[0002] Computer is a modern electronic product. The host refers to the main body of the computer except the input and output devices. The computer host is mainly composed of the outer shell, motherboard, cooling fan, memory bar, power supply and other main components. During the assembly process of the computer host, the components need to be installed in the appropriate position in the outer shell.

[0003] After searching and according to the actual assembly work experience, in the current computer host installation process, there is still a lack of a relevant positioning device. In the process of installing memory bars and other components, in order to maintain the stability of the chassis, it is usually necessary to hold it by hand, but holding it by hand will affect the assembly efficiency of the host and prolong the assembly time of the host. There are also some simple clamping positioning devices on the market, but the positioning effect is limited. When the components are plugged in and installed, the chassis is easily stressed and overturned. Therefore, it is urgent to improve the above defects and provide a chassis positioning device for computer host assembly. Utility Model Content
