AI Technical Summary
Existing sandpaper, especially at lower grits, is uncomfortable for operators to hold and can easily cause hand abrasions. It is also more likely to break when held improperly.
Design a wear-resistant sandpaper by bonding a reinforcing paper layer to the sandpaper layer, and setting three-finger openings, thumb openings and little finger openings on the reinforcing paper layer. Combined with the reinforcing sheet, a cavity structure is formed to adapt to different grip habits and prevent the openings from tearing and breaking.
It offers multiple grip options, reducing hand discomfort and the risk of wear, ensuring the sandpaper is not easily damaged during use, and improving its durability.

[0002] Sandpaper is a common abrasive tool, usually made of paper or cloth substrate, coated with abrasive particles such as silicon carbide, alumina, etc. According to the fineness of abrasive particles, sandpaper is divided into different mesh, the higher the mesh, the finer the particle, the smoother the polishing effect. Sandpaper is widely used in wood, metal, plastic and other materials polishing, polishing and deburring process. In use, the appropriate sandpaper mesh should be selected according to the material and polishing requirements of the workpiece to achieve the best effect. In addition, sandpaper also has different shapes and sizes, such as sheet, roll, strip, etc. to meet the needs of different occasions. In the polishing process, the abrasive particles of sandpaper will gradually wear out, so it needs to be replaced regularly to maintain the polishing effect.
[0003] In the actual practical process, the operator usually cuts the sandpaper quantitatively, holds the sandpaper by hand gesture, and drives the sandpaper to polish the surface of the processed object. For sandpaper with high mesh, the palm of the operator will not feel uncomfortable when holding it. However, for sandpaper with low mesh, the operator will feel obvious particle feeling during holding, and the pain will increase when holding hard. If the holding is improper, the sandpaper will also wear the palm of the operator.
