The invention provides a multiple-sheet combined artificial joint cup structure which comprises a plurality of cup structure sheets and a plurality of structure sheet fixing pawls. The structure sheetfixing pawls are arranged on the external structure surface of each cup structure plate and are used for fixing the cup structure plate to the connection part of adjacent bones. According to the structure of the invention, the artificial joint cup structure can be divided into a plurality of sheets according to the number and angle of the adjacent bones and the distance of adjacent bones as a reference thickness； and furthermore fine adjustment is performed on the combined cup structure surface through an adjustment clearance between the cup structure plates, thereby improving engagement degree between the artificial joint cup structure and adjacent bones and reducing wearing to an artificial joint sphere structure.本發明提供一種多片組合式人工關節臼杯結構，其結構包含：多個臼杯結構片以及多個結構片固定爪，該些結構片固定爪係設置於各該臼杯結構片之外結構面，用以將各該臼杯結構片固定於各該相鄰骨骼之銜接處。本發明可將臼杯結構依照相鄰骨骼的數量與角度，以與相鄰骨骼的距離為參考厚度分成數片，並且透過臼杯結構片與臼杯結構片中留有的調整間隙對組合後的臼杯結構面進行微調，以增加人工關節臼杯結構與相鄰骨骼的銜接度並減少與人工關節球體結構之磨耗。
