Abstract
A hand-held rivet nut (rivet bolt) tool has a body having a base; two handles connected pivotally to the base; two pairs of links connected pivotally and respectively to the handles; a driven member connected pivotally to the pairs of the links; a mandrel mounted rotatably through the driven member and the base. A push-and-pull mandrel-driving device or a rotational mandrel-driving device is mounted detachably and hence replaceably on the driven member, is capable of driving the mandrel, the bushing and the threaded shaft. A user is allowed to choose either the push-and-pull mandrel-driving device or the rotational mandrel-driving device according to different working spaces or personal practices.

A hand-held rivet nut (rivet bolt) tool comprising:
- a body having
- a base having a through hole defined through the base;
- two handles connected pivotally and respectively to two opposite sides of the base;
- two pairs of links connected pivotally and respectively to the handles;
- a driven member connected pivotally to the pairs of the links, located under the base and having an aperture defined through the driven member and corresponding to the through hole of the base;
- a mandrel mounted rotatably through the aperture of the driven member and the through hole of the base;
- a bushing mounted on a top end of the mandrel;
- and
- a threaded shaft mounted on a top end of the bushing;
- and
- a push-and-pull mandrel-driving device mounted detachably on the driven member and having
- a mounting tube being hollow, mounted detachably on the driven member;
- and
- a spiral pushing rod assembly mounted in the mounting tube, being capable of driving the mandrel, the bushing and the threaded shaft to rotate and having
- a tube body being hollow and mounted in the mounting tube;
- and
- a spiral rod mounted in the tube body.
