The invention discloses a multi-link roller base which comprises a main body and wheels arranged on the main body. The main body is composed of a plurality of links , the wheels are arranged on link assemblies; each link assembly comprises a middle link and an end link, the two sides of the middle link are provided with rotation connection sites, one side of the end link is provided with a rotation connection site, the rotation connection sites of the adjacent links realize the rotation connection through a connection device. The multi-link roller base provided by the invention has the following advantages: by providing the multi-link roller base which can be connected in serials, the links can be randomly and serially connected, the roller bases with different lengths can be assembled according to needs, and a unique joint design of the link assemblies enables each link to have good rotational freedom in different directions. During use, each wheel has good plasticity, good sufferingand shock adsorption effect and high stability, and can ensure the comfort advancing in the uneven road.
