[0075] In a specific embodiment, the working process of the above-mentioned teaching, testing, and practice integrated terminal device is as follows: When in use, the device is fixed or placed in a suitable position, and a suitable power cord is connected to the AC power port 18 for power supply. An external network cable is inserted into the network port 19 to establish network communication. The device is controlled via the AI ​​all-in-one machine 3 or an external expansion device. According to the electromechanical control logic, the first motor 214 is first started to rotate the first arm assembly 22.

The second camera 223 reaches the designated position, and the signal from the first signal module 215 is transmitted to the second arm base assembly 51. Upon receiving a signal, the push rod 513 begins to move until it contacts the micro switch 514 at the upper end of the second arm base assembly 51. The upper micro switch 514 outputs a signal to the second motor 534, activating the second motor 534 and causing the cantilever assembly 52 to rotate until it contacts the second signal module 523. At this point, the cantilever assembly 52 stops rotating and locks itself. The third camera 524 then reaches the designated position, creating a comprehensive, blind-spot-free recording and teaching scene from directly above, in front, and to the right. The teacher's demonstration or the student's operation records and training content are stored on the AI ​​all-in-one machine 3 via network transmission, facilitating teacher instruction and student practical assessment. After the teacher's instruction and student practical assessment are completed, the device can be automatically rotated and retracted with a single click via the teacher's operating AI all-in-one machine, tablet, or a dedicated teacher app, achieving automatic storage.

[0076] In the above implementation process, the control principles of the first signal module 215, the second signal module 523, and the micro switch 514 are existing technologies and will not be elaborated here.
