In the embodiment, the buckle head end 11 is bullet-shaped, has a groove 113 at the root of the buckle head end 11, and the bottom of the groove 113 is connected with the buckle head end 11 through a tapered surface 113a. In the embodiment, the buckle head end 11 is hollowed out, so that the outer circumferential surface of the buckle head end 11 has a plurality of elastic deformation zones; specifically, the hollowing comprises a plurality of through channels 15 arranged in the buckle head end 11, the through channels 15 are communicated with the outer circumferential surface of the buckle head end 11, and the buckle head end 11 is divided into a plurality of elastic deformation zones 11a. In addition, a plurality of first deformation channels 13 and second deformation channels 14 are arranged in parallel with the axis of the buckle head end 11; the first deformation channels 13 and the second deformation channels 14 both penetrate into the elastic deformation zones 11a, and the first deformation channels 13 and the second deformation channels 14 are both communicated with the through channels 15. In the embodiment, the first deformation channels 13 and the second deformation channels 14 are preferably polygonal structures. Thus, the first deformation channels 13, the second deformation channels 14 and the through channels 15 form a honeycomb-like structure on the buckle head end 11, which takes into account the elasticity and mechanical strength, and under the premise of ensuring sufficient holding force, the buckle is relatively easy to install and insert into the metal hole, and in the process of repeated insertion and extraction, the mechanical performance attenuation is small, and after repeated insertion and extraction, the buckle can still be tightly pressed against the hole of the vehicle body, so that the sealing body can be tightly pressed at the sealing position, thereby ensuring good sealing performance.

[0029] Of course, the buckle head end 11 further comprises a support column 16 arranged at the center thereof, the first deformation channels 13, the second deformation channels 14 and the through channels 15 are symmetrically centered on the support column 16, preferably two first deformation channels 13 and two second deformation channels 14 are arranged, and the cross-sectional area of the first deformation channels 13 is larger than that of the second deformation channels 14. The support column 16 provides support for the elastic deformation zones 11a, thereby maintaining the reliable use strength thereof. It should be noted that the current buckle structure is often a structure in which the lower edge of the buckle is separated from the main body, and compared with the current buckle structure, the lower edge of the elastic deformation zone 11a formed by the first deformation channels 13, the second deformation channels 14 and the through channels 15 of the buckle head end of the embodiment is integrally connected with the buckle head end, and under the action of the hexagonal first deformation channels 13 and the second deformation channels 14, the elastic deformation zone 11a is more easily to maintain excellent elastic recovery ability after extrusion deformation, thereby having long-term holding force.

Specifically, the plastic body 10 and the sealing body 20 are integrally injection molded; the plastic body 10 is first injection molded, and then the plastic body 10 is secondarily injection molded by using a flexible material to obtain the sealing body 20, and part of the extension section 17 is covered in the sealing body 20, so that reliable connection of the two is realized. Preferably, the material of the plastic body 10 is a thermoplastic material, such as POM, PA, etc., and the material of the sealing body is preferably TPE. The sealing body 20 is designed by using TPE soft glue, so that after the buckle is installed into the hole of the vehicle body, the TPE soft glue is tightly matched with the edge of the hole of the vehicle body by strong force, so that omnidirectional sealing is realized, and good sealing performance can be maintained after repeated plugging and unplugging and environmental changes such as high and low temperatures.
