The invention discloses a scissor fork type lifting structure. The scissor fork type lifting structure is characterized by comprising upper scissor fork units, lower scissor fork units and a lifting oil cylinder, the multiple upper scissor fork units are sequentially hinged from bottom to top, the multiple lower scissor fork units are sequentially hinged from bottom to top, and each lower scissor fork unit comprises two first outer scissor fork pipes, two first inner scissor fork pipes arranged between the two first scissor fork pipes, and a lower scissor fork shaft used for connecting the first outer scissor fork pipes and the first inner scissor fork pipes. By means of the upper scissor fork units with the small width, on the premise that the lifting height is guaranteed, the weight borne by the lifting hydraulic cylinder is reduced by reducing the thickness of the upper scissor fork units, the equipment efficiency and safety are improved, and the supporting stability is guaranteed through the lower scissor fork units with the large width.
