[0002] The computer case in the prior art is placed with its bottom surface on the upper surface of the support (10) to support its own weight. This installation method results in that no matter whether the computer case is placed on a desktop or on the ground, it needs to occupy a certain space. At the same time, when the plane where the case is located needs to be cleaned, the case needs to be moved back and forth to clean the area where it is located.

[0003] In order to solve the problem of computer cases occupying valuable space on the desktop and the ground, CN 218240829 U discloses a hanging computer case, which achieves the effect of hanging the case under a load (10) such as a desktop. However, in order to achieve relatively easy loading and unloading and maintenance of the case, the invention designs a set of relatively large lifting structures, and the actual function of the structure is to place the computer case that can be adapted on the market in the case placement box, and then install the case placement box on the adaptive hanging plate through the slide rail plate. The invention still has the following problems: 1. This installation method requires the case to remain as a whole. If it needs to be repaired later, the case needs to be taken out of the case placement box, which is very inconvenient; 2. The device is designed for a vertical case and cannot be well adapted to a horizontal case; 3. The size is relatively large, and when the space under the case needs to be cleaned, it may hinder the entry of cleaning tools such as a vacuum cleaner. Summary of the invention

21. The lifting device according to claims 13-18, characterized in that: It also includes a control module for controlling the operation of the driving device, wherein the control module is used to output a control signal to control the operation of the driving mechanism (8).

22. The lifting device according to claim 21, characterized in that: It also includes an input module, a measurement module and a control module, wherein The input module is electrically connected to the control module, and the input module is used to receive operation instructions; A measuring module, electrically connected to the control module, the measuring module being used to detect the relative distance between the computer case and the lower surface of the carrier (10); A control module, wherein the control module continuously receives data from the measurement module when the lifting device raises or lowers the computer case, and when the computer case reaches the highest height that can be raised or the lowest height that can be lowered, the control module stops the driving mechanism (8) from working to stop the lifting device from continuing to raise or lower the computer case.
