Patent attributes
A rivet fixing device includes a catch tab retainer tube engageable with a transmission spindle of an electrically-operated, pneumatic or battery-powered electric drill or screwdriver, an inner guide sleeve, a driver, pawls, a rivet breaker, and an outer guide sleeve. By being driven by the transmission structure of the electric screwdriver, a rivet, with a shank section thereof inserted into a front end of the rivet breaker and the rivet being fit through holes defined in steel plates, iron plates, copper plates, or aluminum plates, due to the catch tab retainer tube being depressed inward to engage the transmission spindle, is driven by the rearward movement of the catch tab retainer tube to have a fit end thereof that extends beyond the holes of the plates squeezed and deformed to form an expanded portion, serving as a positioning wall that stretches and secures the rivet between the two metal plates.
