The invention provides a lift rocking shaker. A front cross beam and a rear cross beam which are correspondingly arranged are fixedly connected between a left support and a right support, multiple non-circular rotary discs are connected between the front cross beam and the rear cross beam through a rotary shaft in a relative rotation mode, the rotary discs are arranged side by side, and the sizes of the rotary discs are different. The rotary shaft is connected with the cross beams in a relative rotation mode, the rotary shaft is fixedly connected with the rotary discs, and one end of the rotary shaft is in transmission connection with a rocking bar. Vertically-arranged springs are fixedly connected to the cross beams, the upper ends of the springs are fixedly connected with hollow test tube containing boxes with upward openings, the test tube containing boxes are erected on the rotary discs and located between the left support and the right support, shelves are fixedly connected to the interiors of the test tube containing boxes, and multiple test tube penetrating holes are longitudinally and transversely formed in each shelf in rows. The rotary discs are one or more of ovals, triangles and rectangles. The intersections of the rotary discs and the rotary shaft deviate from the centers of the rotary discs. Baffles are fixedly connected to the inner sides of the supports, and the test tube containing boxes are located in the regions defined by the baffles. The baffles are triangular or rectangular or trapezoidal.
