[0010] Preferably, the two screws are arranged horizontally and are rotatably connected to the inner wall of the movable groove, so that the two screws can operate stably.

[0011] Preferably, through holes are formed on the bottom wall of the sink and between the mounting groove and the inner chamber; the heat released by the servo motor, the main bevel gear and the slave bevel gear can be gradually dissipated into the external environment through the through holes.

[0012] The utility model has the following beneficial effects:

[0013] The protective film installation positioner drives the hydraulic cylinder to extend the transmission rod, so that the sinker is pressed close to the protective film, so that the two positioning plates are in contact with the protective film, and then drives the servo motor to drive the main bevel gear and two slave bevel gears to operate, so that the two screws operate. At this time, the two positioning plates move away from each other and gradually spread the protective film on both sides of the equipment to be coated. The pressure generated by the two positioning plates on the protective film can ensure that the protective film is smoothly attached to the surface of the equipment to be coated (such as the A side of a laptop computer), and the film pasting of various parts of the surface of the equipment to be coated is completed, so that the film pasting area is larger and the effect is better.
