The utility model discloses an oil pumping unit hair braid fixing apparatus which comprises a suspension block, adjusting through holes, a fixing boss, a fixing cylindrical cavity, an upper cylindrical backing ring, a ball thrust bearing, a lower cylindrical backing ring, a screw-in thread, a limit cylindrical ring, a screw-in clamp hole, a hair braid and a cylindrical hanging block. The oil pumping unit hair braid fixing apparatus is simple and clear in structural principle, according to a traditional hair braid, rotating tension generated by a steel cable cannot be relieved due to stress tension, and twisting is caused. The hanging block at the lower end can rapidly and radially rotate through the thrust bearing, the root cause of twisting is solved, unnecessary friction loss is avoided by the double adjusting through holes, accidents of an oil pumping rod in the vertical reciprocating process are decreased, and production efficiency is improved.
