Compulsive shaping device of bone joint

The invention discloses a compulsive shaping device of a bone joint. A lower part supporting bracket is connected with an upper part supporting bracket; a rotating chuck fixer is arranged at the joint of the upper part supporting bracket and the lower part supporting bracket, a gliding fixer is arranged on each of the upper part supporting bracket and the lower part supporting bracket, a lower semi-annular fixing frame is arranged on the gliding fixer, and an upper semi-annular fixing frame is arranged at the upper part of the lower semi-annular fixing frame; a fixing supporting disk is arranged on the lower semi-annular fixing frame, a moving fixing disk is arranged on the upper semi-annular fixing frame. Locking grooves for the rotating chuck fixer and the gliding fixer are locked by a special key, so as to prevent the compulsive shaping device of the bone joint from loosening for the mis-collision or artificially deliberate loosening. The compulsive shaping device of the bone joint is simple in structure and convenient to operate, and can lighten the labor intensity of medical workers, and effectively avoid operation failure and aggravation of patient's pain due to the deviation of operation position as the fixed and shaped gypsum is ruptured when it unexpectedly suffers from external force.
