The invention relates to a structure of a sharpening device, which mainly comprises a cup body, a convex grinding base and a spring, wherein the outer edge of the bottom of the cup body is expanded with an upward groove, and the recess of the cup body can be convex The abrasion rod of the type abrasion holder is accommodated and extended, and the top plate of the convex abrasion holder is fixed with a spring on the periphery of the abrasion rod, so that the abrasion rod can be accommodated and extended. When the cup is recessed, the other end of the spring abuts the inside of the ring groove and keeps the end of the abrasion rod suspended above the bottom of the recess, forming an operation that can press the abrasion rod to hit the cup and reset by the spring. The medicine tablets can be quickly pounded and ground into powder after being placed in the cup.本發明係一種磨藥器結構，主要包括有杯體、凸型磨藥座及彈簧所組成，其中杯體的底部外緣擴設有朝上的環槽，該杯體的凹口可供凸型磨藥座凸伸的磨藥桿容置、伸入，且凸型磨藥座外擴的頂盤是固設有彈簧於磨藥桿的外圍，俾可令磨藥桿容置、伸入杯體的凹口時，彈簧的另端抵於環槽內部並保持磨藥桿端部懸空於凹口底部上方，形成一可施壓磨藥桿搗擊杯體並由彈簧復位的操作，以利藥錠置入杯體後可以快速搗、磨成藥粉者。
