Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, an embodiment of the present invention provides a technical solution: the utility model provides a novel stud assembly, includes spiral shell head 1 and

screw rod

2, 2 gomphosis of screw rod are in the both ends of spiral shell head 1, the both ends of spiral shell head 1 are equipped with gomphosis groove 4, be equipped with first locking hole 3 on the

gomphosis groove

4, 2 one end of screw rod are equipped with spacing dish 5, be equipped with the gomphosis post 6 on the spacing dish 5, be equipped with second locking hole 7 on the cylinder of gomphosis post 6.
