The utility model discloses a spiral oil press with an adjustable pressing ratio, which comprises a fixed cylinder, a pressing screw, a pressing cage and a pressing cage adjusting component, the pressing cage is fixedly arranged inside the fixed cylinder, and the pressing screw is rotatably arranged inside the pressing cage through a screw rod; the squeezing cage is composed of a plurality of arc-shaped squeezing strips arranged in the circumferential direction in a surrounding mode. One end of each arc-shaped pressing strip is pressed and fixed through a positioning assembly, the outer side of the gap between every two adjacent arc-shaped pressing strips is connected with an arc-shaped rubber plate through a sealing pressing assembly, and the pressing cage adjusting assembly is arranged at one end of the screw rod so as to be used for stretching and supporting the other end of the arc-shaped pressing strip. According to the utility model, one end part of the arc-shaped pressing stripcan be supported at a proper position by the supporting rod by rotating the adjusting hand wheel, so that the pressing ratio of oil materials can be correspondingly adjusted. The oil press is simple in structure and convenient to operate, the occupied space of the oil press is reduced, oil of different types can be pressed, and the use efficiency of the oil press is greatly improved.
