ABSTRACT:
An improved adjustable device for artificial limbs includes: a cylindrical member having an open section at an upper end for being fixedly coupled with a lower stump portion of an artificial limb, and an annular recess with a plurality of cavities and through openings formed at a lower end; and a coupling member with a mounting piece for being connected to an upper joint portion of an artificial limb and a circular convex protrusion provided on top of the mounting piece with a plurality of screw holes formed in the circular convex protrusion for being coupled with the cylindrical member through a plurality of screw bolts; so that, by adjusting the screw bolts adjustably fixed in the through openings of the cylindrical member, the gravitational equilibrium of the adjustable device can be easily obtained without taking apart the artificial limb incorporated therewith.
