The invention belongs to the technical field of embryo storage, and particularly relates to an embryo storage stair barrier-free jacking trolley which comprises a frame, a driving mechanism is arranged on the top face of the lower end of the frame and comprises a limiting seat, an inner cavity is formed in the limiting seat, a cylindrical rack penetrates through the top face of the limiting seat in a sliding mode, and the cylindrical rack is arranged on the top face of the limiting seat in a sliding mode. The upper end of the cylindrical rack is provided with a supporting arm mechanism, the supporting arm mechanism is provided with a limiting mechanism, the limiting mechanism comprises a second sleeve, the second sleeve is connected with the lower end of the cylindrical rack in a sleeving mode and does not make contact with the lower end of the cylindrical rack, and the bottom face of the second sleeve is fixed to the top face of the limiting base. According to the scheme, the situation that workers need to work aloft is avoided, the danger of aloft work is avoided, the labor intensity of the workers is relieved, then the situation of accidental falling is avoided, the rejection rate is reduced, the embryo storage quality is guaranteed, and the transfer efficiency is improved.
