Technical Field

[0001] This utility model relates to the technical field of mobile phone protective film processing fixtures, and in particular to a mobile phone protective film processing fixture. Background Technology

[0002] A screen protector is a thin film material used to protect the screen of a mobile phone. It is mainly made of materials such as PP, PVC, PET, and TPU. Its main function is to prevent scratches and wear on the screen, and to reduce the risk of screen breakage. During the manufacturing process of a screen protector, clamps are usually used to hold and support the film, preventing it from moving during cutting, drilling, and other processing.

[0003] Chinese patent CN222289973U discloses a mobile phone screen protector processing fixture, comprising a mounting base, a support rod, an electric drive belt, a tray, a mounting column, an electric slider, a support frame, and a movable plate. The support rod is symmetrically mounted on the upper part of the mounting base, and the electric drive belt is movably mounted on the support rod. A tray is mounted on one side of the support rod. The mounting column is symmetrically mounted on the left side of the mounting base, and the electric slider is symmetrically and movably mounted on the mounting column. A support frame is mounted on the electric slider, and a movable plate is symmetrically and movably mounted on one end of the support frame. This invention uses a drive motor to rotate the threaded rod, which opens the clamping plate and clamps the mobile phone screen protector, thus facilitating the processing of mobile phone screen protectors.

[0004] Existing mobile phone screen protector processing fixtures suffer from problems such as inconvenience in flexibly adjusting the clamping position according to the length and width of the screen protector, resulting in insufficient flexibility in use. To overcome these disadvantages, this utility model provides a mobile phone screen protector processing fixture. Utility Model Content
