High-strength nut with anti-loosening function

The high-strength nut with the anti-loosening function comprises a nut body, a reinforcing connecting ring is integrally formed at one end of the nut body, internal threads of the nut body extend to the inner wall of the reinforcing connecting ring, and a plurality of arc-shaped clamping plates for clamping bolts are movably arranged on the inner wall of the reinforcing connecting ring. Threaded limiting strips matched with external threads of the bolts are arranged on the inner walls of the arc-shaped clamping plates, a containing groove used for containing the multiple arc-shaped clamping plates is formed in the end, away from the nut body, of the reinforcing connecting ring, and an adjusting mechanism used for adjusting the multiple arc-shaped clamping plates is arranged on the reinforcing connecting ring. The threaded limiting strips arranged on the inner walls of the arc-shaped clamping plates are matched with the threads on the outer wall of the bolt for limiting, so that the stability of connection bet
