[0002] A computer case is a container for placing and fixing computer accessories. It is usually composed of a shell, brackets, panels and indicator lights. Its main function is to provide protection for the internal components of the computer, while helping to dissipate heat and provide shielding for electronic noise. As a part of computer accessories, the case mainly plays the role of placing and fixing various computer accessories, playing a supporting and protective role. In addition, the computer case plays an important role in shielding electromagnetic radiation. Because the case cannot quickly improve the performance of the entire machine like accessories such as the CPU, graphics card, and motherboard, it has not been listed as a key consideration in DIY.

A limit ring 18 is fixedly connected to the inner wall of the plug sleeve 16. A drive shaft 4 rotatably connected to the inner wall of the cavity 3 is installed on the inner wall of the limit ring 18. One end of the drive shaft 4 is fixedly connected to the drive wheel groove 5. Four positioning holes 19 plugged into the positioning column 15 are provided at one end of the plug sleeve 16.
