<p>Two lever arms are connected to a collet receiving guide sleeve of a threaded mandrel. The lever arms are connected through a pair of links to a drive element on the sleeve. On compression of the lever arms the drive element pulls the mandrel, which is within bores in the guide sleeve and drive element downwardly and sets a blind rivet which is screwed onto the mandrel, with the rivet engaging the front face of an end cap threaded on the guide sleeve. A rotating device on the drive element rotates the mandrel to screw the rivets.</p> |
