Assembly type proximal femoral compression screw set

The embodiment of the utility model relates to an assembly type proximal femoral compression screw set. The assembly type proximal femoral compression screw set comprises a tool bit, a connecting component, a sleeve and an anti-rotation nut, the tool bit comprises a cutting part and a transmission part, and the outer wall of the transmission part is of a smooth structure; one end of the cutting part is connected with one end of the transmission part; the connecting part is of a hollow structure, and the outer wall of the connecting part is of a threaded structure. One end of the connecting part is connected with the other end of the transmission part; the other end of the transmission part and the connecting part are accommodated in the sleeve; when the connecting part rotates in the firstdirection under the action of first external force, the cutting part is driven by the transmission part of the tool bit to move in the direction close to the sleeve until the compression screw set reaches the locking state.
