The invention discloses a double-end pull rod type connecting pair and a mounting method. The connecting pair is composed of a double-end pull rod of a steel rod structure, a lantern ring used for extrusion riveting and a sleeve nut used for threaded connection. A threaded section, a first transition section, an embedded friction section, a second transition section, an annular groove section, a positioning table and a tail tooth are sequentially arranged on the double-end pull rod cylindrical steel rod from one end to the other end. The thread section is provided with a thread with a spiral structure; protrusions used for increasing friction of the rod surface are arranged on the surface of the embedded friction section rod. The annular groove section is provided with multiple groups of independent annular grooves; the positioning table is arranged at the tail end of the annular groove section; the tail teeth are provided with multiple sets of independent ring grooves. The threaded section at one end of the
