[0002] When transporting materials, a transfer vehicle is generally required. Especially in the military field, it is usually necessary to transfer materials in a relatively narrow space, and generally independent personnel are required for independent operations. The existing transfer vehicles generally use a relatively large loading plate as a carrier, with rotating wheels provided on the lower side of the loading plate for rolling, and a handrail provided on one side of the loading plate for support, so as to realize the transfer and transportation of materials. However, the transfer vehicle with this structure cannot operate in a narrow space and does not have a lifting and telescoping function. As a result, the carrying, use, and transfer of materials are restricted by space, so it cannot move and operate conveniently. At the same time, it is difficult for a single person to carry out independent operations, not easy to control, and not convenient for operation. Content of the Utility Model
