Description

Technical Field

[0001] The utility model relates to the technical field of substrate surface covering materials, and in particular to a surface covering mechanism. Background Art

[0002] Coating materials on the surface of a substrate can change the flexibility or smoothness of the substrate surface. For example, coating the surface of a mobile phone screen can protect the mobile phone screen. There is currently a watch support that is used to support a watch for display or to provide support during transportation and packaging. This watch support is mostly a plastic substrate with flocked fabric coated on the outer periphery, and the fabric is adhered to the substrate.
