[0026] Embodiment 2:

[0027] See also Figure 1-4, this embodiment provides a technical solution on the basis of the first embodiment: the lifting component 100 includes a double-axis motor 101 fixedly installed on the upper end surface of the bottom plate 1, and the output ends of both ends of the double-axis motor 101 are fixedly installed with connecting rods 102, and the two connecting rods 102 are rotatably connected to the connecting seats 103 at one end away from the double-axis motor 101, and the bottom ends of the two connecting seats 103 are fixedly installed on the upper end surface of the bottom plate 1, and the two connecting rods 102 are fixedly installed with a transmission rod 104 at one end away from the double-axis motor 101, and the two transmission rods 104 are rotatably connected to the transmission rod 2 105 at one end, and the two transmission rods 2 105 are rotatably connected to the lower end surface of the bearing plate 3 at one end, and the four corners of the lower end surface of the bottom plate 1 are fixedly installed with guide rods 106, and the top ends of several guide rods 106 are all movable and penetrate to the top of the bearing plate 3 and fixedly installed with limited blocks 107. The height of the positioning tire can be effectively adjusted by setting the lifting component 100. When the height of the positioning tire needs to be adjusted, the double-axis motor is started. The machine 101 drives the transmission rod 104 at one end of the connecting rod 102 to rotate. The transmission rod 104 drives the tire on the top of the supporting plate 3 to be raised and lowered through the mutually matching groove with the transmission rod 2 105, so as to adjust the height of the positioning tire. The driving gear 204 is meshed with the driven gear 205. The tops of several connecting columns 209 all penetrate to the tops of the corresponding limiting grooves 206. The L-shaped sliding rod 208 drives the connecting column 209 to slide and connect in the convex groove 207. The limiting groove 206 is arranged in an arc shape. The outer surfaces of several L-shaped sliding rods 208 match the inner walls of the corresponding convex grooves 207. Pressure sensors 6 are arranged on the sides of several arc-shaped clamping plates 210. The pressure sensors 6 can sense the squeezing force of the arc-shaped clamping plates 210 on the tire to prevent the tire from being squeezed and deformed due to excessive pressure. A controller 7 is arranged on one side of the top of the supporting plate 3. The driving motor 203, the dual-axis motor 101 and the pressure sensor 6 are all electrically connected to the controller 7.

[0028] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0029] During operation, the tire is first placed outside several arc-shaped clamping plates 210, and then the driving motor 203 drives the driving gear 204 to rotate. Due to the meshing connection between the driving gear 204 and the driven gear 205, the driven gear 205 is driven to rotate. While the driven gear 205 is rotating, the L-shaped sliding rod 208 drives the connecting column 209 to move in the limiting groove 206, thereby driving the L-shaped sliding rod 208 to move in the convex groove 207. The L-shaped sliding rod 208 and the arc-shaped clamping plate 210 clamp and position the inner wall of the tire. After the tire is positioned, the height of the rear tire is adjusted according to demand. By starting the dual-axis motor 101 to drive the transmission rod 104 at one end of the connecting rod 102 to rotate, the transmission rod 104 drives the tire on the top of the supporting plate 3 to be raised and lowered through the mutually matching groove between the transmission rod 2 105. The operation is simple and practical.
