As shown inFIG.8, each moving block4is provided with the installation cavity9, the rear end of each moving block4is provided with the limiting hole connected to the installation cavity9; each installation box5is provided with the rectangular sliding cavity10connected to the installation cavity9; each sliding cavity10is provided with the auxiliary board11that slides forward and backward, the front end of the auxiliary board11is made of rubber material, which will not create scratches the protective film8; the auxiliary board11can freely slide back and forth in the sliding cavity10, each auxiliary board11is fixedly installed with a pull rod12in the installation cavity9, the rear end of each pull rod12slides in the limiting hole, and each pull rod12is provided with springs13; one end of each spring13is fixedly connected to the auxiliary board11, the other end is fixedly connected to the rear wall of the installation cavity9, the spring13can be provided as existing suitable plastic or metal spring.

As shown inFIGS.1-8, rectangular holes14are respectively opened at the upper and lower ends on the left side and on the right side of the film applying box1respectively; the rectangular holes14are connected to the accommodation cavity2, and compression blocks15are installed inside each rectangular hole14, the compression block15has the characteristics of compression and automatic reset.

As shown inFIG.4, the inner walls of the upper and lower ends of the film application box1are fixedly provided with compression pieces16. When the compression pieces16are compressed, they have the characteristic of deformation.

As shown inFIG.3, auxiliary rings17are fixedly installed on the inner wall of each limiting ring7, a certain distance is reserved between the front end of each auxiliary ring17and the corresponding limiting ring7, and the depth of the distance is the same as the thickness of the protective film8.

As shown inFIGS.3and5, the left and right ends of the film application box1are respectively provided with placing opening18, the size of the placing opening18is the same as that of the positioning opening, and the size of the sealing strip is smaller than that of the placing opening18; one end of each compression block15is provided with a inclined surface19respectively.

As shown inFIG.7, an auxiliary circular hole is provided in the middle of the film application box1, and installation opening are provided on the left and right sides of the auxiliary circular hole on the film application box1, rubber suction cups20are fixedly installed in each installation opening, and suction cup cavities are respectively provided at the front end of each suction cup20; each suction cup cavity is slidably installed with a suction plate21, and each suction plate21is rotatably installed with a pulling shaft22, each pull shaft22is threaded installed on the rear end of the corresponding suction cup20.

The working principle of the present invention:

Specifically, during use, firstly clean the phone screen and the protective film8, then adjust the four moving blocks4to the appropriate positions, hold the protective film8and place it between the two limiting rings7, so that the rear end of the protective film8is completely in contact with the front end of the auxiliary ring17and the front end of the suction plate21; the two sealing strips are located in the positioning opening and placing opening18, then rotate the two pulling shafts22, the pulling shaft22gradually moves backward as it rotates, two suction plates21move backward along the suction cup cavity, forming a negative pressure between the two suction plates21and the protective film8, thereby sucking the film8; manually remove the sealing strip and remove the protective tape, hold the film application box1and approach the phone screen. After that, press the lower end of the phone against the lower compression piece16, the compression piece16will be compressed and deform towards the film application box1, then press the upper compression piece16by hand, which will compress and deform towards the film application box1until the upper and lower ends of the phone are located between the two compression pieces16. At this point, the two compression pieces16can be rebounded and clamp the phone, making it more stable.

Gradually bring the film application box1closer to the phone screen, at this time, the left and right ends of the phone are synchronously pressed and in contact with the inclined surface19; as the film application box1continuously approaches the phone, the corresponding compression blocks15are pressed on the left and right ends of the phone, and multiple compression blocks15are rebounded to clamp the phone until the phone screen contacts the front end of the protective film8; after the film application box1is completely installed with the phone, press the back end of the protective film8by hand through the auxiliary circular hole, in order to make the middle of the protective film8adhered on the phone screen, preventing bubbles from appearing during the applying process, then make each moving block4slide freely along the corresponding sliding groove hole3, each auxiliary board11can slide and press the protective film8while moving, making it tightly applied with the phone screen and preventing the appearance of bubbles.

After completing the film application on the phone, rotate the two pulling shafts22in reverse, at this time, the two suction plates21move forward until the two suction cups20no longer sucked with the film application8, then slowly remove the phone from the film application box1. When it is difficult to remove the phone from the film application box1, push each pulling rod12forward, the spring13is stretched, the auxiliary board11applies force to the phone screen, allowing the phone to separate from the film application box1quickly. In this way, each component gradually returns to original state and wait for the next use. This not only makes the phone film more tightly, but also less prone to make bubbles, making the film application more stable and efficient.

In the present invention, the use of orientation words such as “upper”, “lower”, “inside”, “outside” are only for the convenience of description, rather than indicating or implying the specific orientation, therefore it should not be construed as being limited to the description of the following embodiments.
