Abstract: A connection pair of threads outlining an asymmetrically and bidirectionally tapered dumbbell shape having a smaller left-end conical degree. The present invention relates to the common technical field and solves the problems of poor self-positioning and self-locking of existing threads, etc. An internal thread (6) on the inner surface of a cylindrical body (2) outlines a bidirectionally tapered hole (41) and is present in form of a non-entity space. An external thread (9) on the outer surface of a columnar body (3) outlines a bidirectionally tapered-frustum body (71) and is present in form of a material entity, and each complete threaded body unit forms a special bidirectionally tapered body in a helical dumbbell shape (94) having a small middle part and two large ends, the left-end conical degree (95) being smaller than the right-end conical degree (96). The performance mainly depends on the tapered face and the conical degrees of the fitted threaded body, and the advantage is that the internal thread and the external thread outline the tapered body by means of the tapered hole, such that the bidirectionally tapered hole (41) and the bidirectionally tapered-frustum body (71) form a thread pair (10) with joints of tapered pairs until the inner and outer tapered bodies have helical tapered faces with sizing fit or sizing interference, so as to realize the threaded connection function.
