The invention provides an artificial hip joint prosthesis which is flexible in adjustment, capable of meeting movement requirements in each direction and high in wear resistance of related contact surfaces to solve technical problems. An implanting tool is improved to reduce operation wounds. The artificial hip joint prosthesis comprises a femoral stem, a femoral bulb and an elastic connector. A far end of the femoral stem can be inserted in a femoral marrow cavity, a near end of the femoral stem extends upwards laterally, an included angle between the axis of an extending end and the axis of the femoral stem under a natural state is 110-140 degrees, the end of the extending end is suddenly thinned into a step shape, a thin section extends upwards laterally by 6-10mm and is used for fixing the elastic connector, one end of the elastic connector is inserted into the thin section and abutted against the step position while the other end of the elastic connector is connected with the femoral bulb, and the joint of the femoral bulb and the elastic connector is provided with a column projection 6-10mm in length. Therefore, arbitrary adjustment of the artificial hip joint prosthesis in each angle is realized, and especially adjustment of a front inclination angle and a collodiaphyseal angle at a sagittal view and a coronal view is realized.
