Abstract
A height-adjusting medical crutch having a fixed globe (6) whose center is penetrated so that a middle bottom frame (4) can pass therethrough, a side frame (8), a rivet (10) which fixes a fixed globe (6) on a lower part of the side frame (8) and the middle bottom frame (4) which is moved through the inner side of the fixed globe (6) so that the height of the medical-adjusting crutch can be adjusted. A tight coupler (12) having an arc form is formed continuously on the inner radial surface,of the fixed globe (6) so that the tight coupler (12) adheres to the space between the middle bottom frame (4) and the side frame (8). 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.
