After the two sets of adjacent connecting columns 7 are fitted together, the connecting columns 7 and the liquid collecting tank 6 are fixed with bolts 8. The outer wall of the oil pressing barrel 2 has a smaller diameter near the lower end. After the liquid collecting tank 6 is installed, the inner wall is flush with the outer wall of the base 1, so that the produced oil flows from the oil through hole 3 into the liquid collecting tank 6. At this time, the piston rod of the hydraulic cylinder 41 extends, driving the connecting plate 43, the connecting rod 44 and the pressing cover 47 upward.
