Specific embodiment
In the view of whole accompanying drawings, corresponding reference markss represent corresponding part.
This utility model is further described in detail below in conjunction with the accompanying drawings, these accompanying drawings are simplified signal
Figure, only illustrates in a schematic way basic structure of the present utility model, and the direction being originally embodied as is with Fig. 1 directions as standard.
This utility model provides a kind of simple structure, easy to operate and installation is simpler, facilitates optical lenses to tie
Structure.
A kind of optical lenses structure of this utility model, mainly include optical lens main body 1, keeper 2, focusing ring 3,
Optical lens fixed seat 4, wherein：
Optical lens main body 1 mainly includes eyeglass 11, camera lens cylinder base 12, and eyeglass 11 adopts existing skill with camera lens cylinder base 12
Art, eyeglass 11 is embedded in inside camera lens cylinder base 12, and the tail surface of optical lens cylinder base 12 is provided with helicitic texture 121；
Keeper 2 is mainly used in optical lens main body 1 all the time in poised state, and moves on the same axis,
The first-class interval vertical of close optical lens body tail section helicitic texture 13 of optical lens main body 1 is convexly equipped with keeper 2, keeper
