The invention discloses an anti-thread-slipping double-bolt-head bolt and a using method thereof, relates to the technical field of double-bolt-head bolts, and solves the problem that the double-bolt-head bolt is not easy to take out from a threaded hole after thread slipping in the using process of the double-bolt-head bolt. The anti-slipping double-bolt-head bolt comprises a stud, connecting mechanisms are fixedly welded to the upper end and the lower end of the stud correspondingly, pulling mechanisms are arranged on the end faces of the connecting mechanisms in a matched mode, and external threads are fixedly arranged on the surfaces of the upper section and the lower section of the stud correspondingly; and movable clamping mechanisms are movably arranged on the two sides of the interior of the connecting mechanism. The external threads are fixedly arranged on the peripheries of the surfaces of the upper side and the lower side of the stud, the peripheries of the two ends of the connecting mechanism are
