The projection 601 rests against the side wall of the touch screen phone 7, which is beneficial for locating the position of the touchscreen phone 7 in the film shell 1 and avoiding the protective film 9 from being tilted on the touchscreen phone 7.

[0056] There are a plurality of projections 601, with an receding groove 602 formed between two adjacent projections 601, a functional key located on the side wall of the touchscreen phone 7 is accommodated in the receding groove 602. In this embodiment, there is a planar height difference between the projections 601 and the blocking wall 6, two adjacent projections 601 and the blocking wall 6 are enclosed to form the receding groove 602. By providing the receding groove 602, it is possible to avoid structural interference between the function keys of the touchscreen phone 7 and the blocking wall 6. The receding groove 602 accommodating the function keys is conducive to avoiding scratches and abrasions on the side walls of the touchscreen phone 7.

[0057] In this embodiment, the protective film 9 includes a protective film substrate 901, an adhesive layer 902 provided on the protective film substrate 901. The release film 8 covers the adhesive layer 902. The touchscreen phone 7 carries the release film 8 to position the protective film 9 on the screen of the touchscreen phone 7. The release film 8 has a pulling portion 803, the pulling portion 803 moves away from the film shell 1 to bring the release film 8 out, so that the protective film substrate 901 is adhered to the screen through the adhesive layer 902. The release film 8 covers the adhesive layer 902 of the protective film 9 and serves to protect the adhesive layer 902 from contamination or damage before use. The user positions the release film 8 on the screen by means of the positioning bump 305. As the release film 8 is adhered to the protective film, the protective film 9 is positioned on the screen with the aid of the release film 8. This ensures that the protective film 9 accurately covers the screen during installation and avoids offsetting or misalignment. The adhesive layer 902 is made of OCA, PET substrate, and silicone material, which has good adhesion and bonding properties. OCA (Optical Clear Adhesive) ensures high transparency and good optical performance between the protective film 9 and the screen, making the screen display clearly. The PET base material provides a certain strength and stability, preventing the protective film 9 from being deformed or damaged during use. Silicone material, on the other hand, increases the flexibility and cushioning performance of the adhesive layer 902, which is better adapt to the curved surface and curvature of the screen, also absorbs impacts to a certain extent, protecting the screen from external damage.

[0058] Compared with the existing technology, the protective film substrate 901 is provided with a locating film on one side away from the adhesive layer 902, the locating film is provided with a locating hole for mating with the positioning post of the sticking assembly. The protective film of the present invention saves the use of the locating film and effectively reduces the producing cost. The film shell 1 is molded based on the design of this protective film 9.
