As shown in fig. 1 to 3, the anti-loosening nut member provided in the present embodiment is a conventional nylon nut, and specifically includes a nut body 10, and internal threads 30 are correspondingly provided on an inner wall of the nut body 10.

Here, the nut body 10 is set to have an upper end face 101 and a lower end face 102 which are disposed opposite to each other, a notch 20 is formed around the nut body 10 near the upper end face 101, the notch 20 is formed at a position about 2mm from the upper end face 101, and the notch 20 extends in the axial direction of the nut body 10 without penetrating the nut body 10.

The cutting groove 20 is V-shaped in side view, and the included angle of the cutting groove 20 is 20-50 degrees, generally 21 degrees is selected, so that deformation is facilitated and locking is performed.

Here, the nut body 10 is divided into two parts by the slit 20, the upper half part is the upper end 11, the lower half part is the lower end 12, the thickness of the upper end 11 is smaller than that of the lower end 12, the upper end 11 is in a circular ring structure, deformation is facilitated, and the lower end 12 is in a conventional hexagonal structure, so that force application screwing is facilitated.
