Therefore, the fastener 1 of the utility model has a better bonding effect while meeting the bending characteristics of various adaptive installations, thereby ensuring the assembly quality of the product.

[0025] In this embodiment, please refer to Figure 1 The shape of the deformation notch 2 is a trapezoid or an arc. When the deformation notch 2 is a trapezoid or an arc, the notch transition of the deformation notch 2 is smoother, so that the bending portion 3 can be deformed more naturally when bent, and the adaptability is better.

[0026] In this embodiment, please refer to Figure 1 , each of the deformation notches 2 is evenly spaced and arranged in the length direction of the body of the fastener 1. The evenly spaced arrangement of the deformation notches can ensure that the deformation uniformity of the fastener 1 remains consistent when it is bent in one direction, so that the overall bending performance of the fastener 1 is better and the assembly adaptability is better.

[0028] In this embodiment, the tackifying protrusion 5 is provided with an arc transition, and the surface fillet of the tackifying protrusion 5 is 2 mm. The arc transition can make the contact effect between the fastener 1 and the foam body more uniform.

[0029] In this embodiment, the distance between two adjacent deformation notches 2 is 20 mm.

[0030] In this embodiment, the tackifying protrusion 5 is integrally formed and connected with the buckle element 4. The tackifying protrusion 5 is integrally formed and connected with the buckle element 4, and the matching stability is better.

Optionally, the covering layer 7 can be made of soft glue or silicone. The coating layer 7 is provided with iron powder or magnetic powder. The coating layer 7 is provided with iron powder or magnetic powder so that when the fastener 1 is embedded in the mold of the foamed plastic, it is only necessary to pre-install a magnet block at the position where the fastener 1 is fixed on the mold. The iron powder or magnetic powder in the coating layer 7 will generate attraction with the mold, and the fastener will be stably fixed on the mold through the magnetic force of the magnet, avoiding the fastener 1 from becoming loose during injection molding and affecting the fastener quality. When the flocking layer 8, non-woven fabric layer, hair curling layer or mesh layer on the back of the fastener 1 is embedded with the foam, the flocking, non-woven fabric, hair curling or mesh body thereon is immersed in the foam, which increases the contact area when the foam is bonded with the fastener 1, making the foam-bonded fastener more stable.
