[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] like Figures 1-5 As shown in the figure, this utility model provides a scratch-resistant and wear-resistant polyester film, including a material roller 1 and a polyester film body 2 connected to the outer wall of the material roller 1. The outer wall of the material roller 1 is movably connected with a plurality of limiting seats 3 for limiting the polyester film body 2. The limiting seats 3 are located at both ends of the upper end of the polyester film. The polyester film body 2 includes a polyester film main body 21 and a first outer surface layer 22 and a second outer surface layer 23 bonded to the outer walls of both sides of the polyester film. This utility model, through the setting of the limiting seats 3, facilitates the limiting of the polyester film body 2 connected to the material roller 1, making it convenient for the polyester film body 2 to be put into and taken out. Moreover, the first outer surface layer 22 and the second outer surface layer 23 connected to the outer wall of the polyester film main body 21 prevent dust and debris from adhering to the outside of the polyester film, avoiding scratches, which would affect the quality of the polyester film and thus the quality of the film.

[0024] like Figure 1 As shown, the outer wall of the material roller 1 is provided with an external thread 11; the external thread 11 facilitates the threaded connection between the material roller 1 and the limiting seat 3, thereby limiting the polyester film body 2.

[0025] like Figure 3 As shown, the limiting seat 3 includes a limiting plate 31, with a threaded hole 311 penetrating the end face of the limiting plate 31. A screw cap 32 is fixedly connected to one side of the outer wall of the limiting plate 31, with the hole of the screw cap 32 corresponding to the threaded hole 311. The limiting plate 31 is threadedly connected to the outer wall of the material roller 1 through the threaded hole 311 and the external thread 11. The threaded hole 311 on the limiting plate 31 and the screw cap 32 connected to the limiting plate 31 facilitate the threaded connection between the limiting seat 3 and the material roller 1 through the external thread 11, making it convenient for the limiting seat 3 to be disassembled and installed, and also convenient for limiting the polyester film body 2.

[0026] like Figure 3 As shown, the outer wall of the screw cap 32 is provided with several arc-shaped grooves 322; the arc-shaped grooves 322 provided on the outer wall of the screw cap 32 facilitate the rotation of the screw cap 32, thereby driving the limiting plate 31 and realizing the movement of the mounting seat on the material roller 1.

[0027] like Figure 4As shown, the outer walls of the polyester film body 21, the first outer surface layer 22, and the second outer surface layer 23 are all provided with cutting grooves 24; the cutting grooves 24 facilitate the cutting and use of the polyester film.

[0028] like Figure 5 As shown, both the first outer outer layer 22 and the second outer outer layer 23 have tear openings 221 on one outer corner. The tear openings 221 provided in the first outer outer layer 22 and the second outer outer layer 23 facilitate the separation of the first outer outer layer 22 and the second outer outer layer 23 from the polyester film body 21 when it is needed, so as to facilitate the use of the polyester film body 21.

[0029] like Figure 2 As shown, the outer wall of the first outer layer 22 is provided with a plurality of protrusions 222, and the outer wall of the second outer layer 23 is provided with a groove 231 for receiving the protrusions 222. During the winding process, the polyester film body 2 is sleeved on the outer wall of the material roller 1, and the protrusions 222 provided on the first outer layer 22 extend into the groove 231 provided on the second outer layer 23, so that the polyester film body 2 is wound more tightly and stably on the material roller 1 to prevent loosening.

[0030] Working principle and usage process of this utility model:

[0031] In use, the polyester film body 2 is first wound around the outer wall of the material roller 1, and the protrusions 222 on the first outer surface layer 22 extend into the grooves 231 on the second outer surface layer 23, so that the polyester film body 2 is wound more tightly and stably on the material roller 1 to prevent loosening. Then, the screw cap 32 is rotated to drive the limiting plate 31 to move on the material roller 1, so that the limiting plate 31 contacts the polyester film body 2, which facilitates the limiting of the polyester film body 2 connected to the material roller 1, making it easy to put and take off the polyester film body 2. The first outer surface layer 22 and the second outer surface layer 23 connected by the outer wall of the polyester film body 21 prevent dust and debris from adhering to the outside of the polyester film, and avoid scratches, which would affect the quality of the polyester film and thus the quality of the film.
