Replaceable lens device applied to microscope

The utility model discloses a replaceable lens device applied to a microscope, which comprises an upper identification mechanism arranged on a zoom lens cone and a suspension limiting mechanism arranged on an objective lens component, and the suspension limiting mechanism is in sliding fit with the objective lens component through a ball under the limiting and fixing of the upper identification mechanism. Friction between the suspension limiting mechanism and the upper recognition mechanism and friction between the suspension limiting mechanism and the objective lens component in the spiral matching process of the objective lens component and the lens cone are reduced, installation is facilitated, and the installation efficiency is improved; based on the structure of the designed suspension limiting mechanism, the peripheral mechanism of the objective lens is simple; based on the limiting and fixing of the upper recognition mechanism and the suspension limiting mechanism, the objective lens and the lens barre
