Abstract

The tweezers comprises two branches joined at a first end, a second end of each branch comprising a gripping element. The gripping element of each branch is mounted rotating freely around a swivel axis at the second end of said branch. The gripping element of each branch comprises a longitudinal axis perpendicular to the corresponding swivel axis, and a pad is fixed to a free end of said gripping element perpendicularly to said longitudinal axis of the gripping element.

Claims

1. A pair of tweezers comprising:

two branches joined at a first end,

a second end of each branch comprising a gripping element, said gripping element of each branch being mounted rotating freely around a swivel axis at the second end of said branch, wherein

the gripping element of each branch comprises a longitudinal axis perpendicular to the corresponding swivel axis, and a pad is fixed to a free end of said gripping element perpendicularly to said longitudinal axis of the gripping element, and

the pad comprises a rod parallel to the longitudinal axis of the gripping element, sunk into a corresponding cavity of the gripping element, said gripping element being provided with a hole opening out into said cavity, said hole being threaded and having an axis perpendicular to said rod enabling the pad to be fixed by means of a screw screwed into said hole, exerting a pressure on the rod.

2. The tweezers according to claim 1, wherein the gripping element or the pad is removable.

3. The tweezers according to claim 1, wherein the pads are made from materials chosen Delrin, ABS, Polystyrene, or Polypropylene charged with carbon.

4. The tweezers according to claim 1, comprising locking means for locking the distance separating the gripping elements.

5. The tweezers according to claim 4, wherein the locking means comprises a ring in which the branches of the tweezers are inserted.

6. The tweezers according to claim 4, wherein the locking means comprise a cap coaxial to a main body and free in translation in the main body, said main body comprising a locking mechanism to block the cap in the retracted position in the main body when the travel of the cap reaches a predefined threshold, the end of the main body opposite the cap being securedly attached to one of branches of the tweezers and the free end of the cap being securedly attached to the other branch.

7. The tweezers according to claim 1, wherein each pad is mobile in rotation along the longitudinal axis of the gripping element.
