Description

Technical Field

[0001] The utility model relates to the technical field of terminal device film pasting, in particular to a film pasting device that reduces sliding friction. Background Art

[0002] The display screen of a terminal device requires a protective film to prevent it from being scratched or broken. A film-applying device is a structure that can apply a film to a terminal device. The film-applying device is equipped with a film applicator, which moves to apply the protective film to the display screen. Current film applicators on film-applying devices have high friction when moving, requiring significant effort from the user. This can lead to users being unable to accurately determine the amount of force required to move the applicator, causing the applicator to move at different speeds. This can result in the protective film being unevenly squeezed in certain locations, potentially causing bubbles to form. Utility Model Content
