Speed-change oscillation device for cell culture

The invention discloses a speed-change oscillation device for cell culture. The device comprises a machine body, wherein a mounting cover is rotationally mounted on the machine body; the mounting cover is of a hollow structure; a plurality of mounting grooves are formed in the machine body; fixing grooves are formed in the mounting grooves; large clump weights and small clump weights are fixedly connected in symmetry on both sides of bottoms of the fixing grooves; culture mediums are connected with the fixing grooves in a clamped manner; a driving mechanism is arranged below each mounting groove; the driving mechanism comprises a uniform speed motor and a driven gear; and a fixing shaft is fixedly connected below each fixing groove. Fan-shaped gears are driven by the uniform speed motors,and the fixing grooves are designed into structures of which the gravity centers are deviated from centers, so that the fan-shaped gears and the driven gears can be continuously rotated under the effect of inertia after being
