Description

Technical Field

[0002] The focus adjustment of an optical camera is to change the relative position of the camera lens and the object to change the focal length, thereby adjusting the clarity of the camera image, so that the adjusted focal length is convenient for focusing and shooting the object. In some laboratories, optical cameras are needed to shoot experimental equipment.

[0003] In order to facilitate the camera to shoot the test equipment, the camera is usually fixed on the top of the workbench so that the fixed component supports the camera to avoid the camera displacement affecting the clarity of the shooting during shooting. The object to be photographed is placed on one side of the camera. By driving the camera back and forth, the camera can be focused and the clarity of the object can be adjusted. Since the position and placement position of the object to be photographed are different, it is not convenient to quickly focus the camera. In order to meet the need to focus and shoot the camera at various places on the object, in view of the shortcomings of the existing technology, we propose a fast focusing mechanism to solve the above problems.
