The power output shaft drives the tire installation device to install the tire, or drives the tire removal device to remove the tire. Since the motor needs to turn the power 90 degrees after horizontally outputting the power and then output it upward to the base, when fixing the power device to the base, it is necessary to ensure the concentricity of the power output shaft and the shaft hole and sleeve on the base. If the concentricity is not good, it is easy to wear and reduce the service life;

[0003] However, the power structure of the tire changer in the existing technology still has some shortcomings. For example, if there is an error in the installation position, the reducer and the power output shaft fixed by the support column cannot remain concentric with the shaft hole, and wear will also occur, which is easy to produce unqualified products. Therefore, the existing technology needs to be improved. Summary of the invention

[0029] In the specific implementation process, it is worth pointing out that the power device 2 is fixed to the bottom end of the base 1, the base 1 is composed of a top plate 101, a power output shaft hole 3 is opened on one side of the upper end of the top plate 101, and a power bearing seat 4 is fixed inside the power output shaft hole 3. The power source can be an electric motor, or a hydraulic motor or a pneumatic motor, the power provided by which is output by the main shaft and enters the intermediate reducer 202, one side of the shell of the intermediate reducer 202 is fixedly sealed and connected to the power source 201, and the other side is fixedly sealed and connected to the shell of the steering reducer 203. The intermediate reducer 202 reduces the main shaft power of the power source 201 and increases the torque, and then transmits it to the steering reducer 202, and passes through the steering reducer. The upward power output shaft 7 is output vertically, and the power output shaft 7 can rotate in the power bearing seat 4. The two side walls of the steering reducer 203 are vertically fixed with ear plates 8. The ear plate screw holes a9 opened on each ear plate 8 correspond to the positions of the ear plate screw holes b6 opened on the top plate 101, and have the same specifications.
