件,其包括弹簧组件和单独的托架组件,该组件适于与杯构件的形式的接收部分组合地配合在手柄的顶部 牙刷 弹簧/载体组合包括与杯构件的内表面上的垂直肋配合配合的狭槽,并且还包括与弹簧/载体组合上的狭槽相对的部分,其与所述弹性/载体组合中的切口部分配合 杯部件,以防止刷头相对于把手的旋转运动。 弹簧/托架组件还包括从弹簧/托架组件的上边缘向下延伸的两个相对的弹簧指元件,并且连接到弹簧/托架组件上,使得弹簧夹的下端具有略微向外的弹性作用,其中, 当弹簧/支架组件可操作地定位在杯构件中时,弹簧指状物装配到杯构件的相对侧中的对应开口中,倾向于防止刷头相对于手柄的平移运动。
