[0028] Please see Figure 1 , Figure 2 , Figure 3 One end of spring 10 is welded to movable ear 9, and the other end of spring 10 is welded to guide block 7. Through the setting of spring 10, movable ear 9 can be connected and used. Multiple friction grooves 11 are opened on the surface of insertion rod 8. Multiple friction grooves 11 are arranged in a ring array on insertion rod 8. Through the setting of friction grooves 11, the feel of insertion rod 8 can be improved.

Through the setting of reinforcing rib 16, the support strength of support column 15 can be guaranteed.

[0029] Please see Figure 1 , Figure 2 , Figure 4An adjustment mechanism 18 is provided on the support frame 12. The adjustment mechanism 18 includes a motor 180. The motor 180 is fixedly installed on the top inner side of the support frame 12. The output shaft of the motor 180 is fixedly connected to a screw 181. A screw cylinder 182 is threadedly connected to the outer side of the screw 181. The screw cylinder 182 is fixedly connected to the slide plate 14. A rotating column 183 is fixedly sleeved on the outer side of the screw 181. A locking hole 184 is opened on the surface of the rotating column 183. A telescopic block 185 is slidably connected to the inner wall of the support frame 12. The telescopic block 185 is close to the screw... A locking rod 186 is fixedly connected to the end face of the rod 181. The locking rod 186 is slidably connected to the locking hole 184. A connecting plate 187 is fixedly sleeved on the outside of the telescopic block 185. A spring 188 is provided on the outside of the telescopic block 185. Through the action of the motor 180, screw 181 and other structures, the sliding plate 14 can be driven to move the support column 15 to adjust the position of the tire body 17. Under the action of the locking hole 184, locking rod 186 and other structures, the screw 181 can be limited, thereby positioning the tire body 17 for use.

[0030] Please see Figure 1 , Figure 2 , Figure 4 Multiple locking holes 184 are provided, and the multiple locking holes 184 are arranged in a ring array on the rotating column 183.

[0031] The specific implementation process of this utility model is as follows: In use, the tire body 17 can be supported and placed by the setting of the support column 15. The output shaft is driven to rotate by the motor 180, which drives the screw 181 to rotate. Under the threaded connection, the screw cylinder 182 can be driven to move, so as to drive the slide plate 14 to slide along the inner wall of the slide groove 13, thereby driving the support column 15 to move and adjust the position of the tire body 17.

[0032] When the motor 180 drives the output shaft to rotate, it can drive the rotating column 183 to rotate. Under the pressure of the inner wall of the locking hole 184, it can push the locking rod 186 to move, thereby driving the telescopic block 185 to slide along the inner side of the support frame 12 and driving the connecting plate 187 to move, causing the second spring 188 to deform, and finally causing the locking rod 186 to disengage from the locking hole 184. Under the action of force, the locking rod 186 can slide along the surface of the rotating column 183. When the locking rod 186 is inserted into the next locking hole 184, the second spring 188 returns to its deformation to push the locking rod 186 into the locking hole 184, limiting the rotating column 183, and then using it to finely adjust and control the position of the tire body 17.

[0033] The filling core container 4 allows for the placement and use of the filling core. Under the action of the filling core, the tire puncture can be filled. The insert rod 8 can be pulled downwards to slide along the inner wall of the guide block 7, and the moving ear 9 can be moved, causing the spring 10 to deform. Finally, the insert rod 8 is disengaged from the positioning rod 6. Then, the adjustable pressure air pump 5 is pulled away from the support plate 3, making it easy to quickly remove the adjustable pressure air pump 5. Under the action of the adjustable pressure air pump 5, air can be injected into the valve of the tire body 17 in the opposite direction to adjust the supporting force of the filling core.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
