The abrasive layer 13 is fixedly installed on the adhesive layer 12. The abrasive layer 13 is the core part of the sandpaper and is directly involved in the grinding process. It determines the grinding ability and effect of the sandpaper. A wear-resistant coating 14 is fixedly installed on the abrasive layer 13. The wear-resistant coating 14 is used to improve the wear resistance of the sandpaper, so that it can maintain stable grinding performance in harsh working environments and extend its service life.

[0021] In detail, the shearing mechanism includes a slider 4, which is provided with a through hole 22. The slider 4 is slidably arranged on the sandpaper body 1 through the through hole 22. The slider 4 is in the shape of a square block. The through hole 22 is provided to facilitate the slider 4 to slide on the sandpaper body 1. The inner wall of the through hole 22 is provided with a cavity 24. The cross-sectional shape of the cavity 24 is convex. A limit plate 26 is slidably arranged on the inner wall of the cavity 24. The limit plate 26 is in the shape of a square plate. The limit plate 26 is provided to facilitate the installation of the push rod 21. The top of the limit plate 26 is fixedly installed with the push rod 21. The push rod 21 is provided to facilitate the movement of the cutter 23.

When the limit plate 26 slides, it will drive the cutter 23 to move downward until the cutter 23 cuts the sandpaper body 1, and then release the push rod 21. The limit plate 26 will drive the cutter 23 back to its position under the action of the spring 25. Through the above arrangement, the purpose of facilitating the cutting of polishing sandpaper is achieved, which is beneficial to the use of polishing sandpaper.
