Description

Technical Field

[0001] The utility model relates to the technical field of logistics transportation, and more specifically, to a transport scooter with a flexible steering function. Background Art

[0002] A cart is a transport vehicle that is pushed and pulled manually; it can be one-wheeled, two-wheeled, three-wheeled, or four-wheeled. A one-wheeled cart can navigate narrow gangplanks, temporary bridges, and narrow paths, and can turn on the spot, making it very convenient for unloading. Common two-wheeled carts include push carts (also known as tiger carts) for transporting piece goods, rack carts, and bucket carts for transporting bulk materials. Three-wheeled carts have one, while four-wheeled carts have two swivel casters that can pivot about a vertical axis (see the swivel caster figure).
