As shown in fig. 1 and 3, further, the housing 100 in the present embodiment includes: back plate 120 and flange 130. The back plate 120 may be a flat plate, and is generally square, the flange 130 is enclosed on the front surface of the back plate 120, and the flange 130 may be provided with a plurality of blocks, or may be a block, which surrounds and encloses an inner cavity along the front surface of the back plate 120, and the film sticking cavity 110 is located in the area enclosed by the flange 130. The membrane limiting connection portion 200 is located outside the area surrounded by the flange 130, and is disposed on the front surface of the back plate 120. In the length direction, the flange 130 facing one end of the membrane limiting connection portion 200 is separated at intervals and forms a side opening 131, and when the screen membrane 500 is disposed on the housing 100, the protruding section 532 of the positioning membrane layer 530 protrudes from the side opening 131 and is sleeved with the membrane limiting connection portion 200. In the length direction, a diaphragm inlet and outlet 132 is formed on a flange 130 at the end opposite to the side opening 131, the diaphragm inlet and outlet 132 is communicated with the film pasting cavity 110, the diaphragm inlet and outlet 132 is in a hole structure, and the upper, lower, left and right sides of the diaphragm inlet and outlet 132 are provided with inner walls. The membrane inlet and outlet 132 and the membrane limiting connection part 200 are respectively positioned at two ends of the shell 100 in the length direction, the screen membrane 500 is inserted into the inner cavity of the shell 100 through the membrane inlet and outlet 132, so that the positioning membrane layer 530 is connected to the membrane limiting connection part 200 at the other end for limiting and fixing, and the dust collection release membrane layer 510 is positioned at the outer side of the membrane inlet and outlet 132, thereby being convenient for a user to draw out the dust collection release membrane layer 510 along the length direction.

The inner walls of the left and right sides of the membrane inlet and outlet 132 are used for positioning the width direction, so that the protective film 520 does not need to be limited in size, and the protective film 520 with different lengths and widths can be designed according to requirements to form different types of protective films, because the same mobile phone 10 screen has different schemes and processes with different sizes due to individuation requirements, for example, screen areas covered by silk-screen edge toughened films, 3D protective films and the like are different, and the sizes of the protective film 520 are different.

In addition, the width direction of the screen film 500 is limited by the width direction of the film inlet and outlet 132, and the simultaneous limitation of the length direction and the width direction by the film limiting connection part 200 can be avoided, so that the film limiting connection part 200 limits the length direction only, and then the connecting hole on the convex section 532 matched with the film limiting connection part can be slightly larger in the width direction, so that the screen film 500 can not move in the length direction while the connecting hole is sleeved into the film limiting connection part 200, and a better limiting effect is realized.

As shown in fig. 1, 6 and 8, further, the dust-absorbing release film 510 is abutted against the top inner wall of the membrane inlet 132 under the elastic force of the elastic member 400. In a specific structure, in an initial state, after the screen film 500 is inserted into the film sticking cavity 110, the elastic member 400 is already in a compressed state, so that after the dust-absorbing release film 510 is pulled away, the elastic member 400 returns to press one end of the protective film 520 against the screen of the mobile phone 10. The dust-free film sticking device can be combined with the screen film 500 and sold together, and the screen film 500 is directly connected to the dust-free film sticking device in the selling process, so that the whole dust-free film sticking device is used as a protective shell of the screen film 500, and in the transportation process, the screen film 500 is pressed against the top inner wall (upper inner wall) of the film inlet and outlet 132 by the elastic piece 400, so that the screen film 500 cannot shake in the up-down direction, and a foam pad and the like do not need to be additionally placed for packaging, thereby saving the production cost; the device is not easy to damage in the transportation process, and the yield in the transportation process is also ensured.

As shown in fig. 1, 6 and 8, further, the elastic member 400 in the present embodiment is disposed on the front surface of the back plate 120 in an extending manner along the width direction, and in a specific process, a counter bore is formed in an inner cavity of the front surface of the back plate 120, and the elastic member 400 is adhered in the counter bore, so that the installation of the elastic member 400 is facilitated. And set up along width direction, can make the elastic component 400 in the in-process of resilience promotion screen membrane 500, protection film layer 520 can even receive thrust in length direction's one end to guarantee that protection film layer 520 can bond simultaneously when bonding on the screen of cell-phone 10, effectively prevent the production of bonding bubble, the pad pasting effect is better.

Further, the elastic member 400 in this embodiment is a sponge strip. The sponge strip can generate softer elasticity, the compression thickness is also large, and the film pasting effect is better in the rebound pushing process. The elastic piece 400 can also adopt EVA elastic strips (foam strips), silica gel strips (rubber strips) or elastic plastic strips, and can also realize rebound pushing effect; in addition, the combination of the spring and the push plate can be adopted.

Further, the back plate 120 in this embodiment is a solid plate body with no hollow area on the surface. The use of a solid plate body allows for a design without a window in the middle, thereby preventing the user from pressing directly into the inner protective film 520 by careless manipulation. It is easily understood that decorative grooves, openings, etc. may be formed in the back plate 120, and that no erroneous operation is caused even if the opening is small.

As shown in fig. 1 and 3, further, the terminal limiter 300 in this embodiment specifically includes: support boss 310 and side support post 320. The supporting boss 310 is arranged on the front surface of the shell 100, the side supporting columns 320 are arranged on the supporting boss 310 along the thickness direction, a limiting step 330 is formed between the inner side surface of the side supporting columns 320 and the front surface of the supporting boss 310, the limiting steps 330 at different positions enclose an inner cavity of the limiting mobile phone 10, and the screen edge of the mobile phone 10 abuts against the limiting step 330. In a specific structure, the supporting boss 310 protrudes from the front surface of the back plate 120 by a certain height, so that the screen film 500 can be located in an area surrounded by the supporting bosses 310, and the area and the inner cavity surrounded by the limiting step 330 form the film sticking cavity 110 together. The side support columns 320 extend in the thickness direction by a certain height, and the support bosses 310 and the side support columns 320 are disposed on the inner wall of the flange 130, thereby enhancing the structural strength of the terminal stopper 300. The front edge of the screen of the mobile phone 10 abuts against the upper surface of the supporting boss 310, and the side edge of the mobile phone 10 abuts against the inner side surface of the side supporting column 320, so that the mobile phone 10 can be stably limited in the film sticking cavity 110.

In addition, according to different hole opening requirements, the terminal limiting member 300 on some sides may only include the side supporting columns 320, and the side surfaces of the side supporting columns 320 abut against the side edges of the mobile phone 10 to limit the mobile phone 10.
