Furthermore, current tire removal tools and equipment are large, bulky, and space-consuming, making them difficult to operate, inconvenient, and easy to use. The replacement process requires multiple people working together, is complex, and poses safety hazards. Therefore, there is a need for an innovative, portable, labor-saving auxiliary device for tire removal on automotive wheel-side axles. This device should be rationally designed, reducing size and weight, and be easy to use, store, carry, repair, and relocate. It should be highly operable. It can be used in combination with other tools; when not in use, it can be separated and used as a pry bar for traditional tire reassembly. It can also replace different types of tire removal tools or equipment. It is easy to store, operate, repair, and relocate.

[0003] The main problems with existing technologies are: Traditional manual tire removal and replacement methods, involving pulling and forcibly pulling, result in uneven force distribution, difficulty in control, and a high risk of injury to repair workers; large and cumbersome tire trailers are not efficient enough, occupy a lot of space, and lack versatility; tire scooters are large, difficult to control, prone to slipping and loss of balance, and lack sufficient safety and stability. Secondly, currently used tire removal tools are not easily disassembled and assembled, are bulky, occupy a lot of space, and are inconvenient to carry and move for repair work, requiring multiple people to work together during repairs and replacements; furthermore, purely manual operation is time-consuming and labor-intensive, increasing energy consumption and creating certain safety hazards. These problems exist in the repair industry, and from the perspective of overall convenience, repair comfort, and operability, they are issues that require solutions from those skilled in this technical field.

[0033] In this embodiment, a support rod 3 is also included, with the two ends of the support rod 3 connected together by pry bars 1.

[0034] In this embodiment, the two ends of the support rod 3 are welded together with pry bars 1.

[0035] In this embodiment, the length of the chain 5 is adjustable.

[0036] In this embodiment, the movable buckle 7 is welded to the support base 2 for fixed connection, and the movable buckle 7 and the support base 2 are provided with round holes.

[0037] Example 2 like Figures 1 to 3 As shown, the present invention provides a portable auxiliary device for removing tires from a car wheel axle, which includes a pry bar 1, a support base 2, a support rod 3, a rubber pad 4, an iron chain 5, a hook 6, and a movable buckle 7.

[0038] The pry bar 1 is connected to the base of the support seat 2 by a slip-fitting method. The pry bar 1 can be separated for independent operation or used as an auxiliary lever to apply force for tire removal. The support seat 2 has a rubber pad 4 on its surface, which is fixed by adhesive or rivets. Its main function is to increase the frictional resistance with the center fulcrum of the wheel axle and increase the force-bearing area. The support rod 3 is welded to the base of the support seat 2. Its main function is to transfer the force on the large area of ​​the support seat 2 to the pry bar 1 to assist in the lever removal of the tire. The movable buckle 7 is welded to the support seat 2 with a face-to-face connection. The iron chain 5 inside the movable buckle 7 can rotate 360°. It can pull up, down, left, and right to assist in removal from all directions and at different angles depending on the tire position. Its main function is to act as a bridge hub, welding the iron chain 5 to the hook 6. This is the most critical link and the key step to remove the tire smoothly and steadily. The support seat 2 and the iron chain 5 can be adjusted at any time according to the area of ​​the wheel axle bushing, the tire hole, and its size and position.
