The first storage assembly 41 extends in the width direction of the frame structure 300, and exceeds the edges of the first support frame 42 on both sides of the width direction of the frame structure 300. In this embodiment, the length direction can be the first direction X, and the width direction can be the second direction Y. In this embodiment, the length of the first storage assembly 41 in the width direction of the frame structure 300 is greater than the length of the first support frame 42 in the width direction of the frame structure 300.
