Claim:
A gripping device comprising: a cylindrical thorn presenting a tapered part, an inner body, an outer body with a plurality of movable arms, each of said arms including a claw, the thorn and the inner body being directly coupled to one another with the thorn extending through the outer body, a spring positioned in between the inner body and the outer body and adapted to push the arms to a first gripping position, an arm spring placed around said plurality of arms in order to pull the arms towards the thorn, and wherein the gripping device is adapted to set the arms in a plurality of other gripping positions by moving the inner body and the outer body relative to each other along a symmetry axis through the inner body and the outer body with the tapered part of the cylindrical thorn allowing the movable arms to slide about the cylindrical thorn to move in a direction towards the symmetry axis thereby reducing an outer diameter of the gripping device.
