The invention relates to a lead screw driving lifting platform with an auxiliary raising block. The lifting platform comprises a lower frame, an upper frame, two outer supporting arms and two inner supporting arms, and further comprises two raising plates, two pushing rods and a U-shaped frame. The front side faces of the two raising plates are each provided with a curve face or an inclined face. A connecting beam is arranged between the two raising plates to fixedly connecting the two raising plates. The bottoms of the two raising plates are provided with raising plate wheels respectively. The raising plate wheels make contact with the upper surface of a lower rail. The two pushing rods are fixedly connected to the rear end of the connecting beam. The connecting plate is arranged between the two pushing rods to connect the two pushing rods. A middle connecting plate of the U-shaped frame is provided with two axial holes. The portions, at the front end of the connecting plate, of the pushing rods are arranged in the axial holes in a penetrating mode. Lower idler wheels are arranged at the bottom of the U-shaped frame. The two side faces of the U-shaped frame are provided with hinge points respectively to be hinged to the lower ends of the two inner supporting arms. The lead screw driving lifting platform is safe and reliable, the driving power is lowered, and the lifting range is enlarged.
