Abstract
The present invention provides a pushcart having a rotatable push bar disposed between a first support strut and a second support strut as well as a plurality of braking assemblies connecting to the push bar. By applying a force on the push bar, the braking assemblies release wheels disposed below a base plate, thereby moving the pushcart. On the contrary, by releasing the push bar, the braking assemblies stop the wheels, thereby stopping the pushcart. When not using the pushcart, the push bar and the base plate are folded and stored, thereby saving storage space and enhancing convenience.
