The connection rod is connectedwith a storage groove used for storing an ebony bead. The surface, used for storing the ebony bead, of the storage groove is opposite to the tip of the penetrating column. A booster pump is arranged in the storage groove. Both the connection rod and the supporting column are connected with supporting rods. The lower ends of the supporting rods are connected with a storage box. A filter screen is arranged in the storage groove. An oblique baffle is arranged in the position, at the lower end of the filter screen, inside the storage box. An opening is formed in the position, at the bottom end ofthe baffle, of the outer side face of the storage box. A shielding plate used for shielding the opening is arranged on the opening. A scraper is arranged at the upper end of the baffle and slides along the plane where the baffle is located. The ebony bead threading structure is simple in structure, and convenient to operate and use.
