Abstract: PURPOSE: To simplify the structure of a blind rivet setting tool by pulling a head and setting the rivet while restraining the rivet by engaging a rivet head therewith. CONSTITUTION: The assembly 53 of the double head rivet setting tool having the collet assembly of the structure engaging the pull head of the rivet and the abutment assembly 53 is movable between a release position where the pull head of a mandrel 6 of the rivet passes the abutment assembly 53 and the collet assembly engages the same and a closed position where the assembly comes into contact with the rivet head and engages the same. When abutment members 54 are mounted and the double headed blind rivet is presented, the head of the rivet engages the abutment members 54 and when the rivet head is pressed to the tool, the abutment members 54 are securely closed around the mandrel 6. As a result, the cost effective tool of the simple structure may be obtained.
