A file box containing device is used for achieving storage of electric materials and brings convenience to accessing of corresponding materials as needed. The file box containing device comprises a base, a support, supporting rods, storage bins, a poking assembly and a lifting and horizontal moving assembly. The support is arranged on the top of the base. The multiple storage bins are arranged on the upper portion of the support. A guide rail is fixed to the rear side of each storage bin. A movable block is installed outside each guide rail in a sliding mode. A sliding rod is installed in an inner cavity of each guide rail in a sliding mode. A spring is arranged between each movable block and the corresponding guide rail. The two sides of the support are each provided with one supporting rod, and the poking assembly driving the sliding rods to slide is arranged between the two supporting rods. The base is provided with the lifting and horizontal moving assembly, and the lifting and horizontal moving assembly and a chain transmission drive the poking assembly to act. A computer is controlled by an operator to enable the lifting and horizontal moving assembly and the poking assembly to be matched for acting, so that a corresponding file box is pushed out of the corresponding storage bin, and workloads generated when the operator directly searches for materials are greatly relieved.
