平衡车支架Balance bike bracket

小孩子玩的平衡车装不了脚撑，所以制作了一个平衡车的支架用来放置平衡车，适用于轮胎尺寸为12✖1.75的轮子或者比他小的轮子。因为我的a1mini尺寸有限，也做不了更大的了

The balance bike that children play with can't fit foot supports, so a balance bike bracket is made to place the balance bike, which is suitable for wheels with a tire size of 12✖1.75 or wheels smaller than him. Because my A1mini is limited in size, I can't make a bigger one
