[0002] Computer Engineering is a highly comprehensive discipline that combines the basic theories and practical applications of computer science and technology. It aims to cultivate students' ability to manage technology and research, design, develop and maintain hardware and software systems in computer and related fields. The Computer Engineering Experiment Demonstration Device is a specially designed experimental tool that aims to help students deeply understand the theoretical knowledge of computer science and related engineering fields through practical operation and observation.

[0003] The experimental demonstration video can be displayed through a display device. However, when playing the video using a display, the teacher needs to pause the video when playing to the key point of the video to show the key point of the video. However, frequent video pauses are not conducive to the audience quickly knowing the general content of the video. At the same time, dust will stick to the surface of the display when used for a long time, which will affect the display of the display. Therefore, it is necessary to propose a computer engineering experiment demonstration device. Summary of the Invention

[0013] The second step is to start the drive motor to drive the rotating rod and the drive gear to rotate. The drive gear drives the two racks to move toward both ends. When the racks move, they simultaneously drive the second display to move outward, moving the second display outward from the inside of the first display. This adds two secondary screens to the demonstration device.
