The ring-type of cooperation, makes the contact area of the first convex tendon 1111 and the first groove 341 bigger, connects more stable, simple in construction, just
In assembling.It should be understood by one skilled in the art that the shape of the first convex tendon and the first groove is not limited thereto, other shapes
Shape also can reach propinquity effect.In addition, the vertical tangent-plane projection semicircular in shape of the first convex tendon 1111, makes it easier to slip into first
In groove 341.
3rd embodiment of the present utility model is related to a kind of optical lens.3rd embodiment and second embodiment are big
Cause is identical, is in place of the main distinction：In second embodiment, interior side ring surface 132 is provided with the first convex tendon 1111, the outer side ring of pressure ring
Face 34 is provided with the first groove 341.And in the embodiment of the utility model the 3rd, as shown in circled portion B in Fig. 8, convex tendon
It is opposite with the position that groove is set.
Specifically, as shown in Fig. 9,10, interior side ring surface 132 is provided with the outer side ring surface 34 of the second groove 1112, pressure ring
On be provided with the second convex tendon 342.Similarly, the second convex tendon 342 can engage with the second groove 1112, and the second convex tendon 342 is annular in shape,
Second groove 1112 is in the ring-type coordinated with the second convex tendon 342, the second convex tendon 342 is slid more easily into the second groove 1112,
This mode same structure is simple, and it is more convenient to assemble.
It will be understood by those skilled in the art that the respective embodiments described above are to realize specific implementation of the present utility model
Example, and in actual applications, can to it, various changes can be made in the form and details, without departing from spirit of the present utility model
And scope.
