[0061] Comparative analysis:

[0062] Comparing the technical solution of the present application with the prior art of a portable mobile phone display screen film device with patent number 2024211302269, the present technical solution provides a packaging shell for assisting mobile phone film application, mainly including a bottom plate 1, a positioning plate 3, a top cover 10 and a series of auxiliary components, such as a positioning insert 6, a mobile phone film sheet 7, a pull-out strip 8, etc. Through precise positioning, pressing and pasting, etc., the mobile phone film can be quickly and accurately pasted.

[0063] The comparative example provides a convenient mobile phone display screen film pasting device, including a placement shell, a protective cover, a glass plate, a fixing rod, a first shift block and a sponge block and other components. The film pasting is completed by fixing the mobile phone, cleaning the screen, pasting the mobile phone film and squeezing out bubbles.

[0064] The technical solution of the present application realizes accurate positioning of the mobile phone through the positioning groove 4 and the positioning block 5 on the positioning plate 3, ensuring the accurate alignment of the mobile phone film 7 with the mobile phone screen. This positioning method is simple, fast, and adaptable to mobile phones of different models. In contrast, the mobile phone is fixed by a clamp and an elastic member. Although the mobile phone can also be fixed, the positioning accuracy is relatively low, and the clamp position may need to be adjusted according to the mobile phone model, and the operation is relatively cumbersome.

[0065] This technical solution adopts the design of the pull-out strip 8, which is convenient for users to easily pull out the protective layer under the mobile phone film sheet 7, and then evenly apply force through the pressing groove 11 to make the mobile phone film sheet 7 fit tightly with the mobile phone screen. The whole process is smooth and simple, and can effectively avoid the generation of bubbles. In the comparative example, the mobile phone film is manually squeezed by the squeezing rod and the third dial block to remove bubbles. This method may require multiple operations, and uneven force application may result in poor film effect.

[0066] The bottom plate 1 and the top cover 10 of the technical solution are connected by hinges to form a compact whole, which is convenient for carrying and storage. All components required for film application are integrated in the packaging shell, and there is no need to carry additional cleaning cotton, hanging blocks and other tools. Although the comparative example also designs a carrying rod and buckle for easy carrying, the overall structure is relatively loose and contains multiple independent parts such as fixing rods, squeezing rods, etc., which may be easily lost or damaged during carrying and storage.

[0067] The bottom plate 1 and the top cover 10 of the technical solution are made of bamboo pulp material, which has good durability and degradability and meets environmental protection requirements. At the same time, technical features such as positioning indicators, dustproof sheets and exhaust holes are added to further improve the quality of the film and user experience.

[0068] In summary, this technical solution is a further research and development of the shortcomings of the comparative example, which shows remarkable creativity in positioning accuracy, film application process, portability and integration, material selection and environmental protection, and additional functions. Through precise positioning, smooth film application process, compact structure design, environmentally friendly material selection, and multiple additional functions, this technical solution provides a more convenient, efficient, and practical mobile phone film application auxiliary tool, which meets the user's high-quality demand for mobile phone film application.
