[0021] The support base device 2 includes a support base 12, a slide rail 13, a baffle 14 and a handle 15. The bottom end of the slide rail 13 is fixedly connected to the middle of the top end of the support base 12. The baffle 14 is symmetrically fixedly connected to the two ends of the support base 12. The handle 15 is fixedly connected to the top end of the baffle 14. The support base device 2 can be carried by lifting the handle 15.

[0022] The slide rail 13 is slidably connected to the inside of the slide groove 9. The tire is placed on the slide support frame 3. The slide groove 9 is driven to slide on the slide rail 13 by pushing the slide support frame 3 to drive the tire on the slide support frame 3 to move.

[0023] The side of the sliding support frame 3 close to the support column 10 is designed in an arc shape, and the support column 10 is arranged in an arc shape. The arc shape design is convenient for supporting and rotating the tire.

[0024] An anti-slip groove is provided at one end of the anti-slip ring 7 close to the plug 5. The fixing nut 6 is screwed close to the outer side of the sliding support frame 3 by external force until the anti-slip ring 7 is tightly attached to the outer side of the sliding support frame 3. The design of the anti-slip groove facilitates the anti-slip ring 7 to fix the sliding support frame 3.

[0025] The sliding support frame 3 is hollow in design, and the sliding support frame 3, the support base 12 and the slide rail 13 are all made of aluminum alloy, which reduces the weight and is easy to use.

[0026] The slide groove 9 is located between the two insertion holes 8 , and the sliding support frame 3 is balanced and fixed by two threaded rods 4 fixed on both sides of the slide groove 9 .

[0027] Grooves are respectively arranged on both sides of the top of the baffle 14 , and the threaded rod 4 is located above the grooves, so that the threaded rod 4 can pass through the top of the baffle 14 .

[0028] Working principle: during use, after the old tire is removed, first place the support base device 2 on the outside of the wheel position, and then use external force to stand the spare tire upright and place it between the two sliding support frames 3, and the outer side of the supporting roller 11 is close to the outer side of the spare tire. At this time, the spare tire is located on the outer side of the wheel. When the mounting hole of the spare wheel is lower than the wheel fixing bolt of the vehicle, the sliding support frame 3 is pushed to slide on the slide rail 13 by external force, and the sliding of the sliding support frame 3 drives the support column 10 to move, and the movement of the support column 10 drives the support roller 11 to move. Since the support roller 11 is close to the outer side of the spare tire, the support roller 11 rotates under the action of friction when the support roller 11 moves, and pushes the spare wheel to move upward until the spare wheel The mounting hole is at the same height as the fixing bolt, and then the fixing nut 6 is screwed close to the sliding support frame 3 by external force until the side of the anti-skid ring 7 away from the fixing nut 6 is close to the outer side of the sliding support frame 3. When the center of the spare tire is misaligned with the center of the wheel axle, the spare tire is pushed by external force, and the movement of the spare tire drives the sliding support frame 3 to slide until the center of the spare tire coincides with the center of the wheel axle, and then the spare tire is rotated. Under the action of friction, the rotation of the spare tire drives the supporting roller 11 to rotate, so that the spare tire is easily rotated until the mounting hole of the spare tire coincides with the fixing bolt on the vehicle, and then the spare tire is pushed to move toward the fixing bolt by external force until the mounting hole of the spare tire is completely installed on the fixing bolt, and the installation of the spare tire is completed.
