The invention relates to a synthetic lifting oil cylinder and a carrier thereof. A valve body and an oil cylinder main body are included, the valve body is provided with a manual piston cavity, an oil cylinder piston cavity and an oil duct, the oil cylinder main body is arranged in the oil cylinder piston cavity, and the oil cylinder is characterized by further comprising a machine pump assembly used for absorbing oil, and the inlet end of the machine pump assembly is communicated with an oil tank; a descending valve assembly is arranged at one end in the oil duct, a one-way valve assembly is arranged at the other end in the oil duct, and a reversing steel ball is arranged between the descending valve assembly and the one-way valve assembly; an operating handle is hinged to the valve body, one end of the operating handle is connected with the descending valve assembly, and the descending valve assembly is driven to move in the axial direction of the oil duct through rotation of the operating handle; and the outward end of the one-way valve assembly abuts against a one-way steel ball, and a port of an oil duct where the one-way steel ball is located is connected with the outlet end of the machine pump assembly through a pipeline. The manual piston cavity is communicated with the oil duct section where the reversing steel ball is located through the channel a, and efficiency is improved.
