The first end of the second side of the frame 10 is provided with a first limit groove 13, and the first positioning column 21 is located at the bottom wall of the first limit groove 13. The first limiting groove 13 is used for limiting the first end of the positioning film 41 to prevent the positioning film 41 from moving along the width direction of the frame 10. The second end of the second side of the frame 10 is provided with a second limiting groove 14, and the second positioning column 31 is located at the bottom wall of the second limiting groove 14. The second limiting groove 14 is used for limiting the second end of the positioning film 41 to prevent the positioning film 41 from moving along the width direction of the frame 10.

The film sticking device of the utility model adopts the following principle: when in use, the membrane assembly 40 is placed in the positioning cavity 11, so that two ends of the membrane assembly 40 extend out to the second side of the frame 10 through the two opening parts 18, the second end of the positioning membrane 41 is positioned through the second positioning column 31, and the first end of the positioning membrane 41 is positioned through the first positioning column 21; pulling the pull bar 44 by hand, the pull bar 44 drives the dust removing film 43 to be separated from the protective film 42 and approaches to the strip-shaped hole 12 along the gap between the protective film 42 and the electronic equipment 50, and finally the dust removing film 43 and the pull bar 44 are pulled out of the positioning cavity 11 through the strip-shaped hole 12; after the pull-out strip 44 is pulled out, a finger passes through the working hole 631 to press the membrane assembly 40, so that the middle part of the membrane assembly 40 can be bent and attached to the screen of the electronic equipment 50, and under the elastic action of the protective film 42, the attached area of the membrane assembly 40 and the screen of the electronic equipment 50 is gradually enlarged from the middle to the two sides, and finally, the film attaching is realized.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
