Abstract
The pram includes frame, front wheel assembly, and back wheel assembly. The frame includes front wheel holder, back wheel holder and push handle; the front wheel assembly is set in the lower front part of the front wheel holder; and the back wheel assembly is set in the lower back part of the back wheel holder. The front wheel holder has back end connected to the front end of the back wheel holder, and the back wheel holder has the front end connected to the front end of the push handle in rotation mode. There are one first toothed part with several teeth fixed to the back end of the front wheel holder and one back toothed part with several teeth fixed to front end of the push handle and meshed to the first one. When the frame is expanded or folded, the second toothed part drives the first one to expand or fold the front wheel holder. The pram has less rods and less rod interference.
