Two through holes, often ranked second the corresponding tapered guide of through hole, be equipped with expander in second through hole, the expander it is interior
End is bonded with tapered guide, and the outer end of the expander is provided with the first groove, and it is logical often to ranked second adjacent in through hole two second
Screw body between hole is provided with second groove corresponding with the first groove, and the elastic ring is located at the first groove and second recessed
In groove.
Preferably, the outer face of the expander is concordant with the side face of screw body, set on the outer face of the expander
There is scalelike mark.
It often ranked second through hole preferably, described circumferentially shape be uniformly distributed and formed by four the second through holes.
Preferably, the cap body of the hammer rivet nut is made up of hammer cap body with the transition body for being integrally formed in hammer cap body front end,
The front end of the transition body is integrally formed with the body of rod of hammer rivet nut, and the diameter of the transition body is more than the diameter of first through hole, institute
The diameter for stating hammer cap body is more than diameter of the diameter less than screw body of transition body.
The beneficial effects of the utility model：The utility model by by the side face of screw body be provided with it is some ranked second it is logical
Hole, the corresponding tapered guide of through hole is often ranked second, expander, the inner of expander and tapered guide are equipped with the second through hole
Fitting, hammer rivet nut is tapped by hammer, hammer rivet nut is travelled forward, stretches out expander by tapered guide and contradict installing
On the hole wall in hole, the design of the through hole of front two rows second, it is possible to increase adapt to the scope in installation aperture, and expander and installation
The hole wall in hole contacts for face, increases contact area, compared with prior art, it is possible to increase fixed reliability, improves and adapts to installation
The scope in aperture.
Feature and advantage of the present utility model will be described in detail by embodiment combination accompanying drawing.
