PROBLEM TO BE SOLVED: To provide an economical rivet setting tool with a simpler construction used with double headed rivets. SOLUTION: A rivet setting tool used with double headed blind rivets comprises a collet assembly 17 adapted to engage a pulling head 10 of a mandrel 6 of rivet 2, and a supporting segment 38 for engaging the rivet. A single piston- driving device pulls the collet assembly 17 and the mandrel 6 backward with respect to the supporting segment 38 and the rivet 2 to set the rivet. A continued movement of the piston 19 further retracts the collet assembly 17 and the supporting segment 38 to permit delivery of a new rivet in front of the tool and returns the collet assembly and the supporting segment to a forward position in engagement, respectively, with the head of the mandrel 6 and the rivet 2. |
