In the above-mentioned connection assembly, the limiting clamping plate is in a circular plate shape, a clamping groove is formed in the outer peripheral wall of the limiting clamping plate, the clamping groove penetrates through two end faces of the limiting clamping plate, and the smooth section is slidably clamped in the clamping groove. Due to the design of the clamping groove, the installation between the limiting clamping plate and the bolt is more convenient.

In the above-mentioned coupling assembling, the flange is the annular, the groove width of draw-in groove is less than flange's external diameter. Through the arrangement, the bolt can be clamped into the clamping groove of the baffle plate, and the limiting flange above the thread section can not penetrate through the clamping groove.

In the above-mentioned connection assembly, the groove width of the clamping groove is slightly larger than or equal to the outer diameter of the smooth section. Through foretell setting, the card of the spacing cardboard of being convenient for and the bolt is established, and assurance stability that simultaneously also can furthest for spacing cardboard is difficult for coming off from the bolt.

In the above-mentioned connecting assembly, the clamping groove is U-shaped. The groove bottom of the U-shaped groove is arc-shaped and can be matched with the outer surface of the rod part of the bolt.

In the above-mentioned coupling assembly, the border of spacing cardboard still has the annular turn-ups of turning over outward and turning over formation, elastic element is the spring, the spring housing is established on smooth section and one end is supported and is leaned on with the head of bolt, the other end embedding annular turn-ups in with spacing cardboard supports and leans on. Through the arrangement of the annular flanging, the spring can be limited in the annular flanging and cannot slide out.

Compared with the prior art, this coupling assembling has following advantage: the produced pressure of bolt-up separates with the locking force of car light, lets the bolt compress elastic element at the in-process of locking to elastic element's elasticity is as the locking force of car light, can effectually prevent the deformation of automobile body panel beating and car light, lets the better state that accords with the design of installation of car light, guarantees the quality of assembly.
