The invention relates to the technical field of transmission, and provides a connecting rod type lifting device. The connecting rod type lifting device comprises an upper adapter plate, a lower adapter plate, two connecting rod sets which have the same structure and hinged to each other, and a plurality of hinge pins; each connecting rod set is used for connecting the upper adapter plate and the lower adapter plate and comprises four connecting rods which are sequentially hinged by an end-to-end manner; the hinge pins are used for connecting the connecting rods as well as connecting the connecting rods with the upper adapter plate and the lower adapter plate; the connecting rods are of different length. The connecting rod type lifting device has the advantages and effects that the length and position allocation of the connecting rods are changed to enable the connecting rod type lifting device to be folded during being retracted, and thus the space utilization rate can be greatly increased; meanwhile, the quality of the connecting rod type lifting device can be reduced, and the load of a driving device can be decreased; on the premise that the stability is not influenced, the device has the characteristics of being simple in structure, convenient to mount and high in cost performance, and the applicable scope of the connecting rod type lifting device can be expanded.
