Abstract: A stroller (100) includes a frame (1), a handrail (2) and a dinner plate (3). The handrail (2) is installed on the frame (1) and located in front of the frame (1), and the dinner plate (3) is detachably connected with the handrail (2). With detachable connection of the dinner plate (3) and the handrail (2), the dinner plate (3) and the handrail (2) can work independently or together. When the dinner plate (3) is connected to the handrail (2), the stroller (100) has safety and feeding convenience. When the dinner plate (3) is removed from the handrail (2), the handrail (2) still can work, thus ensuring the safety of the stroller (100). It is convenient to remove the dinner plate (3) for cleaning at any time, thereby reducing difficulty of cleaning the dinner plate (3), and the replaceable dinner plate (3) can reduce maintenance cost. Therefore, the stroller (100) has the advantages of simple structure, and that the handrail (2) and the dinner plate (3) can work independently.
