Surface protection structure of optical lens

The utility model discloses a surface protection structure of an optical lens, and relates to the field of optical lens protection. The surface protection structure of the optical lens comprises an optical lens protection frame fixedly connected to a lens body, and is characterized in that a cover plate used for protecting the optical lens is movably connected to the optical lens protection frame in a clamped mode, an air blowing channel is formed in the optical lens protection frame, a high-pressure fan is arranged at the bottom of the lens body, and the air blowing channel is communicated with the air blowing channel. And the output end of the high-pressure fan is communicated with the air blowing channel. When the surface protection structure of the optical lens is used for protecting the optical lens, the optical lens protection frame and the cover plate are directly adsorbed and fixed, meanwhile, when dust is attached to the surface of the optical lens, the high-pressure fan is used for removing high-pre
