I'm watching my daughter on that spring rider.

我在看我女儿骑那个春天的骑手。

Well, a " spring rider" isn't so much about the child moving up and down, but more side to side, I think.

好吧，我认为“弹簧骑手” 并不是关于孩子上下移动，而是左右移动。

To be honest, we didn't have spring riders when I was a child at the playgrounds I used to go to, but I think that's what it is.

老实说，我小时候经常去的游乐场没有春季骑手， 但我认为就是这样。

The important thing in a " spring rider" is that it is attached to or connected to a metal spiral – something made of a very strong, long tube of metal that goes around and around in a circle.

“弹簧骑手”的重要之处在于它附在或连接到金属螺旋上——由非常坚固、长的金属管制成的东西，绕着一圈又一圈地转。
