This creation system provides a kind of crutch orientation stretching structure, mainly in what inner and outer pipe with the noose end of a wherein tube body towards being recessed with certain position protrusion in pipe, and another tube body is then towards an axial channel recessed in pipe, in order to inner and outer pipe mutually set group when, tool orientation guiding structure is formed by being oppositely arranged axial caulking groove and positioning convex portion, and then more stable, smooth and more convenient property in telescopic adjustment operation is provided and is used.本創作係提供一種拐杖定向伸縮結構，主要在於內、外管以其中一管體之套結端朝管內凹設有一定位凸部，而另一管體則朝管內凹設一軸向導槽，俾內、外管相互套組時，藉由相對設置軸向嵌槽及定位凸部形成具定向導引結構，進而提供伸縮調節操作上更具穩定、順暢及更便利性使用。
