At present, the commonly used automobile license plate fixing and sealing device comprises: the device comprises a concave base, a buckle spring and an upper cover; wherein, the spring is pressed in the concave base. When the automobile license plate is installed, a mounting hole reserved in the middle of the automobile license plate corresponds to a screw hole reserved on an automobile, and a common nut sequentially penetrates through the concave base, the mounting hole on the automobile license plate and the screw hole on the automobile and is fixed on the automobile; the upper cover with the carved Chinese characters is pressed in the concave base and touches the buckling spring, and the buckling spring is touched to buckle and lock the inward folded edge. However, the vehicle license plate fixing and sealing device is made of ultra-thin zinc alloy and the like, and a zinc alloy base; the upper cover can be finished only by electroplating in the manufacturing process, but the discharge of electroplating wastewater causes serious environmental pollution and is inconsistent with the national conditions of China.
In addition, the buckle spring in the concave base of the conventional license plate fixing device is generally made of sheet iron through stamping, and has no elasticity at all. In the running process of a vehicle, the situation that an upper cover carved with Chinese characters is shaken off is often caused by shaking and fluctuation of the vehicle, so that the phenomenon that the license plate of the vehicle is stolen or a fake license plate of the vehicle is artificially installed is caused. Especially, if the traffic accident happens, the accident vehicle escapes, which causes great difficulty for the public security traffic police department to catch the accident vehicle. Some lawbreakers use the fake cards to complete crime and illegal activities, which seriously endangers social security.
