HAND TROLLEY WITH A LOAD TRAY CO-WORKING WITH WHEEL SETS

摘要

A hand trolley with a load tray movably connected with wheel sets includes a handle frame, two wheel sets and a load tray. The handle frame has two pivotal connecting portions used to connect with the wheel sets and the load tray. The wheel set is provided with an acting surface mutually co-working with an acting surface of the load tray. The wheel set can be unfolded as the load tray is pushed down, and it can be folded as the load tray is pulled up. Thus the hand trolley is able to make the load tray and the wheel set folded or unfolded simultaneously, easy to be stowed away.
