The existing technology is similar to the positioning base of an adjustable film applicator. The structure with publication number CN222555250U includes a fixed base and an adjustment base. The adjustment base is slidably mounted on one end of the fixed base. The phone to be filmed is placed between the fixed base and the adjustment base. The adjustment base is equipped with a tail plug positioning piece for fixing the phone's tail plug, and the adjustment base is also equipped with a film module positioning column for installing the film module. This invention has a simple overall structure, easy operation, low production cost, and can easily position mobile phones of different sizes, achieving universality. However, there are still areas for improvement in this device.

[0004] The existing device mainly uses an elastic component to adjust the tail plug positioning piece, which causes some mobile phones to slide during the film rolling process, resulting in problems such as film offset. At the same time, some devices find it difficult to adjust the spacing of the corner positioning blocks according to the width of the mobile phone, which makes it difficult to stably place mobile phones of different width specifications, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a film applicator with an adjustable positioning base is proposed. Summary of the Invention
