The invention provides a carrier of a double-blade needle file, belongs to the technical field of medical accessory assembling machines and solves the technical problem that no carrier capable of positioning the double-blade needle file stably and accurately exists in the prior art. The carrier comprises a baseplate, a middle vertical plate and two lateral vertical plates, both the middle vertical plate and the lateral vertical plates are fixedly connected on the upper surface of the baseplate, the middle vertical plate is positioned between the lateral vertical plates and spaced with the same, the upper surface of each lateral vertical plate is an overlapping face for an edge portion of the double-blade needle file to be overlapped, the overlapping faces of the lateral vertical plates are positioned on a same plane, a retaining block which protrudes upwards and can position front-rear position of the double-blade needle file is arranged at each of two ends of each overlapping face, and a positioning structure capable of positioning left-right position of the double-blade needle file is arranged on the carrier. The carrier has the advantages of accuracy and stability in positioning the double-blade needle file.
