[0003] With the development of natural language processing technology, its applications in various fields have been fully extended. For example, using natural language processing analysis to obtain evaluation data of students' skills has greatly improved the accuracy and timeliness retention of students' skill evaluations. Therefore, intelligent network terminals for students' skill evaluations are becoming increasingly popular. As shown in an intelligent terminal for college graduate skill evaluation based on natural language (publication number CN214202200U) disclosed on the Chinese Patent Network, when such a device is in daily use, based on a scanner that can be extended and retracted, when a document needs to be scanned, the scanner is extended through a driving mechanism to scan the document. Then, after the scanning information is obtained, the scanner is retracted into the housing again, and at the same time, the scanning information is transmitted to a control chip for data processing and analysis. Operations are performed through an operation keyboard and a touch display screen, and the information displayed on the touch display screen is observed to complete the network-based evaluation, recording, and storage of students' skills.

[0004] However, for the intelligent terminal for college graduate skill evaluation adopted in the above-mentioned public patent and the existing market, there are still some deficiencies: The existing method of using a scanner in a telescopic push-and-pull form to scan and identify students' evaluation information and using an obliquely placed touch screen for analysis and display has relatively single flexible use performance and poor flexible display performance for evaluation information. It cannot intuitively and conveniently provide a clear display effect to surrounding students, and has a large limitation in on-site use. Therefore, those skilled in the art have provided an intelligent network terminal for college skill evaluation to solve the problems raised in the above background technique.

An elevating lead screw 8 is rotatably connected inside the rod of the elevating vertical rod 2. A lifting slide 9 that is guided by the elevating vertical rod 2 is sleeved outside the shaft of the elevating lead screw 8. The bottom end of the shaft of the elevating lead screw 8 is installed with an elevating motor 7 inside the support of the foot support frame 1. A track chute 10 adapted to the lifting slide 9 is provided on the wall surface of the rod of the elevating vertical rod 2. By controlling the operation of the elevating motor 7, the elevating lead screw 8 is driven to rotate, and the lifting slide 9 is pushed to lift and slide along the direction of the arm of the elevating vertical rod 2, and then the rotating platform 3 is pushed to lift and displace, so as to adjust and align the height and azimuth of the scanner 5 and the touch screen acquisition terminal 6, so as to be more convenient for on-site students or teachers to operate and use.

[0029] A rotation and alignment mechanism is sleeved on the lifting platform of the elevating and alignment mechanism. The rotation and alignment mechanism includes a rotating platform 3 sleeved outside the lifting slide 9. A locking gear disk 12 is provided in the middle of the frame of the rotating platform 3. Two guiding sliders 13 are slidably connected inside the guiding groove of the rotating platform 3. An arm force support 4 is provided on one side of the support of the guiding slider 13. The rotating platform 3 is symmetrically provided with guiding chutes 11 that guide the guiding sliders 13.

By using the scanner 5, the student evaluation information content can be scanned, and the scanned information can be transmitted to the touch screen acquisition terminal 6 through the wireless antenna for analysis. At the same time, students or teachers can operate the touch screen acquisition terminal 6 to view, analyze, and display the evaluation information, providing a convenient and clear operation space and display vision for the on-site students.

[0032] The working principle of the present utility model is as follows: When using the intelligent network terminal to conduct a network evaluation of the student evaluation information, based on the casters of the foot support 1, the intelligent network terminal is pushed and displaced to the evaluation site. Then, by controlling the lifting motor 7 to work, the lifting lead screw 8 is driven to rotate, and the lifting slide 9 is pushed to slide up and down along the arm of the lifting vertical rod 2, and then the rotating table 3 is pushed to lift and displace to adjust and align the height and orientation of the scanner 5 and the touch screen acquisition terminal 6. Synchronously, the horizontal orientation of the scanner 5 and the touch screen acquisition terminal 6 can be adjusted by pushing the arm strength bracket 4 to swing horizontally, so as to provide convenient operation and clear display vision for students or teachers at a suitable height and horizontal display orientation.

[0033] Furthermore, during the evaluation work, based on the scanning and uploading of the scanner 5, the student evaluation information content is scanned, and the scanned information is transmitted to the touch screen acquisition terminal 6 through the wireless antenna for analysis. At the same time, students or teachers can operate the touch screen acquisition terminal 6 to view, analyze, and display the evaluation information, providing a convenient and clear operation space and display vision for the on-site students.

[0034] And after the subsequent evaluation is completed, the scanner 5 and the touch screen acquisition terminal 6 can be moved closer together to reduce the occupied space between the two, facilitating carrying, transportation, and placement.
