The invention provides a cargo expander, belongs to the technical field of mechanical devices and solves the technical problem that existing cargo expanders are high in machining cost and infirm in meshing. The cargo expander comprises an inner pipe, an outer pipe arranged outside the inner pipe in a sleeved manner, and a positioning member, a part of the inner pipe can extend out of the outer pipe, a handle is hinged on the outer pipe, an elongated groove is formed in the inner pipe axially, an elongated tooth row is embedded in the groove, the end of the handle is provided with ratchets which can be meshed with teeth on the elongated tooth row, and the positioning member can lock the handle when the ratchets are meshed with the teeth. The teeth do not punch the inner pipe directly but are arranged on the elongated tooth row which is alone and is embedded in the groove of the inner pipe, so that depth of the teeth can be increased properly, the teeth large in depth can improve stability in meshing of the teeth and the ratchets of the handle, wear of the teeth can be reduced as much as possible in the process of use, and firmness of the elongated tooth row is guaranteed.
