Auxiliary device for manual needle setting of atomic force microscope

The utility model relates to an auxiliary device for manual needle setting of an atomic force microscope. The device comprises an observation part and a focusing part, the main body structure of the focusing part comprises a base table, a lifting column, a supporting table, a base, a sliding rail, a sliding rail baffle plate, a sliding beam baffle plate and a sliding beam; the observation part comprises a convex lens, a supporting column and a lens frame; according to the device, the main body part of the convex lens or the magnifying lens is combined with the three-dimensional moving slide rail, and the slide rail can independently move up and down, back and forth and left and right, so that the focal length adjustment between the convex lens and a sample is realized. According to the utility model, the risk of probe damage and the experiment cost during the operation of researchers can be reduced. 本实用新型为一种用于原子力显微镜手动下针的辅助装置。该装置包括观测部和调焦部；所述的调焦部的主体结构包括：基台、升降柱、支撑台、基座、滑轨、滑轨挡板、滑梁挡板和滑梁；所述的观测部的组成包括：凸透镜，支柱和镜框；该装置将凸透
