Abstract
A femur rasp fastener has a frame and a linkage. The frame has a chamber for housing the linkage. When a femur rasp is engaged with the frame and a handle of the linkage is moved, an arched and elastic suspension bar will be driven to pull a bucking hear which is engaged with a front end of the suspension bar so that the bucking head will clamp a strut in an indented recess located at one end of the femur rasp. The femur rasp thus will be held securely and continuously by the frame of the fastener.
