Road roller starting limiting mechanism

The utility model belongs to the technical field of electrically-driven road rollers, and particularly provides a vehicle starting limiting mechanism of a road roller. Specifically, a key switch is connected with a movable contact of a first normally-closed relay contact, a normally-closed contact of the first normally-closed relay is connected with a movable contact of a second normally-closed relay, a normally-closed contact of the second normally-closed relay is connected with a starting motor, and a second end of an oscillation starting button is connected with a coil of a normally-open relay. The input end of the normally-open relay is connected with the second end of the storage battery relay contact, one path of the output end of the normally-open relay is connected with the first end of the first normally-closed relay coil, and the second end of the first normally-closed relay coil is grounded. And driving in the oscillation starting process is avoided, so that personal safety and construction quality
