At this time, the main body of the device can provide sufficient and stable bearing capacity for the horizontal sticking of the protective soft film 300, thereby effectively ensuring that the film sticking operation of the digital device screen can be carried out stably. Embodiment 3

[0034] Combination Figure 3 and Figure 4 As shown, on the basis of Example 1, the pressure-resistant roller 240 is composed of a core rod, a silicone sleeve roller and two gaskets, and the end of the inner end of the outer frame 230 is movably installed on the outside of the core rod, a slot is opened in the shell at the outer end of the main base 250, and a locking bolt is movably installed in the shell at the outer end of the main base 250, and the cleaning roller 280 is composed of an extended beam and a cotton roller.

[0035] The silicone sleeve roller is pre-installed on the outside of the core rod, and then the two ends of the inner end of the outer frame 230 are movably installed on the outside of the core rod, and the two ends of the inner end of the outer frame 230 are positioned and clamped with two washers.

At this time, the two beam rails 290 are movably mounted on the outside of the two main bases 250, and the two beam rails 290 will be fixedly mounted on the two ends of the cross bar 210. At this time, the two gaskets 220 will be fixedly mounted on the two ends of the cross bar 210 by the sub-bolts, and the rod body in the outer frame 230 is movably mounted in the horizontal grooves at the two ends of the cross bar 210;

[0037] When in use, the operator needs to place the digital device on the top of the tray 110, then insert one end of the protective soft film 300 along the gap between the anti-pressure roller 240 and the cleaning roller 280, and extend the protective soft film 300 into the bottom end of the anti-pressure roller 240 to fit on one side of the digital device screen, then release the positioning member 140, and the suction cup at the bottom of the positioning member 140 presses down on one end of the protective soft film 300, so that the protective soft film 300 can be stably attached to the screen, and then push the outer frame 230, at this time, the anti-pressure roller 240 can cooperate with the cleaning roller 280 to push the protective soft film 300 horizontally until the protective soft film 300 is accurately attached to the screen, and during the horizontal movement of the cleaning roller 280, the cleaning roller 280 coated with alcohol can clean the screen, thereby ensuring that the protective soft film 300 can be safely attached to the screen.
