Embodiment 1
[0031] see Figure 1-7 , the present invention provides the following technical solutions: a universal focus ring suitable for different lenses, including a focus ring body 2, the bottom of the focus ring body 2 is slidingly connected with a focus module, and the focus module includes several circles with diameters in order A focusing module is added, and the focusing module includes several movable rods 3 in a circular array.
[0032] Further, the bottom of the focus ring body 2 is provided with several circles of through holes 5 corresponding to the focus modules, and the diameter of the through holes 5 is 0.01 mm larger than that of the connecting rod 32 .
[0033] By adopting the above technical solution, the movable rod 3 is installed through the setting of the through hole 5 so that the movable rod 3 can slide in the through hole 5 .
[0034] Further, the movable rod 3 includes a focusing petal 31, a connecting rod 32 and a limiting block 33, wherein one end of the conn...
Embodiment 2
[0037] The difference between this embodiment and Embodiment 1 lies in: further, friction teeth 1 are provided on the circumference of the focus ring body 2 .
[0038] By adopting the above technical solution, it is convenient to rotate the focus ring body 2 .
[0039] Further, the implementation method of the universal focus ring applicable to different lenses according to the present invention includes the following steps:
[0040] (1) Friction teeth 1 are arranged on the circumference of the focus ring body 2 to facilitate the rotation of the focus ring body 2;
[0041] (2), the bottom of the focusing ring body 2 is provided with several circles of through holes 5, which is convenient for installing the movable rod 3;
[0042] (3) Put the lens 4 under the focus ring body 2, the focus ring body 2 presses the lens 4 downward, the edge of the lens 4 pushes the corresponding movable rod 3 upward, and the limit block 33 and the focus ring body 2 Contact for limit;
[0043] (4...
