Pen holder with simulated dermatoglyph art paint surface and processing method of pen holder

The invention provides a pen holder with a leather-texture-simulated art paint surface and a processing method of the pen holder. The pen holder comprises a pen holder shell, a crack primer layer is sprayed on the outer wall of the pen holder shell, a crack paint layer is sprayed on the outer wall of the crack primer layer, a crack intermediate paint layer is sprayed on the outer wall of the crack paint layer, and a leather-texture-simulated finish paint layer is sprayed on the outer wall of the crack intermediate paint layer. The processing method comprises the following steps: S1, cleaning the surface of the penholder shell; s2, preparing paint liquid; and S3, the cleaned pen holder shell is subjected to paint spraying construction through machining equipment. The crack primer layer, the crack paint layer, the crack intermediate paint layer and the dermatoglyph finish paint layer are sequentially sprayed outside the pen holder shell, so that the outer wall of the pen holder shell forms a simulated dermatogl
