Permanent non-overturning safety device for vehicle driving

The invention provides a permanent non-overturning safety device for vehicle driving. The permanent non-overturning safety device for the vehicle driving comprises a supporting rod, an automatic falling pin, a spring, balls and a supporting rod flat-shaped concave hole which are arranged inside a shell. The permanent non-overturning safety device for the vehicle driving is characterized in that angle hammers are sequentially connected with a hammer rod, an inverted U-shaped frame and a cone-shaped supporting rod, the lower end of the supporting rod is arranged below the transverse rod, the transverse rod is connected with a flat-shaped forcing pin, and a pin of the flat-shaped forcing pin is arranged in the supporting rod flat-shaped concave hole. When overturning occurs during the vehicle driving, the angle hammers are automatically inclined to the other end, the inverted U-shaped frame and the cone-shaped supporting rod are pushed forwards, the transverse rod and the flat-shaped forcing pin are supported, the flat-shaped forcing pins are separated from the supporting rod flat-shaped concave hole, the front end of the supporting rod slides onto the ground in moment, upward sliding of the supporting rod is forced to stop by the automatic falling pin, and the non-overturning is achieved under the condition that a vehicle is supported by the supporting rod.
