Problems solved by technology

[0005] The present invention aims at the above-mentioned deficiencies in the prior art, and provides a dismantling and recycling device for power lithium batteries, which solves the problem that the position of the lens inside the lens cannot be moved, so that people can make the sleeve slide in the sliding position by flipping the slip ring. The inner movement of the ring changes the position of the lens inside the sleeve to adjust the focal length of the lens, which is suitable for people to use in different scenes

Abstract

The invention discloses a wide-angle optical lens. The optical lens comprises a lens body and a lens cover, a fixing shell sleeves the lens body, and a lens fixing unit is arranged in the fixing shell; a sleeve is arranged outside the lens fixing unit, and a round base is arranged in the sleeve; positioning rods are arranged at the two ends of the radial line of the round base respectively, a sliding ring is arranged between the fixing shell and the sleeve, and the sliding ring is movably connected with the sleeve through threads; a fixed clamping ring is arranged in the sleeve, an elastic part is arranged outside the fixed clamping ring, and the elastic bottom is tightly fixed to the inside of the sleeve. The wide-angle optical lens can actively adjust the focal length of an internal lensaccording to the preference of a user so as to meet different photographing requirements.

Description

technical field [0001] The invention relates to the field of optical lenses, in particular to a wide-angle optical lens. Background technique [0002] A wide-angle lens is a photographic lens with a shorter focal length than a standard lens, a larger viewing angle than a standard lens, a longer focal length than a fisheye lens, and a smaller viewing angle than a fisheye lens. Wide-angle lenses are divided into ordinary wide-angle lenses and ultra-wide-angle lenses. The focal length of ordinary wide-angle lenses is generally 38-24 mm, and the viewing angle is 60-84 degrees; the focal length of ultra-wide-angle lenses is 20-13 mm, and the viewing angle is 94-118 degrees. Because the focal length of the wide-angle lens is short and the angle of view is large, a larger area of ​​the scene can be captured within a shorter shooting distance. The focal length of the lens of the wide-angle digital camera is very short, the angle of view is wide, but the depth of field is very deep,...
