[0025] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope protected by the present utility model.

[0026] In Figure 3 it can be found that the male and female fasteners in the present utility model are composed of a male fastener 1 and a female fastener 2, and the male fastener 1 is mutually clamped with the female fastener 2 by passing through the female fastener 2.

[0027] In Figure 2 it is the structural morphology of the male fastener 1. It can be found that the male fastener 1 includes a male fastener base 11 and a male fastener lock 12. The male fastener lock 12 includes at least one locking wing 121 and a male fastener lock post 122. The locking wing 121 is arranged on the outer surface of the male fastener lock post 122. The locking wing 121 realizes the male fastener lock 12 fixedly connected to the male fastener base 11, and a gap is formed between the male fastener lock post 122 and the male fastener base 11. In the present utility model, by forming a gap between the male fastener lock post 122 and the male fastener base 11, the gap can serve as a point of action. Acting on the gap with a tool and applying an outward force can realize the separation of the male and female fasteners.

[0028] In Figure 4 during the separation process of the male and female fasteners, in order to improve the uniform stress of the male fastener base and thus avoid damage and deformation of the male fastener. Therefore, there are 4 locking wings 121, and the distances between adjacent locking wings 121 are equal, and they are arranged around the outer surface of the male fastener lock post 122. The 4 locking wings ensure the stable connection between the male fastener lock and the male fastener base, thus avoiding damage to the male fastener due to poor connection stability during the separation process of the male and female fasteners. In Figure 1 it, the female fastener 2 includes a female fastener base 21 and a female fastener lock 22, and the female fastener base 21 and the female fastener lock 22 are fixedly connected; a groove 211 is provided on the surface of the female fastener base 21 opposite to the female fastener lock 22. The groove 211, the gap between adjacent locking wings 121, and the gap formed between the male fastener lock post 122 and the male fastener base 11 are on the same straight line. When the male fastener base and the female fastener base are closely attached, the design of the groove reserves an operation space for the separation of the male and female fasteners. A distance is also set between adjacent locking wings. By having the groove, the gap between adjacent locking wings, and the gap formed between the male fastener lock post and the male fastener base on the same straight line, it is beneficial to achieve uniform stress on the male fastener base and avoid damage to the male and female fasteners on the basis of realizing the separation of the male and female fasteners.

Those skilled in the art should understand that the shape of the locking fin can be designed according to experience. In this case, the shape of the locking fin can be a columnar body connected to a wedge-shaped block. The columnar body can enhance the connection strength between the locking fin and the male buckle seat, and the wedge-shaped block is conducive to engaging with the female buckle.

[0030] The male buckle lock 12 further includes a fixing pin 123 which is arranged on the male buckle lock column 122 at the opposite end to the male buckle seat 11; a fixing groove is provided inside the fixing pin 123; a protrusion matching the shape of the fixing groove is provided on the inner wall of the female buckle lock 22 at the opposite end to the female buckle seat 21, enabling the female buckle to move flexibly along the length direction of the fixing pin 123 in the fixing groove. In the present utility model, when the male buckle enters the female buckle through the through hole and before engaging the male and female buckles, the protrusion on the inner wall of the female buckle lock can move flexibly along the length direction of the fixing pin in the fixing groove. When engaging the male and female buckles, when the male buckle seat and the female buckle seat approach each other, the protrusion on the inner wall of the female buckle lock is engaged at the connection between the male buckle lock column and the fixing pin, and the wall of the female buckle lock realizes the engaging connection of the male and female buckles in an outwardly expanding manner, also realizing the fixing of the male and female buckles to the accessories on the vehicle body.

[0031] Finally, a through hole 212 is also provided at the center of the female buckle seat 21. The through hole is used as a channel for realizing the engagement and separation of the male buckle and the female buckle.
