[0031] The ends of the two moving platforms 2 that are away from each other are both equipped with a rotating mechanism, so that the rotating shaft 3 is limited and driven to rotate by the rotating mechanism.

The second sliding block 16 is slidably connected to the positioning disk 11, so that when the second sliding block 16 is located inside the positioning disk 11, the rotating disk 12 cannot rotate, and the rotating shaft 3 and the positioning frame 4 cannot rotate. A tension spring 13 is fixed to the end of the two movable platforms 2 that is away from each other and located between the rotating shaft 3 and the positioning disk 11. The tension spring 13 is fixed to the rotating disk 12, so that when the second sliding block 16 is separated from the slidably connected positioning disk 11, the rotating disk 12 moves away from one end of the positioning disk 11 and drives the tension spring 13 to stretch.

[0033] The use process of a maintenance frame provided by the utility model is as follows: when the motor vehicle tire that needs to be repaired is placed on the top of the support platform 1 in the state of installation and use, the mobile platform 2 drives the positioning frame 4 to clamp the tire through the rotating column 5 through the movement between the two moving platforms 2, and the tire can be rotated by the rotation of the rotating column 5 and the positioning frame 4, so as to facilitate the maintenance personnel to view the tire surface. When the tire needs to be turned over, the rotating disk 14 is pulled to drive the rotating disk 12 to move, and the rotating disk 12 and the first sliding block 15 are moved at the same time. At this time, the first sliding block 15 is allowed to slide inside the rotating shaft 3 and the rotating disk 12 is allowed to move away from one end of the positioning disk 11, and the movement of the rotating disk 12 drives the tension spring 13 to stretch, so that the second sliding block 16 is separated from the slidingly connected positioning disk 11, and then the rotating disk 14 is rotated, so that the rotating disk 14 drives the first sliding block 15 to rotate, and the rotation of the first sliding block 15 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the positioning frame 4 to rotate synchronously, so that the rotation of the positioning frame 4 drives the tire to turn over.
