For reaching aforesaid purpose, the utility model provides a kind of anticreep nut, is a polygonal block, and its central authorities run through and are provided with an interior threaded hole, and it is characterized in that: this interior threaded hole outer openings is axially offered at least one section special-shaped breach; So that can carry out spinning, make its deformable material that is spun expansion press to and fill up at least one special-shaped breach of this interior threaded hole outer openings, and form both fixing by the bolt outer end that spinning tool pair and anticreep nut screw togather.
The utility model secondary objective is to provide a kind of anticreep nut, and wherein this different v notch v is the both-side opening that runs through this interior threaded hole.
Another purpose of the utility model is to provide a kind of anticreep nut, and wherein a disc is radially extended in this anticreep nut bottom.
The utility model purpose again is to provide a kind of anticreep nut, and wherein the opening shaft of this interior threaded hole is to offering at least two pairs of special-shaped breach relatively.
The another purpose of the utility model is to provide a kind of anticreep nut, should the abnormity breach be to be semicircle wherein.
The beneficial effects of the utility model are:
Anticreep nut of the present utility model, it can axially offer at least one section special-shaped breach to interior threaded hole by the opening of a nut, to axle bolt outer end during via the spinning of tool, make its deformable material that is spun expansion press to breach, the breach of nut opening is filled up by the protrusion material of the outer end of axle bolt destruction, and form both fixing, to reach anti-loose function.
