Automobile expansion rivet is a commonly used connector, and its working principle is to fix the connector through expansion. The specific working principle is as follows:

1. Drilling: First, drill holes on the two parts to be connected to ensure that the aperture matches the diameter of the expansion rivet.

2. Install the expansion rivet: insert the expansion rivet into the hole of one part, and then stretch the tail of the expansion rivet with a special tool to expand and fill the hole of the other part.

3. Expansion fixation: When the tail of the expansion rivet is stretched, the body of the expansion rivet will expand to form a solid connection, which will firmly fix the two parts together.

4. Compaction: Finally, cut off or compact the tail of the expansion rivet to make it flush with the surface of the connector, so as to ensure the cleanliness and safety of the connector.

Through the working principle of expansion rivet, the connector can be fixed quickly and simply, which is suitable for the fixing and connection of automobile body, interior parts, engine compartment and other parts, and improves the overall structural stability and safety of the automobile. Choosing the appropriate expansion rivet type and the correct installation method can ensure the firmness and stability of the connector and improve the service life and safety of the automobile.
