Disclosed is a shears-fork type lifting mechanism which comprises an upper platform, a base, two outer support arms, two inner support arms, a cylinder and a lifting air bag. The shears-fork type lifting mechanism has the advantages that the lifting air bag plays a leading role in the initial stage of lifting, so that pressure borne by the cylinder in the initial stage of lifting is lowered greatly as compared with that of the existing limiting mechanism, and maximum lifting weight of the lifting mechanism can be further increased within the standard range of safety pressure; besides, since the lifting air bag is compressible and is tiny in occupied space, the lowest initial altitude of the lifting mechanism can reach the lowest altitude allowed by the geometric structure, and the application range of the lifting mechanism is widened; in addition, when the lifting mechanism is lowered into the maximum stroke range of the air bag, due to the presence of the lifting air bag, cushioning effect can be achieved, and vibration can be reduced greatly.
