[0002] A notebook contains a large number of injection molded parts, including a rotating shaft sleeve, a power button, keys, a cover plate, etc. In order to increase the aesthetic appearance and wear resistance of the notebook, it is necessary to perform surface spraying on the surfaces of these injection molded parts to form surface layers of various colors. These surface layers have characteristics such as metallic luster and matte surfaces, and at the same time have high wear resistance.

[0003] Currently, during the spraying process of injection molded parts of a notebook rotating shaft sleeve, it is necessary to use a carrier to support the injection molded parts for better spraying. When the existing injection molded parts are connected and fixed to the carrier, not only are the operation steps more troublesome, the loading and unloading take a long time, but also the injection molded parts are easily damaged. Moreover, after the existing jig fixes the injection molded parts, there is more shielding on the surface of the injection molded parts, which is not conducive to the coverage of the coating during spraying.

[0004] Based on this, the utility model designs a spraying carrier for injection molded parts of a notebook rotating shaft sleeve to solve the above problems. Content of the Utility Model
