The bottom surface of the screen protector attaching device main body is formed with a holding space that matches the contour of the mobile phone and can cover the cell phone. The reinforced glass film is configured inside the area of the holding space with connection to the connector; a stopper is configured inside the area of the holding space; when the screen protector attaching device main body covers the cell phone, of the two relative ends of the reinforced glass film, one end contacts the screen of the cell phone, the other end is separated from the screen of the mobile phone by a gap due to the block of the stopper. ## Claims ### Claim 1 An improved cell phone screen protector attaching device equipped with a reinforced glass film, including a screen protector attaching device main body (1), a connector (2), and a reinforced glass film (3), a holding space (11) disposed in a bottom surface of the screen protector attaching device main body (1) for matching the shape of a mobile phone and covering the mobile phone, wherein the reinforced glass film (3) is arranged in the holding space (11) through a connector (2), a stopper (4) is provided in an area enclosed by the holding space (11); the connector (2) is connected to an upper surface of the reinforced glass film (3), and a lower surface of the reinforced glass film (3) is attached with a release film piece (5); when the screen protector attaching device main body (1) is covered on the mobile phone, one end of the reinforced glass film (3) is in contact with the mobile phone screen, and another end is blocked by the stopper (4) and there is a gap between the mobile phone screen; upon full engagement of the screen protector attaching device main body (1) with the mobile phone (6), the reinforced glass film (3) positions above a screen of a mobile phone (6), wherein within the relative upper and lower extremities of the reinforced glass film (3), the lower end contacts a screen edge of the mobile phone (6) while the upper end, due to the presence of the stopper (4), is obstructed by the stopper (4) from making contact with the upper screen edge of the mobile phone (6), thus maintaining a gap; the reinforced glass film (3) directly contacts the lower screen edge of the mobile phone (6) and, by leveraging the inherent self-adhesive property of the reinforced glass film (3), achieves a progressive bottom-up auto-adhesion, but owing to the stopper (4), the reinforced glass film (3) cannot fully adhere to the screen of the mobile phone (6), resulting in a residual gap (100) that prevents further auto-adhesion; finally, after removal of the screen protector attaching device main body (1) and detachment of the reinforced glass film (3) from the connector (2), the reinforced glass film (3), under the influence of gravity and self-adhesiveness, achieves complete adhesion between the film and the screen of the mobile phone (6), concluding the film application process. ### Claim 2 (depends on 1) The improved cell phone screen protector attaching device equipped with the reinforced glass film defined in claim 1, wherein the stopper (4) is convex blocks or convex bars configured on an outer side of one end of the reinforced glass film (3). ### Claim 3 (depends on 1) The improved cell phone screen protector attaching device equipped with the reinforced glass film defined in claim 1, wherein the stopper (4) is convex blocks or convex bars configured on both sides of the reinforced glass film (3). ### Claim 4 (depends on 1) The improved cell phone screen protector attaching device equipped with the reinforced glass film defined in claim 1, wherein the stopper (4) is convex bars configured on both sides of the reinforced glass film (3), the convex bar having an inclined surface that touches the screen of the cell phone. ### Claim 5 (depends on 1) The improved cell phone screen protector attaching device equipped with the reinforced glass film defined in claim 1, wherein the holding space (11) is enclosed by continuous or discontinuous edgings (111). ### Claim 6 (depends on 1) The improved cell phone screen protector attaching device equipped with the reinforced glass film defined in claim 1, wherein the release film (5) has an extended portion (51) extending beyond the area of the reinforced glass film (3). ### Claim 7 (depends on 6) The improved cell phone screen protector attaching device equipped with the reinforced glass film defined in claim 6, wherein first positioning mechanisms matching each other are formed between the bottom surface of the screen protector attaching device main body (1) and the extended portion (51). ### Claim 8 (depends on 1) The improved cell phone screen protector attaching device equipped with the reinforced glass film defined in claim 1, wherein the connector (2) is adhesive layer or adhesive component, the connector (2) is fixed on the bottom surface of the screen protector attaching device main body (1), the reinforced glass film (3) is adhered inside the area of the holding space (11) and is suspended through the connector (2). ### Claim 9 (depends on 1) The improved cell phone screen protector attaching device equipped with the reinforced glass film defined in claim 1, wherein the connector (2) is a tape, a sticky film, or an adhesive plate having one adhesive side and is bendable, the connector (2) is configured on the top surface of the screen protector attaching device main body (1), and the screen protector attaching device main body (1) is configured with a window (12) or notch that goes from the top down, and the connector (2) is connected to the upper surface of the reinforced glass film (3) through the window (12) or notch. ### Claim 10 (depends on 8) The improved cell phone screen protector attaching device equipped with the reinforced glass film defined in claim 8, wherein second positioning mechanisms matching each other are formed between the top surface of the screen protector attaching device main body (1) and the connector (2).
