【Embodiment】
Embodiment one
Refering to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of Anti-loose fastener of the invention, including including bolt 1, the first spiral shell
Female 2, second nut 3, the 3rd nut 4, the bolt 1 are made up of bolt head 11 and stud 12, and stud 12 is connected with bolt head 11,
The afterbody of stud 12, which has, main external screw thread 13 on main groove 15, stud 12, there is the first internal thread 21 in first nut 2, main outer
Screw thread 13 cooperates with the first internal thread 21, and having outside the first nut 2 in first external screw thread 22, second nut 3 has
Two internal threads 31, the second internal thread 31 cooperates with the first external screw thread 22, there is auxiliary flute 35, the second spiral shell on the second nut 3
