Obviously, the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0032] Referring to the drawingsFigure 1 To the attached Figure 6 The utility model discloses an L type fluoroplastic ring's polishing device, include: fluoroplastic ring fixed disc 2 and fluoroplastic ring compression ring 3,

[0033] The edge of fluoroplastic ring fixed disc 2 is formed with annular positioning groove 21 for embedding L type fluoroplastic ring 1, and the surface edge of fluoroplastic ring fixed disc 2 is evenly provided with first connecting hole 22,

[0034] Fluoroplastic ring compression ring 3 covers the top surface of fluoroplastic ring fixed disc 2, and second connecting hole 31 corresponding to first connecting hole 22 is evenly provided on fluoroplastic ring compression ring 3, fluoroplastic ring compression ring 3 and fluoroplastic ring fixed disc 2 are fastened by bolt fastener 4 passing through first connecting hole 22 and second connecting hole 31, so that L type fluoroplastic ring 1 is compressed between fluoroplastic ring compression ring 3 and fluoroplastic ring fixed disc 2, and the sidewall surface of L type fluoroplastic ring 1 is exposed.

[0035] In order to further optimize the above technical scheme, a plurality of lightening holes 23 are evenly distributed on the fluoroplastic ring fixed disc 2. By providing a plurality of lightening holes on the fluoroplastic ring fixed disc, the weight of the entire polishing device can be effectively reduced, facilitating operation and transportation, especially when frequent movement or installation on different equipment is required, reducing weight can improve work efficiency. Reducing the amount of material used reduces production costs and is also beneficial to environmental protection. The lightening holes are reasonably designed, as shown in FIG. Figure 2 The design of the lightening holes will not have a negative impact on the structural strength of the fluoroplastic ring fixed disc, ensuring the reliability and stability of the device during use.

[0036] In order to further optimize the above technical scheme, a center support 24 is downwardly extended in the middle of the bottom surface of the fluoroplastic ring fixed disc 2, and the center support 24 is a hollow structure.
