The invention relates to a sampling tool (1'), characterised in that same includes: a guiding body (1) provided with a through bore (10); a part-carrying punch (2) mounted slidingly adjustable in the bore (10), comprising a lower edge (20), forming a cutting edge; a part-carrying die (3) separated from the guiding body (1) by an opening (4), being provided with a through bore (30) which the lower end (20) of the punch (2) enters when cutting of the sample to be collected, and being provided with a cutting upper edge; a means for actuating the punch (2) between an initial position, in which said punch is retracted into the body (1), a stationary intermediate position, in which the punch is positioned by the edge (20) thereof in the bore (30), and a final position in which the punch passes through the die (3) from one side to the other, the lower edge thereof being outside of the bore (30). The path of the punch (2) is tangential to the surface (310) of the opening (4) and the bore (30) is tangential to a geometric plane containing said surface (310) in order to make a cut with an open contour in the plant from which the sample is collected. |
