[0002] The laptop hinge is an important part that connects the body and screen of the laptop. It is both a connecting part and a part of the laptop shell. The laptop hinge shell not only needs to have the function of a hinge, but also needs to be aesthetically pleasing. Sandblasting is a processing method that can obtain a clean surface and surface treatment for secondary finishing operations. During the sandblasting process, high-speed steel abrasives are used to flatten rough surfaces, roughen smooth surfaces, shape surfaces, or remove surface contaminants. When sandblasting the existing laptop hinge shell, the products need to be fixed on the hanger one by one, and only 8-10 can be loaded at a time, which is inefficient and easy to damage the product. To this end, we propose a universal sandblasting tool for laptop hinge shells. Utility Model Content
