[0002] Smart products such as mobile phones and tablets can interact through the screen to enrich the user experience. However, frequent interactions through the screen can easily damage the screen and cause scratches if not protected, affecting the visual effect of the screen. Therefore, users usually put a protective film on the screen of smart devices to protect the screen and extend the use time of the screen. However, when applying the film, you need to tear off a corner of the release film at the bottom first, then stick the torn part of the protective film on the screen, and then tear off the release film while completely sticking the protective film on the screen. Due to the lack of reference when applying the protective film, it is difficult for users to confirm whether the positioning of the applied protective film is accurate before applying it, which can easily cause the applied protective film to shift, and the protective film needs to be torn off and adjusted later. Readjustment may also cause the protective film to be invalid, which is inconvenient to use. Utility Model Content

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] Embodiment 1: A protective film for a screen of a smart device, comprising a protective film body 1 and an upper release film 2 and a lower release film 3 respectively arranged on the front and back sides of the protective film body, wherein the upper surfaces of the left and right edges of the upper release film 2 are provided with positioning stickers 4, wherein the positioning stickers 4 include inner positioning stickers 41 and outer positioning stickers 42, wherein the outer positioning stickers 41 are located outside the upper release film 2, wherein the inner positioning stickers 41 and the outer positioning stickers 42 are provided with positioning references 5 corresponding to each other, wherein when in use, the protective film body 1 is first placed on the screen to be pasted, and then the outer positioning stickers 4 are placed on the screen to be pasted. 2 is pasted on the side of the smart device where the screen is to be pasted, and then the outer positioning sticker 42 is separated from the inner positioning sticker 41, so that when the lower release film 3 is torn off and the protective film body 1 is pasted, the outer positioning sticker 42 and the inner positioning sticker 41 are used as references 5 for positioning to improve the accuracy of film pasting and prevent crooked pasting. After the protective film body 1 is pasted, the upper release film is torn off and the inner positioning sticker can be torn off at the same time. The outer positioning sticker 42 can be pasted by setting a pressure-sensitive adhesive layer 7. After the pressure-sensitive adhesive is peeled off, it is not easy to contaminate the adherend, so that the outer positioning sticker 42 can be torn off and cleaned.

[0020] Furthermore, the positioning reference 5 can be squares of three colors: red, yellow, and blue. The squares on the inner positioning sticker 41 and the outer positioning sticker 42 are arranged in a circular pattern in the order of red, yellow, and blue. The squares on the inner positioning sticker 41 are the same color as the squares on the adjacent outer positioning sticker 42. When the inner positioning sticker 41 and the outer positioning sticker 42 are separated and the protective film body 1 is used for film application, the protective film can be positioned by matching the squares of the same color on the inner positioning sticker 41 and the outer positioning sticker 42 to prevent displacement during film application.
