The invention relates to a truck cab hydraulic overturning manual-electric integrated pump, which comprises a pump body, an oil tank installed at one end of the pump body, and a motor installed at theother end of the pump body and communicated with the oil tank. A piston rod is arranged in the pump body; the pump body is provided with a rocking handle assembly which is connected with the piston rod and drives the piston rod to move up and down and an air pressure exhaust port which is arranged at an interval with the rocking handle assembly; an oil injection screw plug assembly is arranged atthe air pressure exhaust port; an oil suction port communicated with the interior of the oil tank is formed in the pump body; an oil suction one-way valve is arranged at the oil suction port; the other side of the pump body is provided with a first connector assembly and a second connector assembly which are communicated with the interior of the pump body and used for being connected with an overturning cylinder. One side of the pump body is provided with a pressure retaining valve at a position corresponding to the transmission shaft; the oil injection screw plug assembly comprises an oil injection screw plug, an oil injection screw plug blocking cover is arranged at one end of the oil injection screw plug, an exhaust channel communicated with the outside is arranged on one side of the oil injection screw plug, and an air exhaust and suction structure communicated with the exhaust channel is arranged at the other end, opposite to the oil injection screw plug blocking cover, of the oil injection screw plug.
