Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
See Fig. 1~4, cyclic annular universal lock steel plate, with integrally formed steel plate ontology 1, the shape of steel plate ontology 1
It is adapted with the shape of bone, which also has there are two spherical split ring 2, is provided on steel plate ontology 1 and opens with spherical shape
Two spherical pores 3 that choma 2 matches, being provided on the inner wall of spherical pore 3 prevents spherical split ring 2 from doing week in spherical pore 3
To the convex block 4 of rotation, the opening of spherical split ring 2 corresponds to the convex block 4 of spherical pore 3.Spherical split ring 2 can be in corresponding spherical shape
Do the movement swung up and down in hole 3, the angle that spherical split ring 2 can be swung up and down in corresponding spherical pore 3 is -15 °~+
15°。
The mid diameter of spherical split ring 2 is greater than its both ends diameter.It is additionally provided with and locks on the inner wall of spherical split ring 2
The screw thread that the screw thread head of a nail of screw 5 matches struts spherical split ring 2 gradually until spherical when lock screw 5 is gradually locked
