  • Patent number: 9003621
    Abstract: A hand-held rivet nut (rivet bolt) tool has a body, a sleeve, a positioning ring and a mandrel. The body includes a base and a pair of handles. The handles are respectively pivotally connected to two sides of the base. The sleeve is axially movably mounted through the base and includes an annular mounting groove. The positioning ring is seated in the annular mounting groove of the sleeve and includes an inner portion. The mandrel is rotatably mounted through the sleeve and includes an annular positioning groove allowing the inner portion of the positioning ring to engage therewith. The manufacturing process of the holding structure between the mandrel and sleeve is simplified because it only has steps of forming the annular mounting groove and then seating the positioning ring in the annular mounting groove, which increases production efficiency and reduces manufacturing time and costs.
