Abstract
The present disclosure provides a folding cart. The folding cart includes a cart frame assembly, a wheel assembly, and a handrail assembly. The cart frame assembly may include a plurality of sets of support rod assemblies and a base frame hinged to lower ends of the plurality of sets of support rod assemblies. The wheel assembly may be disposed at a lower end of the cart frame assembly to realize movement of the cart frame assembly. The handrail assembly may be disposed on the cart frame assembly. The cart frame assembly may be driven to move through the handrail assembly under an action of an external force. The handrail assembly may be rotatably connected to the cart frame assembly to make the handrail assembly rotate at least on a first plane.
