Beschreibung
Zusammenfassung:	The utility model relates to an anti-fatigue high-strength main bearing bolt which comprises an installation disc, a bearing is fixedly installed on the top of the installation disc, a bolt is movably installed on the top of the bearing, an inserting groove is formed in the position, located at the bottom end, of the outer surface of the bolt, and a fastening mechanism is arranged in the installation disc. According to the anti-fatigue high-strength main bearing bolt, by arranging the fastening mechanism, during installation, a rotating rod is rotated firstly, the rotating rod drives a driving gear to rotate, the driving gear drives a driven gear to rotate, the driven gear drives a threaded rod to rotate, and under rotation of the threaded rod, two inserting rods move in the opposite directions on the outer surface of the threaded rod; when the driving gear rotates, the limiting pawl and the swing rod swing between the two limiting pieces through the auxiliary rod, so that the limiting pawl is separated from
