After the long strip 7 is separated from the slider 5, the elastic force of the tension spring 4 will pull the slider 5 to move in the direction close to the main body 1, so that the smoothing roller 8 is adapted to the sleeve inside the main body 1 to clamp the paper roll.

[0034] See also Figure 6 The clamping assembly includes a cover plate 10 located inside the groove 9, a positioning block 11 is arranged inside the groove 9, a positioning pin 12 fixedly connected to the cover plate 10 is slidably connected inside the positioning block 11, a fixing assembly is arranged between the positioning block 11 and the positioning pin 12, a limiting assembly is arranged at the outer end of the positioning pin 12, and a flip assembly is arranged at the outer end of the cover plate 10.

[0035] Example 2

[0036] The utility model provides a PCB dust removal anti-static dust sticky paper roll, wherein the same or corresponding parts as those in embodiment 1 are marked with the corresponding reference numerals of embodiment 1. For the sake of simplicity, only the differences from embodiment 1 are described below. Figure 5 The fixing component includes a magnet rod 15 located inside the positioning block 11 and a magnetic powder layer located on the surface of the positioning pin 12. The magnetic powder layer cooperates with the magnet rod 15 to fix the cover plate 10 inside the groove 9, so that the end of the paper roll can be stably clamped inside the groove 9. The flipping component includes a square groove 16 opened at the outer end of the cover plate 10. Two partitions 17 are fixedly connected inside the square groove 16. The setting of the partition 17 can facilitate the user to operate the cover plate 10.

[0037] See also Figure 6 The limiting assembly includes a limiting groove 13 formed at the outer end of the positioning pin 12, and a limiting block 14 fixedly connected to the positioning block 11 is slidably connected inside the limiting groove 13. The limiting groove 13 and the limiting block 14 cooperate with each other to prevent the cover plate 10 from detaching from the groove 9.

[0038] When in use, the user first rolls the main body 1 to adhere the paper roll to the surface of the object. While the paper roll is adhering, the smoothing roller 8 rolls and smoothes the paper roll to make the paper roll contact with the object more closely, thereby effectively improving the subsequent removal of pollutants and dust. After cleaning, the user pulls the long strip 7 to separate the slider 5. At this time, the elastic force of the tension spring 4 drives the slider 5 to move in the direction close to the main body 1 inside the slide groove 3, so that the smoothing roller 8 is adapted to the sleeve inside the main body 1 to clamp the paper roll and prevent the paper roll from loosening. Finally, the user places the end of the paper roll in the groove 9, and the end of the paper roll is clamped and fixed by cooperating with the cover plate 10, which makes it convenient for the user to find the end of the paper roll when using it again.

[0039] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
