The invention relates to a focusing structure of a coarse-fine-adjustment coaxial microscope. The focusing structure comprises a coarse tuning gear wheel (3), a fine tuning shaft (2), a tooth bar sleeve (1), a coarse tuning hand wheel (8), and a fine tuning hand wheel (9), wherein the tooth bar sleeve (1), the coarse tuning hand wheel (8), and the fine tuning hand wheel (9) are installed on a microscope body (14) axially. A fixed center wheel (4) is fixedly connected to one end of the tooth bar sleeve (1) between the tooth bar sleeve (1) and the coarse tuning hand wheel (8); and a connecting sleeve (5) sleeves the outer wall of one end, arranged inside the cavity of the fixed center wheel (4), of the coarse tuning gear wheel (3). A transmission mechanism includes a wave-shaped spring washer (10) and a fixed nut (11); the fixed nut (11) cooperates with a thread formed at the outer side of the end portion of the coarse tuning gear wheel (3); and the wave-shaped spring washer (10) is arranged between the inner wall of the connecting sleeve (5) and the fixed nut (11). A gear wheel is arranged at the outer wall of one end of the fixed center wheel (4); a center wheel (13) is arranged at the outer wall of the fine tuning shaft (2); and the fine tuning hand wheel (9) is fixedly connected with the end portion of the fine tuning shaft (2).
Description
technical field [0001] The invention relates to a microscope, in particular to a focusing structure of a coarse and fine adjustment coaxial microscope. Background technique [0002] The WW type (double planetary wheel external meshing structure) used in the focus structure of the existing coarse and fine adjustment coaxial microscope is not only complicated in structure, but also its transmission efficiency will continue to decrease with the increase of the microscope's service time; there is also a The focusing structure of the coaxial microscope with coarse and fine adjustment is equipped with rolling bearings inside, and the transmission efficiency of this microscope is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a focusing structure of a coarse and fine adjustment coaxial microscope with high transmission efficiency and simple structure. [0004] In order to solve the above-mentioned technical probl...
