[0040] Please refer to Figure 1-7 The first object of the utility model is to provide a film sticking tool 100, which is applied to the above-mentioned film sticking method, including a main body 110, a front positioning member 130, a rear positioning member 140 and a pressing component 150. The main body 110 includes a accommodating cavity 111, a first end 112 and a second end 113, wherein the accommodating cavity 111 is used to accommodate the electronic device; the front positioning member 130 is connected to the main body 110 and is disposed at the first end 112; the rear positioning member 140 is connected to the main body 110 and is disposed at the second end 113; the pressing assembly 150 includes a sliding cover 151, a scraper 152 and an elastic member 153, wherein the sliding cover 151 is slidably connected to the main body 110, and the scraper 152 is rotatably connected to the sliding cover 151, the scraper 152 is inclined relative to the sliding cover 151 and the scraper 152 gradually moves away from the first end 112 in the direction of the sliding cover 151 toward the main body 110, and the elastic member 153 is disposed between the sliding cover 151 and the scraper 152 to adaptively adjust the height position of the scraper 152. Exemplarily, the sliding cover 151 includes an upper cover 1511 and a lower cover 1512, the upper cover 1511 is fixedly mounted on the lower cover 1512, the lower cover 1512 is provided with an oblique groove 1512A, the upper cover 1511 and the lower cover 1512 are enclosed to form an accommodating space, the scraper 152 includes a rotating part 1521 and a scraper part 1522, the rotating part 1521 is rotatably mounted on the lower cover 1512, the rotating part 1521 and a part of the scraper part 1522 are located in the accommodating space, the scraper part 1522 is exposed to the lower cover 1512 through the oblique groove 1512A, and the scraper 152 can be rotated within the range of the oblique groove 1512A, that is, the oblique groove 1512A also has the function of limiting the rotation range of the scraper 152. It is understandable that the front end of the scraper portion 1522 can also be provided with an elastic pad made of elastic material (not shown in the figure), which is not only conducive to protecting the film 220 assembly and preventing the film assembly 200 from generating creases or knife lines, but also can increase the friction between the scraper 152 and the film assembly 200, increase the squeezing effect of the scraper 152, and further avoid the existence of bubbles between the film and the electronic device. In this embodiment, the elastic member 153 is a torsion spring, and the elastic member 153 is nested in the rotating portion 1521, and one end of the elastic member 153 abuts against the lower cover 1512, and the other end abuts against the scraper portion 1522. It is understandable that when applying the film, the scraper 152 squeezes the film assembly 200, and the elastic member 153 is in a stressed state.

[0041] Please refer to Figure 1 , Figure 2 , Figure 3 Two positioning parts 114 are also provided in the accommodating cavity 111. A positioning groove 1141 is formed on the positioning part 114. A positioning block (not shown in the figure) is installed in the positioning groove 1141. In this embodiment, two positioning parts 114 are provided, which are respectively arranged near the first end 112 and the second end 113. Their function is to position and fix the mobile phone when applying the film. It can be understood that two positioning blocks are also provided. The positioning blocks are made of elastic materials such as silicone, which is conducive to protecting the mobile phone and preventing the mobile phone from being scratched and damaged. The width of the positioning block can be freely selected. The user can install a positioning block of an appropriate size according to the specific size of the mobile phone, which is conducive to improving the applicability of the film applying artifact 100.

[0042] Please refer to Figure 5 , Figure 6 , Figure 7 The film-applying tool 100 of the present application sets the scraper 152 at an angle relative to the sliding cover 151, and the angle of the scraper 152 is adjustable and can rotate within a certain angle range. The scraper 152 is used in conjunction with a spring so that the angle of the scraper 152 can be adaptively adjusted according to the thickness of the electronic device and the diaphragm, thereby achieving the purpose of adjusting the height position of the scraper 152. Regardless of the type of device and diaphragm used, the film-applying tool 100 of the present application is applicable, and ensures that the scraper 152 fits tightly with the diaphragm and the electronic device, which is conducive to improving the tight fit between the diaphragm and the electronic device without generating gaps and bubbles.

[0043] Please refer to Figure 1 , Figure 2 , Figure 3 In this embodiment, the film-sticking artifact 100 of the present application cooperates with the diaphragm assembly 200 to implement the film-sticking of electronic devices. After the diaphragm assembly 200 is fixed to the film-sticking artifact 100, the protective film 220 is flipped 180° through the handle 223 and then torn off as a whole piece. At this time, the diaphragm assembly 200 is fully tightened by the film-sticking artifact 100, and no creases or cut lines will be generated due to bending, thereby avoiding subsequent impact on user use.

[0044] Please refer to Figure 5 , Figure 6 , Figure 7In one possible implementation, the angle β between the scraper 152 and the upper end surface of the slide cover 151 is in the range of [25°, 45°]. Exemplarily, the purpose of the inclined setting of the scraper 152 is to simulate the process of artificial film pasting, so that the scraper 152 is pushed forward in the film pasting direction, thereby squeezing out the air between the diaphragm assembly 200 and the electronic device, and no bubbles are produced, and the film pasting effect is good. It can be understood that the scraper 152 is inclined toward the sliding direction of the pressing assembly 150 on the main body 110, that is, the closer to the bottom of the accommodating cavity 111, the closer the scraper 152 is to the second end 113. In this embodiment, the scraper 152 can rotate within the range of 25° to 45°, and the height position of the front end of the scraper 152 is adjusted by rotating the scraper 152 to adapt to mobile phones of different thicknesses and diaphragms of different thicknesses.

