[specific embodiment]
Refering to fig. 1 to Fig. 4, a kind of elastic locking rivet nut of the present invention, including screw head 11, the first rank bar 12 and second-order
Bar 13, the side wall of the screw head 11 are equipped with grooving 112, and the top edge of the screw head 11 is equipped with convex block 111, described
First rank bar 12 is hexagon, and the second-order bar 13 is cylinder, and the bottom end of the second-order bar 13 is equipped with guide part
131, the upper and lower ends of the first rank bar 12 are connected with screw head 11 and second-order bar 13 respectively, are equipped in the screw head 11
First through hole 113, the first rank bar 12 is interior to be equipped with the second through-hole 121, is equipped with 132 He of third through-hole in the second-order bar 13
Fourth hole 133, the quantity of the grooving 112 are at least one, the depth of the grooving 112 be greater than the wall thickness of screw head 11 and with
First through hole 113 connects, and the convex block 111 is annular, and the quantity of the convex block 111 is identical as grooving 112, the convex block
111 position is located on the position of grooving 112, the first through hole 113, the second through-hole 121, third through-hole 132 and the 4th
Through-hole 133 connects, and the first through hole 113 is identical with the diameter of third through-hole 132 and is greater than the diameter of fourth hole 133,
The diameter of second through-hole 121 is greater than the diameter of first through hole 113 and third through-hole 132, the first through hole 113, third
