Thus, a feature to which "first" or "second" is qualified may explicitly or implicitly include one or more features. In the description of the invention, "plurality" means two or more unless otherwise specified.

[0021] 1 to 6, a film sticking device 100 provided in an embodiment of the present invention will be described. The film sticking device 100 includes a case 10, a cover 20, and a film assembly 40. The case 10 includes a positioning frame 13 for positioning the mobile phone 200 and a fixed position 101 for accommodating the protective case 300. The positioning frame 13 is partially positioned within the fixed position 101, and includes a first position avoidance area 102 for avoiding one side of the protective case 300 and a second position avoidance area 103 for avoiding the other side of the protective case 300. The cover 20 is used to close the case 10 and is movably connected to the case 10. The film assembly 40 is used to stick a film on the surface of the mobile phone 200 and is connected to the cover 20.

[0022] The first position avoidance area 102 and the second position avoidance area 103 may be cutouts or the like in the positioning frame 13, and the positioning frame 13 is not a completely closed frame shape. The first position avoidance area 102 and the second position avoidance area 103 can respectively accommodate adjacent two sides of the protective case 300, so that the protective case 300 can be partially inserted into the positioning frame 13, reducing the area of ​​the case 10 and utilizing the space within the case 10 to accommodate the protective case 300.

[0023] The cover body 20 and the case body 10 may be detachably connected, for example, by engaging, screwing, or other methods, or by a hinge, which makes it convenient to open the cover body 20 so as to remove the protective case 300 inside the cover body 20 and place the mobile phone 200 that needs to have a film attached into the positioning frame 13.

[0024] The positioning frame 13 surrounds a positioning area 130 that matches the size of the mobile phone 200 .

[0025] In the embodiment of the present invention, the positioning frame 13 is adopted to position the mobile phone 200, thereby aligning it with the film assembly 40 to prevent the mobile phone 200 from moving during film application; the fixed position 101 is adopted to package the protective case 300 and the film application device 100 together, thereby easily storing the protective case 300, thereby reducing the amount of packaging and making it convenient to store and transport the protective case 300; the fixed position 101 partially overlaps the area where the positioning frame 13 is located, thereby utilizing the area where the positioning frame 13 is located to store the protective case 300, which helps to reduce the size of the case 10.

[0026] 2 to 6, in one embodiment of the present invention, the case 10 includes a bottom plate 11 and a first surrounding frame 12, and the cover 20 includes a cover plate 21 and a second surrounding frame 22 for engaging with the first surrounding frame 12. This improves the structural strength of the edges of the bottom plate 11 and the cover plate 21 and prevents deformation, which is advantageous in increasing stability when the case 10 and the cover 20 are engaged with each other.

[0027] 2 to 6, in one embodiment of the present invention, a support frame 14 is provided in the case 10 to support and position the back of the mobile phone 200, the support frame 14 is located inside the positioning frame 13 and the fixed position 101, and the height of the support frame 14 is smaller than the height of the positioning frame 13. The height of the support frame 14 is the size of the support frame 14 along the depth direction Z of the case 10, the height of the positioning frame 13 is the size of the positioning frame 13 along the depth direction Z of the case 10, the bottom of the support frame 14 is approximately flat with the bottom of the positioning frame 13, and the support frame 14 is located in the area where the positioning frame 13 and the fixed position 101 overlap. In this way, the mobile phone 200 is supported by the support frame 14, the height of the mobile phone 200 within the positioning frame 13 can be controlled, interference caused by protrusions such as the camera on the back of the mobile phone 200 can be avoided, and it is advantageous to improve the structural strength of the case 10 and prevent deformation of the case 10 from affecting the application of the film.
