[0002] Protective films can be divided into digital product protective films, car protective films, household protective films, food preservative protective films, etc. according to their uses. With the popularization of digital products such as mobile phones in China, protective films have gradually become a general term for screen protective films, and their functions in the field of screen protective films are also varied. From the earliest PP materials to today's popular AR materials, they are gradually being accepted by the majority of mobile phone users.

[0003] In response to consumer demand, mobile phone protective films in the prior art gradually develop into one-piece protective films. Such one-piece protective films can protect the mobile phone in a surrounding manner, and then the two sides of the protective film can be bonded to each other on the back of the mobile phone. When the one-piece protective film is used on the mobile phone for a long time, the two-side joints of the one-piece protective film are prone to warp up on the back of the mobile phone case, thereby causing the one-piece protective film to easily detach from the outside of the mobile phone case.

[0004] For this purpose, we propose a one-piece protective film. Utility Model Content

[0008] Furthermore, an oblique connecting piece is bonded and fixed between the outer body of the side fixing seat A and the side fixing seat B and the one-piece membrane.

[0009] Furthermore, the head of the column of the boss A and the boss B is integrally formed with a cone head, and the block of the cone head gradually shrinks upward from the head of the column of the boss A and the boss B; with the help of the cone head, the boss A and the boss B can be inserted and clamped in the fixed holes of the side seat A and the side seat B respectively.

[0010] Furthermore, the column diameters of the protruding columns A and B are the same as the hole diameters of the fixed holes; the fixed holes of the side fixed seats A and B can be respectively fitted with the protruding columns A and B.

[0011] Furthermore, the membrane body size of the tooth membrane is the same as the notch size of the tooth opening; the tooth membrane can be adapted and clamped at the tooth opening.

[0012] Furthermore, the membrane edge of the tooth membrane is bonded and fixed to the contact point of the one-piece membrane; after the tooth membrane is bonded and connected to the one-piece membrane, it is not easy to fall off from under the membrane strip.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model provides a connecting mechanism on both sides of the one-piece film, and the one-piece film can be bonded to the screen and the outside of the back shell of the mobile phone in a surrounding manner with the connecting mechanism. The connecting mechanism enables the two sides of the one-piece film to be connected by snapping at the back of the collection back shell. The one-piece film can be connected to the outside of the mobile phone shell with high firmness by means of the connecting mechanism, so that the one-piece film is not easy to fall off from the mobile phone shell, thereby ensuring the firmness of the one-piece film outside the mobile phone shell.
