Abstract

The present disclosure provides an apparatus and method of combining pliers and tubing cutters. The resulting tools offers synergistic results that are unachievable with separate tools. In at least one embodiment, the tubing cutter pliers can be operated by rotating the pliers'"'"' handles, cutting the tubing with a cutter wheel on the pliers, and gripping the tubing using the same pliers as was used to cut the tubing. Some intervening steps, particularly, removal of the tubing cutter and replacement of the tubing cutter with pliers, can be eliminated with a resultant increase in efficiency and productivity. In some embodiments, an adjusting mechanism can be provided to offer increased control over the amount of pressure exerted on the tubing by the tubing cutter pliers during the cutting process.

Claims

1. A tubing cutter pliers, comprising:

a first handle coupled to a first jaw, the first jaw having a gripping surface;

a second handle coupled to a second jaw, the second jaw having a gripping surface, and the second handle being rotatably coupled to the first handle so that an object can be held between the first and second jaws; and

at least one cutter wheel coupled to at least one of the jaws.

2. The pliers of claim 1, further comprising at least one cutter roller coupled to a jaw opposite from the jaw to which the cutter wheel is coupled.

3. The pliers of claim 2, further comprising at least two cutter rollers coupled to the opposite jaw and spaced at an angle to each other relative to the cutter wheel.

4. The pliers of claim 1, wherein the cutter wheel is coupled to the jaw at a location adjacent an intersection of the first and second handles.

5. The pliers of claim 1, wherein at least one of the jaws comprises gripping teeth.

6. The pliers of claim 1, further comprising a manually adjustable element coupling the first and second jaws to manually adjust a spacing between the cutter wheel and the jaw opposite from the cutter wheel.

7. The pliers of claim 6, wherein the manually adjustable element comprises a rotatable threaded element adapted to space the first jaw from the second jaw when the cutter wheel is placed in proximity to a tubing to be cut.

8. The pliers of claim 1, wherein the pliers comprises self-adjusting pliers, arc joint pliers, slip joint pliers, and long nose types of pliers having the cutter wheel coupled thereto.

9. The pliers of claim 1, wherein the cutter wheel is adapted to engage a tubing disposed adjacent thereto by movement of at least one of the jaws.

10. A method of cutting and gripping a tubing, comprising:

placing a pliers having a cutter wheel and jaws over the tubing;

cutting the tubing with a cutter wheel on the pliers; and

gripping the tubing with gripping surfaces on the jaws of the pliers.

11. The method of claim 10, wherein cutting the tubing with the cutter wheel on the pliers comprises moving the jaws to cause the cutter wheel to engage the tubing and rotating the pliers relative to the tubing to cut the tubing.

12. The method of claim 11, further comprising moving the jaws to position the tubing away from the cutter wheel and moving the jaws in an opposite direction to grip the tubing between the jaws without engaging the tubing with the cutter wheel.

13. The method of claim 10, further comprising manually adjusting a spacing of the jaws by rotating a threaded element coupled between the jaws.

14. The method of claim 13, wherein the rotating the threaded element comprises adjusting a spacing of the cutter wheel.