[0045] Please refer to Figure 1 , Figure 2 , Figure 3 In a possible implementation, the slide cover 151 includes a mounting groove 1512B, and a boss 1512C extends from the mounting groove 1512B. The main body 110 also includes a slide groove 118 and an entrance groove 119 connected to the slide groove 118. The boss 1512C enters the slide groove 118 through the entrance groove 119, and the boss 1512C cooperates with the slide groove 118. Exemplarily, the slide groove 118 extends from the first end 112 to the second end 113. The slide groove 118 is provided with two, which are respectively provided on opposite sides of the main body 110. It can be understood that there are two bosses 1512C, which cooperate with the two slide grooves 118 respectively. The boss 1512C and the slide groove 118 have a guiding function, which can guide the pressing assembly 150 to slide along a predetermined track. It is helpful to ensure that the pressing assembly 150 will not slide up and down or left and right during the sliding process, and avoid uneven pressure applied by the pressing assembly 150 to the diaphragm assembly 200 during the film application process.

[0046] Please refer to Figure 5 , Figure 6 , Figure 7In a possible implementation, the pressing assembly 150 further includes a handle 154, which is rotatably connected to the sliding cover 151. Exemplarily, the function of the handle 154 is to facilitate the user to pull the pressing assembly 150 through the handle 154, the upper cover 1511 is provided with a rotation groove 1511A and a stopper 1511B, the stopper 1511B protrudes from the side of the rotation groove 1511A, the handle 154 is rotatably connected to the upper cover 1511 through the rotation groove 1511A, and the handle 154 is installed on the side away from the lower cover 1512. The function of the stopper 1511B is to limit the rotation range of the handle 154. Specifically, in this embodiment, the maximum angle that can be formed between the handle 154 and the upper cover 1511 is 90°. The setting of the stopper 1511B is conducive to ensuring that the pressing assembly 150 can only be pulled in one direction, and the handle 154 will not be rotated to the opposite direction, so that the user can pull the pressing assembly 150 from the opposite direction. In addition, the handle 154 can be provided with anti-slip convex patterns to increase the friction between the user's hand and the handle 154, so as to facilitate the user's operation.

[0047] Please refer to Figure 1 , Figure 2 , Figure 3 In a possible implementation, the main body 110 further includes a placement groove 115 connected to the accommodating cavity 111. The placement groove 115 is arranged near the first end 112. The accommodating cavity 111 has a placement area 116 for placing the electronic device. The ratio of the orthographic projection area of ​​the placement groove 115 to the orthographic projection area of ​​the placement area 116 is not less than 40%. Exemplarily, the placement groove 115 is used to accommodate the rear lens of the mobile phone. The reason for limiting the area ratio of the placement groove 115 to the placement area 116 is to ensure that the notch of the placement groove 115 is large enough to accommodate any mobile phone on the market, thereby improving the compatibility of the film-sticking artifact 100 of the present application. In this embodiment, the placement groove 115 is rectangular. Of course, in a specific application, the shape of the placement groove 115 is not limited thereto. For example, as an alternative, it can also be a trapezoid, a circle or other irregular shapes. Specifically, the ratio of the orthographic projection area of ​​the placement groove 115 to the orthographic projection area of ​​the placement region 116 may be 40%, or 45%, or 50%, or 55%, or 60%, and no excessive restrictions are imposed herein.

[0048] Please refer to Figure 1 , Figure 2 , Figure 3In a possible implementation, the main body 110 further includes a through slot 117 connected to the accommodating cavity 111, and the through slot 117 is arranged near the second end 113. Exemplarily, the function of the through slot 117 is that after the mobile phone film is applied, the user can insert a finger into the through slot 117 to take out the mobile phone. It can be understood that the size of the through slot 117 should be larger than the size of the finger so that the user's finger can be inserted. In this embodiment, the through slot 117 is circular. Of course, in a specific application, the shape of the through slot 117 is not limited thereto. For example, as an alternative, the shape of the through slot 117 can be set to an elliptical, rectangular, trapezoidal or other irregular shapes.

[0049] Please refer to Figure 1 , Figure 2 , Figure 3 In one possible implementation, the sliding cover 151 includes an anti-idiot groove 1513, and the front positioning member 130 is provided with an anti-idiot protrusion 131 that cooperates with the anti-idiot groove 1513. Exemplarily, in this embodiment, two anti-idiot grooves 1513 are provided, and the anti-idiot grooves 1513 are semicircular. It can be understood that the shape, number and shape of the anti-idiot protrusion 131 are the same as those of the anti-idiot groove 1513. Through the cooperation of the anti-idiot groove 1513 and the anti-idiot protrusion 131, the front positioning member 130 will not be installed upside down. If it is installed upside down, the pressing assembly 150 cannot be installed on the main body 110.
