Problems solved by technology

[0004] The focusing structure realizes the function of focusing through the cooperation of the screw 16 and the spring 18, but the spring 18 has a certain life span, thereby affecting the life span of the focusing structure; in addition, the screw 16 abuts against one side of the lens 10, so that both sides of the lens The force is uneven and tilted; the screw 16 is close to the lighting hole 1224, and it is easy to block the incident light of the lighting hole 1224 during manual operation, which makes it inconvenient to focus

Description

【Technical field】 [0001] The present invention relates to a focusing structure. 【Background technique】 [0002] With the development of multimedia technology, digital cameras and video cameras are more and more favored by consumers. While people are pursuing miniaturization of digital cameras and video cameras, they also put forward higher requirements for the imaging quality of the objects they shoot. The focus structure is a key component to ensure the clear effect of the recorded image, and it is used to adjust the distance between the lens and the image sensor so that the image plane falls on the imaging surface of the image sensor. [0003] Chinese Patent No. 200320125240 published on March 30, 2005 discloses a focusing structure. Please refer to FIG. 1 , the focusing structure includes a lens 10 , a lens holder 12 , an image sensor 14 , a screw 16 and a spring 18 . The lens mount 12 includes a first cylindrical portion 122 and a second cylindrical portion 124, wherei...
