Abstract

The invention provides a camera capable of realizing focusing well. The camera comprises a lens, a lens mount, and a sensitive chip, wherein the lens is fixed on the lens mount. Besides, the camera is characterized in that: the camera also includes a sensitive chip permanent seat, wherein the sensitive chip is fixed on the sensitive chip permanent seat; screw holes and screws passing through the screw holes are arranged on the sensitive chip permanent seat; guide pillars with internal screw threads are arranged on the lens mount, wherein the guide pillars correspond to the screws; and springs that are used for supporting the sensitive chip permanent seat are sleevedly connected at peripheries of the guide pillars. According to the camera capable of realizing focusing well, the lens position can be maintained to be unchanged; an objective of focusing can be achieved by adjusting the position of the sensitive chip; therefore, not only can a clear image be obtained, but also fastness of the lens can be ensured.

Description

technical field [0001] The invention relates to the technical field of cameras, in particular to a camera with adjustable focus. Background technique [0002] In order to obtain a clear image, a traditional camera includes a lens, a lens holder, a photosensitive chip, a circuit board, etc., and the lens is connected to the lens holder through threads. When installing the camera, in order to obtain a clearer image, it is necessary to adjust the distance between the lens and the photosensitive chip. The traditional camera adjusts the distance between the lens and the photosensitive chip by adjusting the length of the threaded connection between the lens and the lens holder to achieve The purpose of adjusting the focal length. [0003] Although the traditional camera can complete the focus adjustment, the inventor found that the traditional camera still has the following problems in the process of research and development: when installing the camera, the distance between the l...
