The invention relates to a betel nut rolling machine clamping structure, which comprises a machine base disposed therein at least a transmission device, a rotational pushing and abutting device, a clamping device and a knife displacement device and a filling seat penetratingly disposed at the side of the machine base, wherein the filling seat is adjacent to the clamping device and the knife displacement device. With the aforementioned structure, after a betel nut is filled in the filling seat, the clamping device clamps the betel nut to stably fix it. The transmission device rotationally drives the rotational pushing and abutting device and the clamping device to rotate. The clamping device rotates while the knife displacement device scratches the surface of the betel nut. Finally, the betel nut is pushed out by the rotational pushing and abutting device, so as to achieve the efficacy of enhancing the mouthfeel when chewing the betel nut with cut surface.一種檳榔滾錢機夾持結構,至少包括:一機座,內部係至少設置一傳動裝置、一旋動推抵裝置、一夾持裝置及一刀具位移裝置而成,且該機座側面穿設一填塞座,該填塞座鄰近該夾持裝置及該刀具位移裝置;藉由上述結構,將檳榔填塞至該填塞座後,該夾持裝置夾持檳榔使其穩固,該傳動裝置旋轉帶動該旋動推抵裝置及該夾持裝置旋轉,該夾持裝置旋轉同時該刀具位移裝置將檳榔之表面劃刀痕,最後再由旋動推抵裝置將檳榔推出,達到表面切割後之檳榔咀嚼時增加口感之功效。12‧‧‧填塞座20‧‧‧傳動裝置24‧‧‧第一動力源281‧‧‧第一齒輪282‧‧‧第二齒輪283‧‧‧傳動件30‧‧‧旋動推抵裝置31‧‧‧推動結構32‧‧‧第一套筒362‧‧‧推抵板40‧‧‧夾持裝置42‧‧‧底座44‧‧‧夾爪50‧‧‧刀具位移裝置57‧‧‧升降座
