Abstract

The utility model provides a camera filter fixing structure, which relates to the technical field of photography, and comprises a fixing frame and at least two fixing devices, the fixing frame comprises an inner frame and an outer frame, the inner frame is fixedly connected with a camera lens, the outer frame is fixedly connected with a filter, the fixing devices are arranged on the inner frame, and the fixing devices are arranged on the outer frame. A fixing device is arranged on one side of the inner frame and used for fixing the filter on a camera lens, and the filter solves the problems that an existing filter fixes the filter and the lens through a rubber ring, and due to the fact that the rubber ring cannot be adjusted, the filter can only be specially used on one camera, and universality is poor.
