The invention discloses a chain shear fork type lifting platform. The chain shear fork type lifting platform comprises a base plate, a shear fork and a lifting platform body. The lifting platform body is connected with the base plate through the shear fork. The chain shear fork type lifting platform is characterized in that the lifting platform further comprises a chain wheel, a motor reducing gear, a purpose-made open type one-way bent chain and a chain connecting base; the purpose-made open type one-way bent chain comprises a plurality of continuous chain links, and each chain link comprises an upper hinge shaft, a lower hinge shaft, two symmetrical outer chain plates, two symmetrical inner chain plates and two roller sleeves; the outer chain plates are provided with upper circular holes I and lower circular holes I, and inner protrusions are arranged on the right sides of the outer chain plates; the inner chain plates are provided with upper circular holes II and lower circular holes II, and outer protrusions are arranged on the right sides of the inner chain plates; the middle parts of the upper hinge shafts and the middle parts of the lower hinge shafts are each sleeved with one roller sleeve. The chain shear fork type lifting platform is novel in structure, high in speed, high in precision, small in noise, easy to adjust and mount, low in cost and long in service life.
