Claim:
A blind rivet setting tool comprising: a hollow nose for receiving the shank of a mandrel of a blind rivet at a tip of the nose; means arranged inside the nose for gripping the shank of the mandrel received inside the nose; and a piston-cylinder device arranged in a housing behind the nose and actuated by a trigger lever attached to the housing to pull the gripping means rearwardly of the nose, wherein the pulling of the gripping means deforms and expands a portion of a sleeve of a body of the rivet to fasten the rivet body to the workpiece by means of the expansion-deformed portion of the sleeve and a flange on an end of the sleeve, wherein the tool has a handle gripped by an operator that has a tubular configuration surrounding a portion of the housing and arranged to move lengthwise of the housing, wherein the handle is biased away from the nose by a spring, wherein in a standby state the trigger lever is locked against operation by a protrusion on the handle, and wherein the handle can be moved to unlock the trigger lever when the handle is gripped and moved toward the nose after the sleeve of the blind rivet at the tip of the nose is inserted into a hole in a workpiece and the flange is pressed against the workpiece.
