摘要：
A folding cart includes a tray, a chassis frame and a plurality of independent and foldable support frames. Each support frame has a first support member and a second support member with ends pivotally coupled with each other. The other ends of the first support member and the second support member have pivot member for pivotally coupling pivoting portions of the tray and the chassis frame respectively, so that the tray, the chassis frame and the support frames jointly form an accommodating space. When the support frames are folded, the pivotally coupled ends of the first support member and the second support member are accommodated in the accommodating space. The first support member and the second support member are pivotally coupled by a special pivoting structure for adjusting the height of the folding cart, and the folding cart further has a moving element for moving the folding cart.
