Abstract
A hand-held rivet nut 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; and 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, and 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.
Claims18
A hand-held rivet nut 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 two handles;
- a driven member connected pivotally to the two 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 head end of the mandrel;
- and
- a threaded shaft mounted on a head 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 and mounted detachably on the driven member;
- and
- a spiral pushing rod assembly mounted in the mounting tube, mounted detachably in a tail end of the mandrel, 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, wherein pushing and pulling the tube body of the spiral pushing rod assembly relative to the mounting tube drive the mandrel, the bushing and the threaded shaft to rotate.
A hand-held rivet nut 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 two handles;
- a driven member connected pivotally to the two 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 head end of the mandrel;
- and
- a threaded shaft mounted on a head end of the bushing;
- and
- a rotational mandrel-driving device mounted detachably on the driven member, mounted detachably in a tail end of the mandrel, being capable of driving the mandrel, the bushing and the threaded shaft to rotate and having:
- a mounting cylinder mounted detachably on the driven member;
- and
- a rotation assembly mounted on the mounting cylinder and having:
- a pintle mounted rotatably in the mounting cylinder;
- and
- a knob mounted securely on a tail end of the pintle, wherein rotating the knob of the rotational mandrel-driving device drives the mandrel, the bushing and the threaded shaft to rotate.
