The utility model acupuncture needle,It is mainly formed with first on what needle body,Second positioning area,And this etc. each positioning fauna be needle body circle around forming,The maximum outside diameter big what of each positioning area institute corral needle body outer diameter simultaneously,Cooperate the perforation in lever to be formed with one again at this time and limit region (i.e. second area),When wearing the lever so as to the needle body,It is stretchable using second positioning area and generate the characteristic of telescopic variation,Promote this first,Second positioning area can clip positioning what this limit region two sides (i.e. first,Third region),And then reach the needle body strong fix effect,Effectively exempt because the run-bake-needle fault facts for the improper generation that exerts a force occurs,Greatly promote the safety used and convenience.本新型針灸針，其主要在於針體上形成有第一、第二定位區，且該等每一定位區係為針體圈繞而成，同時該每一定位區所圈圍之最大外徑大於該針體外徑，此時再配合握柄內之穿孔形成有一限縮區域(即第二區域)，以便該針體穿設該握柄時，可利用該第二定位區可拉伸而產生伸縮變化之特性，促使該第一、第二定位區可卡掣定位於該限縮區域的二側(即第一、第三區域)，進而達到該針體穩固定位效果，有效免除因施力不當產生之脫針情事發生，大大提升使用之安全性與便利性。
