When the vertical tire changer with a double-sided tool 17 and an overturning structure in the embodiment is used, the wheel hub is clamped above the rotating chuck 8, and the rotating chuck 8 rotates to the horizontal position. A switch on the operating platform 3 is started for mounting or dismounting the tire. When the tire is mounted, the straight hook portion of the double-sided tool rotating structure 5 is located below the bent hook portion of the double-sided tool rotating structure 5. The operating platform 3 is configured for controlling the straight hook portion to walk to the position above a tire bead. Meanwhile, the small pressing wheel structure 6 is stretched to the position above the tire bead, and then the lifting seat is controlled to move downwards. In the process that the lifting seat moves downwards, the rotating chuck 8 drives the wheel hub to rotate by one circle to complete the mounting of a first crossing. The wheel hub continues to rotate downwards by one circle in the same method to complete the mounting of a second crossing. When the tire is dismounted, the small pressing wheel structure 6 is retracted, and the handball 15 is pulled upwards, so that the tool head 21 can freely rotate by 180°, and the bent hook portion is located below the straight hook portion. After the handball 15 is loosened, the locking pin shaft 16 falls into a round hole to achieve locking, and the bent hook portion hooks the tire. The rotating chuck 8 drives the wheel hub to rotate by one circle to complete the dismounting of the first crossing. Then, the large pressing wheel structure 7 walks to the edge of the wheel hub, the wheel hub rotates again, the tire is cut out of the edge of the wheel hub, and tire dismounting is completed.
