A kind of Nipple holder of this case system is by a substrate, a movable intermediate plate, and a moving plate and system tool are formed. When pulling the moving plate, during rotating the horn shape flange what of the moving plate, by wobbler action, the angle end of the horn shape flange or bevel is set selectively to push against or be bonded the oblique support arm of the activity intermediate plate, and the driven disc of the activity intermediate plate is formed to the movement for moving down or being upturned, so that the denture of the driven disc forms the clamping kenel being engaged with the tooth row of substrate or generates the pine clip-type state in gap. 本案係一種奶嘴夾，其係由一基板，一活動夾片，一扳動片，及一繫具所組成。當扳動該扳動片時，使該扳動片之角狀凸緣於轉動的過程中，藉由偏心作用，使該角狀凸緣之角端部或斜削面選擇性地抵緊或貼合該活動夾片之斜向支臂，而將該活動夾片之從動片形成向下移動或向上翹起的運動，使得該從動片的齒列與基板的齒排形成咬合之夾合型態或產生間隙之鬆夾型態。
