[0023] The technical solutions in the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 5 As shown, a pull tab includes a pull tab body 1, an injection molded part 2, and an inlay 3. One end of the pull tab body 1 is provided with a through hole 11, and the other end of the pull tab body 1 is provided with a fixing hole 12. The injection molded part 2 is provided with a fixing column adapted to the fixing hole 12. The injection molded part 2 is fixedly connected to the pull tab body 1. The injection molded part 2 is provided with at least one through hole 21. The inlay 3 is arranged in the injection molded part 2, and the inlay 3 is located at the position of the through hole 21. The inlay 3 can be displayed through the through hole 21, thereby decorating the pull tab to increase the aesthetics of the pull tab. Specifically, the pull tab body 1, the inlay 3, and the injection molded part 2 are integrally injection molded.

[0025] The embedded component 3 is a sheet structure or a mesh structure. The material of the embedded component 3 is any one of aluminum alloy material, stainless steel material, carbon fiber material, graphene material, reflective material, colorful material, temperature-variable material, light-variable material and luminous material. Among them, reflective material, also known as retro-reflective material or retro-reflective material, is based on the principle of implanting a high-refractive index glass bead or micro-prism structure on the surface of the corresponding material to reflect the light back to the light source along the original path, thereby forming a retro-reflection phenomenon; colorful material is a layer or multiple layers of polymer material coated on a transparent substrate, and the difference in thickness and refractive index of these polymer materials is used to make the light interfere and refract when passing through the colorful material, thereby producing a rainbow-like effect; temperature-variable material is a material that changes color with temperature changes. Its basic principle is to use thermochromic microcapsules. These microcapsules contain thermosensitive pigments. These pigments will change color when the temperature changes. The color change process of temperature-variable materials is reversible, that is, when the temperature returns to a certain range, the color will return to its original state; light-variable materials use the principle of photochromic change. By absorbing ultraviolet rays and converting them into energy, the material undergoes molecular structure changes under sunlight or ultraviolet rays, thereby producing color changes. When the sunlight and ultraviolet rays are lost, the material will immediately return to its original color. This change is mainly based on the microcapsules encapsulating ultraviolet-sensitive color-changing materials. When ultraviolet rays are irradiated on the microcapsules, the color-changing materials undergo structural changes, causing the color to change. Luminous materials usually achieve the luminous effect by adding luminous substances such as fluorescent powder or phosphorescent powder. These luminous substances absorb light energy during the day or in well-lit conditions, and then release the absorbed energy in a dark or dimly lit environment, emitting bright fluorescence or phosphorescence.

[0026] The embedded component 3 may be hard or soft and may be bent to a certain extent.
