A kind of clamp holder device with positioning action of what is closed in this creation comprising first and second shank body and a pivot. One end of first shank body is equipped with first and second engaging lug separated, and one end of second shank body is equipped with first and second lug separated. It is equipped with a non-circular perforation individually on an engaging lug and a wherein lug wherein. The pivot passes through the engaging lug of first shank body and the lug of second shank body, first and second shank body is articulated. The centre of the pivot has a positioning region, which has non-circular section and the corresponding non-circular perforation across first and second shank body. The pivot can move between a first position and a second position, and when the pivot is at the first position, which cannot be pivoted relative to each other, and when the pivot is at the second position, which opposite can be pivoted. The clamp holder device is suitable for constituting the main component of deseeding device, ice cream spoon or fixture.本創作關於一種具有定位作用的夾柄裝置，其包括第一與第二柄體及一樞軸。該第一柄體的一端設有分隔的第一與第二連接耳，該第二柄體的一端設有分隔的第一與第二凸耳。在其中一連接耳與其中一凸耳上個別設有一非圓形穿孔。該樞軸穿過該第一柄體的連接耳與該第二柄體的凸耳，將第一與第二柄體樞接在一起。該樞軸的中間具有一定位部，該定位部具有非圓形的斷面且對應穿過該第一與第二柄體的非圓形穿孔。該樞軸可在一第一位置與一第二位置之間移動，當該樞軸在該第一位置時，該第一與第二柄體不能相對樞轉，且當該樞軸在該第二位置時，該第一與第二柄體可相對作樞轉。該夾柄裝置適用於構成去籽器、冰淇淋杓或夾具的主體構件。
