基于自紧力理论，V口自紧扳手大胆地突破改变了传统活扳手活动扳唇和呆扳唇之间的 平行，创造性地在扳唇上开了V口，并且安装了灵活的活动齿块。通过这一对结构的根本 性的创新改变，使得V口扳手具备了全新的强大的功能。
Based on our theory of self-tightness, V shape Jaw Self-adjustable Wrench broke through the parallel betweenthe moveable jaw and the fixed jaw of traditional adjustable wrenches, and creatively installed moveable teeth onthe fixed jaw that made the two jaws take a shape of “V”. This structural innovation enables the V shape wrenchto realize more brand-new powerful functions.
