Telephoto lens auxiliary support

Abstract

The invention discloses a telephoto lens auxiliary support. The telephoto lens auxiliary support comprises a telephoto lens, a fixed box, a first telescopic rod, a second telescopic rod, a third telescopic rod, a fourth telescopic rod, a second round hole, a second clamping rod, a first stud, a first clamping rod, a second stud, a connecting base, a third stud, a first fixing plate, a fourth stud,a nut, a sleeve, a motor, a belt, a second rotary rod, a brush rod, a second fixing plate and a first round hole. The telephoto lens auxiliary support is reasonable in structure, convenient to detachand fix; the telephoto lens auxiliary support has the automatic cleaning function because the brush rod is driven to rotate by the motor and the angle of a hinge is adjusted through the motor, and the purposes that dust is prevented from accumulating on the outer wall of the lens and the outer wall of the lens is prevented from blurring are achieved; and because of the mutual connection relationamong the six telescopic rod mechanisms, it is more convenient to adjust the height and the angle of the telephoto lens and to install or withdraw the telephoto lens support, and people can shoot quicker and more conveniently.

Description

technical field [0001] The invention relates to an auxiliary lens bracket, in particular to an auxiliary lens bracket for a telephoto lens, and belongs to the technical field of lens brackets. Background technique [0002] A telephoto lens refers to a photographic lens with a longer focal length than a standard lens. The long focal length lens is divided into two types: an ordinary telephoto lens and a super telephoto lens. However, it is far larger than the standard lens. Taking the 135 camera as an example, the photographic lens with a lens focal length from 85 mm to 300 mm is an ordinary telephoto lens, and the lens above 300 mm is a super telephoto lens. [0003] Most of the current telephoto lens holders cannot be cleaned automatically. Due to the different types of telephoto lenses, most of them are not easy to clean the lens, and it is easy to cause dust to accumulate on the outer wall of the lens, making the outer wall of the lens blurred; the current telephoto lens ...
