The whole device has a simple structure, occupies a small space, and has a lower cost, which solves the problems of high production cost, large volume, and inconvenient transportation of the film sticking device.

[0026] Specifically, the connecting component 5 includes a spring 502 and a connecting plate 501; a plurality of springs 502 are arranged in a rectangular array on the upper surface of the bottom plate 1; the connecting plate 501 is arranged above the bottom plate 1; wherein the connecting plate 501 is elastically connected to the bottom plate 1 through the spring 502, and the two ends of the spring 502 are fixedly connected to the bottom plate 1 and the connecting plate 501 respectively, and the elastic coefficient of the spring 502 is selected and used by the technicians of this profession according to the actual situation; wherein the connecting plate 501 and the bottom plate 1 form an adjustment cavity. The utility model arranges the spring 502 and the connecting plate 501, and utilizes the spring 502 to make the height of the connecting plate 501 adjustable, thereby adjusting the height of the mobile component 6, and the height of the mobile phone placed in the mobile component 6 is also adjusted, and is suitable for mobile phone films of different thicknesses.

[0027] Furthermore, the moving component 6 includes a slide rail 605, a moving plate 601, a placement groove 603, a spring piece 602 and a through hole 604; the two slide rails 605 are symmetrically embedded in the connecting plate 501; the moving plate 601 is fixed to the moving end of the slide rail 605; wherein the moving plate 601 is slidably connected to the connecting plate 501 through the slide rail 605, and a gap is left between the moving plate 601 and the connecting plate 501; the placement groove 603 is opened on the placement side of the moving plate 601; the two spring pieces 602 are symmetrically arranged in the placement groove 603; the through hole 604 is opened on the moving plate 601 in the placement groove 603. The utility model provides a spring piece 602, and when the mobile phone is placed in the placement slot 603, its side will squeeze the spring piece 602, until the mobile phone is completely placed in the placement slot 603, the squeezed spring piece 602 presses against the side of the mobile phone, and the two spring pieces 602 cooperate to position the mobile phone in the placement slot 603. The mobile phone can be positioned by directly placing it, and the structure is simple and the operation is convenient.

[0028] Furthermore, the spring pieces 602 are designed with an arc-shaped structure, and the protruding ends of the two spring pieces 602 face each other. When the mobile phone is put in, the side of the mobile phone contacts the arc side of the spring piece 602, reducing the resistance of the mobile phone, making the spring piece 602 easier to be squeezed and the mobile phone easier to put in and position.

[0029] It is worth noting that the moving length of the moving plate 601 matches the distance from the head end of the connecting plate 501 to the entry end of the pressing roller 4.

[0030] Working principle: When using the device of the utility model, the bottom plate 1 is placed on the table, the suction cup 2 is fixed on the table, the moving plate 601 is moved to the front end of the connecting plate 501, the mobile phone to be filmed is placed in the placement groove 603, the protective film is covered on the mobile phone screen, and the moving plate 601 and the mobile phone are moved from the front end of the connecting plate 501 to the rear end thereof. The mobile phone at the rear end of the moving plate 601 first contacts the curved surface of the pressure roller 4 at the entrance end and is squeezed downward. Under the action of the spring 502, the moving plate 601, the mobile phone and the connecting plate 501 are pressed downward. The mobile phone is moved downward until the protective film contacts the pressure roller 4. At this time, the spring 502 provides an upward elastic force, causing the pressure roller 4 to squeeze the protective film. As the shift plate 601 moves, the pressure roller 4 rolls and squeezes the protective film, thereby sticking the protective film to the mobile phone screen. When the front end of the shift plate 601 moves to the end of the connecting plate 501, the mobile phone completely passes through the pressure roller 4, and the through hole 604 is exposed. The mobile phone is pushed upward from the bottom to be pushed out of the placement slot 603 with a finger through the through hole 604, and the mobile phone with the film is removed.
