Knee joint buckling angle retention support for nuclear magnetic imaging experiment

The invention discloses a knee joint buckling angle retention support for a nuclear magnetic imaging experiment. The knee joint buckling angle retention support comprises a lying plate; the supporting device is rotationally connected to the middle of the top of the lying plate and comprises a first supporting plate, one side of the first supporting plate is rotationally connected with a second supporting plate, a fixing block is fixedly installed on the other side of the second supporting plate, a threaded hole is formed in one side of the fixing block, and a base plate is fixedly installed on one side of the outer surface of the second supporting plate. According to the knee joint buckling angle retention supporting device for the nuclear magnetic imaging experiment, a rotating block is rotated to drive a lead screw to rotate to be meshed with a threaded hole of a fixing block to drive a second supporting plate to move in a sliding groove, the supporting position is adjusted, and the knee joint buckling angl
