In addition, the cables of the mini computer host with multiple expansion interfaces are prone to entangle with each other during work. Moreover, the data line plug and the interface are inevitably dragged during plugging, which causes the cable to fall off, resulting in interruption of data transmission and affecting the user experience of the computer.

[0016] The technical solution provided in this application has at least the following technical effects or advantages: 1. By employing an interface component, this invention effectively solves the problem of existing mini PC hosts, which, in pursuit of a compact size, simplify the number of interfaces in their design. For users who need to connect multiple monitors, storage devices, network devices, audio devices, etc., the interface configuration is clearly insufficient. Furthermore, in mini PC hosts with multiple expansion interfaces, the cables are prone to tangling during operation. Additionally, the insertion and insertion of data cable plugs and interfaces inevitably drags the cables, causing them to detach, interrupting data transmission, and affecting the user experience. This invention, through its interface component, can limit the insertion of cables into interfaces in mini PC hosts with multiple interfaces, preventing tangling and detachment. It also prevents data cable plugs and interfaces from detaching during dragging. The component provides a buffering effect when the data cable is dragged in various directions, producing different buffering effects depending on the dragging force. An alarm is triggered when the dragging force is large, and users can set alarm values ​​according to their actual needs, thereby preventing data cable plugs and interfaces from detaching during dragging, preventing data transmission interruptions, and improving the user experience.

[0017] 2. Due to the use of heat dissipation components, the problem of heat generation during operation being difficult to dissipate quickly due to the small space of the mini PC host is effectively solved. The fixed cooling fan of traditional PC hosts causes excessive heat concentration in certain areas of the host, which cannot be dissipated in time, thus affecting the overall heat dissipation effect. In addition, the heat dissipation effect of existing mini PC hosts is limited and cannot improve the heat dissipation effect when the mini PC host is working, which can easily cause the mini PC host to lag. This invention can improve the air circulation effect inside the host by changing the position of the fan through the heat dissipation components. It can increase the air flow channel while the fan moves, making it easier for external cool air to enter the host, come into contact with the heat-generating hardware, absorb heat and become hot air, and then be discharged from the host through other ventilation holes.
