The invention discloses a novel screw turning device. The novel screw turning device is characterized in that a front vertical plate and a rear vertical plate are respectively fixed by the aid of four struts which are close to four corners of a plate surface, a chain sleeves the four struts to form a rectangular structure, screwdrivers are arranged at the front ends of gear shafts, the bottoms of driven gears are meshed with the top of the chain, the gear shafts are penetratingly inserted in corresponding mounting holes, the front end and the rear end of an operation shaft are respectively penetratingly inserted in the front vertical plate and the rear vertical plate, and the left side of an operation gear is meshed with the right side of the chain. The gears are meshed with one another, so that the operation gear can interact with the chain and the driven gears, and a plurality of screws can be simultaneously turned. The novel screw turning device has the advantages of flexibility in operation, convenience in use and high work efficiency.
