| description | The utility model relates to an anti-vibration structure with two-gear focus fixing and lens group switching zooming. The anti-vibration structure is characterized by comprising a front fixing assembly, a focusing assembly, a middle fixing assembly, a zooming assembly and a rear fixing assembly which are sequentially connected from incident light to emergent light, the front fixing assembly, the focusing assembly, the middle fixing assembly, the zooming assembly and the rear fixing assembly are fixedly connected with a connecting bottom plate through flanges; the beneficial effects of the utility model are that the zooming assembly moves back and forth to realize the switching zooming of the two prime lenses, thereby greatly reducing the size and weight of the whole structure, and rapidly completing the switching of the two groups of focal lengths at the same time. The problem that two traditional prime lenses are bloated in size, the problem that a two-gear zoom lens is not high in repeated precision and the |
