Hood for confinement and handling of at least two objects of slender shape, including: - an external first enclosure extending along a longitudinal axis X', including a cover, a bottom provided with an opening and a valve for blocking the opening and thereby sealing the external enclosure; - a second enclosure forming a barrel, extending along the axis X' and guided in rotation about the axis X' inside the external enclosure; - at least one internal third enclosure and one internal fourth enclosure each extending along a longitudinal axis X1, X2 parallel to the axis X' and each adapted to accommodate an object of elongate shape, the at least two internal enclosures being fastened to each other and guided in translation in the barrel over a stroke A0; each internal enclosure (82A, 82B) including within it: • a holding member adapted to pick up an object of elongate shape; • a screw-nut mechanism (9A, 9B) consisting of a lead screw (90A, 90B) guided in rotation about the axis X1, X2 and a nut (91A, 91B) around the screw and to which the holding member is fastened, the mechanism being adapted to guide the latter in translation in the internal enclosure over a stroke A greater than the stroke A0; • a bottom (801A, 801B) including an opening (802A, 802B) opposite the holding member to allow an object picked up thereby to pass through; the hood further including: - at least one motor (83A, 83B) fixed above an internal enclosure and inside the barrel, the motor(s) being adapted to rotate the screw of the screw-nut mechanism of each internal enclosure and therefore the nut over the stroke A; - mechanical control means arranged in part above the cover of the external enclosure for manually guiding the internal enclosures in translation over the stroke A0; - mechanical control means arranged in part above the cover of the external enclosure for manually pivoting the barrel in order to bring a holding member of one of the internal enclosures opposite the opening in the bottom of the external enclosure. - an external first enclosure extending along a longitudinal axis X', including a cover, a bottom provided with an opening and a valve for blocking the opening and thereby sealing the external enclosure; - a second enclosure forming a barrel, extending along the axis X' and guided in rotation about the axis X' inside the external enclosure; - at least one internal third enclosure and one internal fourth enclosure each extending along a longitudinal axis X1, X2 parallel to the axis X' and each adapted to accommodate an object of elongate shape, the at least two internal enclosures being fastened to each other and guided in translation in the barrel over a stroke A0; • a holding member adapted to pick up an object of elongate shape; • a screw-nut mechanism (9A, 9B) consisting of a lead screw (90A, 90B) guided in rotation about the axis X1, X2 and a nut (91A, 91B) around the screw and to which the holding member is fastened, the mechanism being adapted to guide the latter in translation in the internal enclosure over a stroke A greater than the stroke A0; • a bottom (801A, 801B) including an opening (802A, 802B) opposite the holding member to allow an object picked up thereby to pass through; - at least one motor (83A, 83B) fixed above an internal enclosure and inside the barrel, the motor(s) being adapted to rotate the screw of the screw-nut mechanism of each internal enclosure and therefore the nut over the stroke A; - mechanical control means arranged in part above the cover of the external enclosure for manually guiding the internal enclosures in translation over the stroke A0; - mechanical control means arranged in part above the cover of the external enclosure for manually pivoting the barrel in order to bring a holding member of one of the internal enclosures opposite the opening in the bottom of the external enclosure.
