1. An abrasive water jet nozzle for strengthening, comprising:
a chamber (N1), providing a mixing space; and
a strengthening mixing assembly, providing a strengthening mixing of water with abrasive entering said chamber (N1),
wherein the strengthening mixing assembly includes a fluid passage (101) and a water stopper block (102),
wherein the water stopper block (102) is located in an eccentric position on one side of the chamber (N1), and an outlet of the fluid passage (101) is directed towards the water stopper block (102); and
wherein the water stopper block (102) has an impact surface (102a) and a dispersion surface (102b), the impact surface (102a) is curved, the dispersion surface (102b) is symmetrically disposed on both sides of the impact surface (102a), the dispersion surface (102b) extends outward from the impact surface (102a) to an inner wall of the chamber (N1), and the dispersion surface (102b) has an arcuate transition with the inner wall of the chamber (N1).
