A height-adjusting medical crutch, whose conventional one is made to be fixed in a two-dot method, in which a screw bolt and a nut are used on the parts which confront a middle bottom frame 100 and a side frame 102 by using an aluminum tube, wherein its improvement comprise a fixed globe 6, wherein its center is penetrated so that a middle bottom frame 4 may go in and out, a side frame 8, a rivet 10, by which the fixed globe 6 is fixed on lower part of the side frame 8 and a middle bottom frame 4, which is moved through the inner side of the fixed globe 6, so that the height of the medical-adjusting medical crutch may be easily adjusted. And, in this invention, a tight coupler 12 having an arc form is formed continuously on the inner radial surface of said fixed globe 6 and said tight coupler 12 adheres to space between the middle bottom frame 4 and the side frame 8 and a side frame 8a is penetrated to be inserted into both sides of the inner radial surface of the fixed globe 6a and the side frame 8a is fixed on the upper edge and lower edge of the medical crutch.
