The invention relates to a linkage folding structure of a child tricycle. The linkage folding structure comprises a base assembly; and a seat plate assembly, a rear wheel support assembly and a headstock front wheel support assembly, which are connected with the base assembly, wherein the headstock front wheel support assembly is connected with the base assembly in a rotating and folding mode, and the base assembly is provided with a transmission shaft assembly connected with the rear wheel support assembly. The transmission shaft assembly is connected with the headstock front wheel support assembly through a headstock connecting piece, and the headstock front wheel support assembly can drive the headstock connecting piece to drive the transmission shaft assembly when being rotated and folded, so that the rear wheel support assembly connected with the transmission shaft assembly is rotated and folded together. According to the child tricycle, the tricycle head connecting piece can be driven by the tricycle head front wheel support assembly, the tricycle head connecting piece drives the rear wheel support assembly connected with the transmission shaft assembly to rotate together so that the tricycle frame can be folded.The child tricycle is small in size after being folded and convenient to carry and store.
