[0002] Screen protector applicators are usually accessories included with the screen protector itself, typically a positioning frame or component, used to help users position the phone and screen protector correctly. Currently, flexible screen protectors on the market are usually applied using an applicator and a squeegee. First, the applicator is used to position the phone and screen protector. Then, the release liner on the screen protector is peeled off. The squeegee is used to stick the screen protector onto the phone, and finally, the positioning film on the screen protector is removed.

[0003] While this screen protector applicator can complete the screen protector application process, it also has the following drawbacks: 1. Due to the special characteristics of curved screen phones, it is difficult to effectively adhere the left and right sides of the screen protector to the left and right sides of the curved screen, which can easily lead to peeling edges. In addition, when using a squeegee to scrape the screen protector, it is easy to apply uneven force, which can affect the application effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a curved screen mobile phone screen protector applicator. This applicator is used for applying screen protectors to curved screens, and is simple and convenient to operate with good screen protector application results.

[0018] The beneficial effects of this invention are as follows: This invention includes a film-pressing slider. During the movement of the film-pressing slider, the first and second pressure rollers can roll and press the front surface and left and right edges of the screen protector, ensuring a tight fit between the screen protector and the curved screen phone. This solves the problem of edge lifting that often occurs when applying screen protectors to curved screen phones. Simultaneously, because the movement path of the film-pressing slider is fixed, the pressure applied to the screen protector by the first and second pressure rollers is also fixed. This ensures uniform force application by the first pressure roller, effectively preventing scratches, damage, and wrinkles on the screen protector due to uneven force, resulting in a superior application effect. Furthermore, the size of the phone placement area can be adjusted by the up-and-down movement of the adjustable positioning component, making it suitable for applying screen protectors to phones of different sizes, thus exhibiting strong applicability.
