It includes a pivot plate, an upper front frame rod, and an upper rear frame rod. The front end of the pivot plate is hinged to the upper front frame rod, and the rear end is fixedly connected to the upper rear frame rod. The lower frame includes a lower front frame rod and a lower rear frame rod located at the front and rear positions, respectively, and the lower front and lower rear frame rods are hinged together. The lower rear frame rod includes a sliding seat that slides relative to the rear frame rod. The hinge axis between the front wheel support frame and the pivot plate is coaxial with the hinge axis between the rear wheel support frame and the pivot plate. The first linkage rod is hinged to the sliding seat, the rear wheel support frame, and the handle sequentially from bottom to top. The handle is pivotally connected to the upper rear frame rod, and the lower end of the handle includes a limiting mechanism for restricting the movement of the first linkage rod. Folding is very simple and convenient.
