1. A device for handling inner tubes (A) of a perforation string, which allows preparing said inner tubes for the extraction of a sample, reducing the intervention of operators, reducing risks and facilitating the handling of the inner tube, optimizing work times and improving the efficiency of the operation, where the inner tubes (A) include a head at one end that allows access to the sample, comprising:
an elongated supporting structure that receives and supports the inner tubes (A), so that the inner tubes (A) and the supporting structure are parallel in their axial direction, wherein said supporting structure comprises at least one pivoting mobile support;
an adjustable extension, at one of the ends of the supporting structure, which receives the inner tubes (A), being a pivoting element, so that its angle can be varied to adapt to different reception angles of the inner tubes (A);
a sliding assembly on the supporting structure and that can move along it, comprising means to hold the inner tube (A) when it is received by the adjustable extension and allows the tube (A) to be positioned interior on the supporting structure;
at least one transfer arm pivoting to one side of the supporting structure and aligned with the at least one mobile support, so that the at least one transfer arm pivots to receive the inner tube from the at least one mobile support; and
a cutting press adjacent to said at least one transfer arm so that it can hold the inner tube (A) to unscrew the head of the inner tube (A).
