Abstract
The utility model discloses an automatic return device which comprises an upper cover and a base plate. The upper cover is connected with the base plate through screws. A hole base is arranged in the middle of the base plate. A rotatable hollow cylinder is arranged in the hole base. The other end of the hollow cylinder extends out corresponding to a through hole in the upper cover. The outer surface of the hollow cylinder extends outwards to form two symmetric return plates. A first screw is arranged on the end portion of one return plate. A second screw is arranged on the end portion of the other return plate. A third screw and a fourth screw are respectively arranged in the middle portions of two corresponding sides of the base plate. The first screw is connected with the third screw through a first spring. The third screw is connected with the second screw through a second spring. The second screw is connected with the fourth screw through a third spring. The fourth screw is connected with the first screw through a fourth spring. Through adoption of the four springs, the hollow cylinder enables the return plates to return under the action of spring force and tension force. Consequently, the automatic return device enables a vehicle to regularly run along the straight line.
