The invention discloses a control handle for a hand hydraulic carrier. The control handle for the hand hydraulic carrier comprises a rod body and an annular handle connected to the rod body. A pinching handle is installed on the rod body and connected with a hydraulic lifting device of the hand hydraulic carrier through a transmission element. The rod body is connected with a pump body of the hydraulic lifting device through a pin shaft. The rod body is composed of a press rod part and a swing part which are movably connected. Lug plates on the two sides of the press rod part are connected with the pump body through pin shafts. The swing part is provided with a swing rod body and a sector block fixedly connected with the lower end of the swing rod body into a whole. A driving piece and a driven piece of a cam mechanism are composed of the sector block and a pump core of the pump body. In the cam mechanism, the sector block swings leftwards and rightwards, and the corresponding pump core moves downwards to supply oil or moves upwards to absorb oil. By the adoption of the control handle, carrier lifting time is shortened and meanwhile the operation range is reduced.
