这款音乐盒内部设计了三角凸轮的结构，转动乌龟的上壳，上好发条后，三角凸轮转动可以带动乌龟的四肢和头尾伸缩，小乌龟随着音乐响起，慵懒地伸懒腰。
The triangle cam structure is designed inside this music box. When you turn the turtle's upper shell, the triangle cam rotation can push the turtle's limbs, head and tail to move. The little turtle stretches lazily with the sound of music.
