An interdental cleaning device is adapted for use with a dental floss roll (2) and includes a main body (3) and a floss holder (4). The main body (3) defines a receiving space (36) configured to receive the dental floss roll (2). The floss holder (4) is pivotally connected to the main body (3) and defines a guiding channel (45) in spatial communication with the receiving space (36). The floss holder (4) has a securing end (56), and an open end (421) that is spaced apart from the securing end (56) and that is formed with an opening to spatially communicate the guiding channel (45) with external environment. A to-be-used segment (21) of the dental floss roll (2) is extendible through the opening of the open end (421) via the guiding channel (45) so as to be secured at the securing end (56) of the floss holder (4).一種潔牙裝置,供一成捲的牙線設置,並包含一本體及一牙線架。本體包括一樞接部,且本體界定一容置空間;牙線架可相對旋轉的連接本體,並包括一相對樞接部樞轉的勾部,牙線架界定一連通容置空間的導引通道並具有一固定端,及一與固定端相間隔的開口端,牙線藉由一端延伸通過導引通道並伸出開口而固定於固定端,而一局部段外露於開口端與固定端之間。藉扳動牙線架的勾部,使勾部能相對於本體的樞接部樞轉,且不易鬆脫,直到下次受到外力扳動勾部時,才會再次改變傾角。不僅操作簡易且能有效地深入牙縫死角,進而輕鬆托出殘留異物。2‧‧‧牙線3‧‧‧本體31‧‧‧握柄32‧‧‧延伸部33‧‧‧樞接部34‧‧‧殼座35‧‧‧殼蓋351‧‧‧容置槽36‧‧‧容置空間37‧‧‧第二開口38‧‧‧切斷部4‧‧‧牙線架41‧‧‧軸部42‧‧‧勾部421‧‧‧開口端43‧‧‧第一架體44‧‧‧第二架體45‧‧‧導引通道5‧‧‧調整單元51‧‧‧調整螺絲52‧‧‧調整罩56‧‧‧固定端6‧‧‧第一開口A‧‧‧軸心方向L‧‧‧長度方向
