Description

Technical Field

[0001] The invention relates to the technical field of roller skating auxiliary equipment, in particular to a multifunctional roller skating aid with a transformable combined structure. Background Art

[0002] Roller skating and ice skating are fashionable and healthy sports. Ice skating can not only exercise and enhance the body's balance, coordination and flexibility, but also enhance the cardiopulmonary function and improve aerobic exercise capacity. It can also effectively exercise the lower limb strength. However, when first learning these two sports, many people will fall due to unstable center of gravity or slipping feet, which affects the experience.

[0003] However, the existing roller skating learning aids have relatively simple structures and functions, and cannot be flexibly combined and transformed according to the needs of use, which leads to certain limitations in the actual use process. Moreover, since roller skating is easy to learn, the learning aid is no longer needed after learning to skate independently. In this way, the learning aid will be idle. The idle learning aid not only takes up space, but also cannot be used in daily life, thus causing unnecessary waste. Summary of the Invention
