[0025] The sliding rod 504 is provided to prevent the moving block 505 from rotating along with the bidirectional screw rod 503 , thereby ensuring that the moving block 505 performs a stable linear motion.

[0026] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth noting that the sliders 508 are symmetrically fixedly connected to the left and right sides of the standing plate 507, and the opposite surfaces of the U-shaped plate 501 are provided with sliding grooves adapted to the sliders 508;

[0027] By providing a slider 508 that slides inside the slide groove, the stability of the lifting of the standing plate 507 can be improved.

[0028] According to the above working process, it can be seen that: through the provided lifting mechanism 5, the height of the slider 508 can be adjusted to meet the operating needs of examinees of different heights, ensuring that the electrical equipment on the opposing board 2 can be operated comfortably, thereby improving the applicability and practicality of the device.

[0029] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that the fixing mechanism 4 consists of a mounting cavity 401, a first motor 402, a connecting shaft 403, a bevel gear set 404, a transmission shaft 405, a gear 406, a moving column 407, a connecting plate 408, a guide rod 409 and a conical base 410.
