Supporting structure of electric trolley

A supporting structure of an electric trolley comprises a pair of installation panels which are arranged in parallel and vertically installed and supporting pieces used for installing the installation panels on a rack, each supporting piece comprises a bottom supporting part and side edge limiting parts, the number of the supporting pieces is at least two, and the side edge limiting parts with different limiting distances are formed; the potential difference generated by inclination of the side pipe is counteracted. The side edge limiting parts abut against the inclined side pipes, due to the fact that the limiting distances of the side edge limiting parts are different, potential difference generated by inclination of the side pipes is counteracted, the installation panel is vertical and perpendicular to an axle of a front wheel, the brake caliper can be directly installed on the installation panel, and therefore the effect that the brake caliper is convenient and fast to install is achieved. 一种电动手推车的支撑结构，包括
