[0003] When beginners practice roller skating, it is not safe enough to simply wear protective gear. They are also prone to injuries when they fall, and even fractures in serious cases. Many beginners are afraid to learn roller skating because of fear.

[0004] At present, some auxiliary supports for practicing roller skating have appeared on the market. The user stands in the auxiliary support and slides with his hands on the support, which plays a certain role in safety. In response, the user's hand will break away from the auxiliary bracket, which will cause the auxiliary bracket to lose its auxiliary support function, and the user will collide with the auxiliary bracket after turning over, causing secondary injuries; The height of the bracket is relatively fixed, which cannot meet the needs of some users and reduces the scope of application. If auxiliary brackets with various height specifications are made, the cost of use will be greatly increased
