[0035] The working principle of the present utility model:

[0036] When installing and fixing the display screen 3, place the display screen 3 on the surface of the box body 41. The gravity of the display screen 3 presses the placing plate 422 downward, causing the placing plate 422 to slide downward on the surface of the moving rod 421, and at the same time stretching the tension spring 423. While the placing plate 422 moves, it drives the first rack 424 to move downward. The downward movement of the first rack 424 drives the first gear 442 to rotate. The rotation of the first gear 442 drives the second gear 443 to rotate through the transmission shaft 441. The rotation of the second gear 443 drives the two second racks 433 engaged with it to move together. While the two second racks 433 move together, they drive the two clamping plates 432 to move together on the surface of the sliding rod 431, thereby fixing the display screen 3. When removing the display screen 3, pull the display screen 3 upward. When pulling out, the tension spring 423 will pull the placing plate 422 upward, and at the same time drive the first rack 424 to move upward to drive the first gear 442 to rotate. The rotation of the first gear 442 drives the second gear 443 to rotate through the transmission shaft 441. The rotation of the second gear 443 drives the two second racks 433 to move to the left and right sides to drive the two clamping plates 432 to open, thereby removing the display screen 3.

[0037] In summary, for the auxiliary fixing component for the vehicle-mounted display screen, by using the cooperation of the vehicle body 1, the connecting rod 2, the display screen 3, the fixing device 4, the box body 41, the pressing component 42, the moving rod 421, the placing plate 422, the tension spring 423, the first rack 424, the clamping component 43, the sliding rod 431, the clamping plate 432, the second rack 433, the linkage component 44, the transmission shaft 441, the first gear 442, the second gear 443, the anti-slip pad 5 and the moving groove 6, it solves the problems that the existing vehicle-mounted display screens for driving tests are usually fixed on the connecting rod with screws for installation and fixation, which is rather troublesome during installation and disassembly, and the screws are prone to thread slipping during a certain period of use, resulting in difficult disassembly and assembly and inconvenient taking and replacement.
