Description

Primary and secondary button

Technical Field

The utility model relates to a primary and secondary buckle, its applicable assembly in automobile parts.

Background

Generally, the fitting of the automobile interior is usually fixed by screws. The fixed installation mode has the advantages of stable and reliable matching due to high installation strength. But also has the defects of complex installation process, long installation time and the like. Therefore, recently, snap fasteners have been used in the industry to replace screws for assembling interior accessories. When the conventional snap fastener is assembled as a large-aperture fastener, the clamping leg is easy to yield and lose efficacy, and the snap fastener and the connecting piece are easy to fall off due to vibration in the driving process of an automobile, so that the fastening effect is lost.
