According to upper described a kind of double-leg nail, wherein, the U-shaped or V-type of described rivet nut.
According to upper described a kind of double-leg nail, wherein, inclined-plane described in two is separately positioned on the positive front side of one of them nail pin of described rivet nut, the positive rear side of another nail pin, mutual crossed-symmetrical, after entering object, two nail pin are at the resistance by inclined-plane with under leading, the power that nail pin is subject to inclined-plane reverse, make it that trail change occur, make two nail pin form the grip force be staggered front to back, enhance the fastness between rivet nut and article.
According to upper described a kind of double-leg nail, wherein, inclined-plane described in two is separately positioned on the left side of one of them nail pin of described rivet nut, the right side of another nail pin, opposing symmetry, after entering object, two nail pin are at the resistance by inclined-plane with under leading, the power that nail pin is subject to inclined-plane reverse, makes it that trail change occur, two nail pin is drawn in centre, relative distance reduces, and strengthens the fastness between rivet nut and article.
According to upper described a kind of double-leg nail, wherein, inclined-plane described in two is separately positioned on the right side of one of them nail pin of described rivet nut, the left side of another nail pin, relative symmetry, after entering object, two nail pin are at the resistance by inclined-plane with under leading, the power that nail pin is subject to inclined-plane reverse, makes it that trail change occur, two nail pin is opened outward, relative distance increases, and strengthens the fastness between rivet nut and article.
Positive front side described in above-mentioned, positive rear side, left side and right side are that the schematic front view of three kinds of embodiments in Figure of description is as reference standard.
The utility model gives prominence to compared to existing technology and useful technique effect is: rivet nut is in the movement process entering the plank degree of depth, nail pin is at the resistance by inclined-plane with under leading, nail pin is respectively by the extruding force that inclined-plane is reverse, make it that trail change occur, make two nail pin deformation (opening increases or draws in); Follow closely on pin in addition and be provided with hangnail, make that nail pin is strong under the effect of hangnail after entering plank prevents exiting of rivet nut; Simultaneously in conjunction with inclined-plane with nail pin on hangnail, its two structures mutual dislocation, enhances the fastness of rivet nut, makes rivet nut be difficult to be pulled out, the connection between two article more firmly, more secure.
