ABSTRACT:
A hand portable riveter includes a handle pivoted to a casing to move a pull shaft through a transmission mechanism, causing it to set a rivet or rivnut via a riveter tip assembly, wherein the transmission mechanism consists of a pressure bar pivoted about a pivot in the middle and having a front fork stopped around a neck portion on the pull shaft and a rear fork, and a roller mounted on the rear fork by a pin; turning the handle in one direction causes the pressure bar to press the pull shaft downwards; turning the handle in the reversed direction causes the roller turned along the casing to give a pressure to the pressure bar in lifting the pull shaft.
