Split type hinge connecting shaft structure

The utility model relates to a split type hinge connecting shaft structure which comprises a connecting shaft and a shaft base with a T-shaped cross section, the shaft base comprises a shaft sleeve and a hollow shaft which are perpendicular to each other, the shaft sleeve and the hollow shaft are of a split type structure, and a hole for the hollow shaft to penetrate through is formed in the center of the shaft sleeve. The shaft sleeve is used for allowing the connecting shaft to penetrate through, the top, connected with the femoral condyle prosthesis, of the shaft sleeve is in threaded connection with an end cover, a hole matched with a bolt is formed in the center of the end cover, and the bolt is connected with the femoral condyle prosthesis and the end cover; the connecting shaft is limited by arranging the hollow shaft perpendicular to the connecting shaft, so that displacement between the connecting shaft and the shaft sleeve caused by axial stress during knee joint movement is prevented, and the stabi
