Tool for handling a cluster of rods of consumable poison

Tool for handling a cluster of rods of consumable poison, said tool comprising a head for gripping the cluster, connected to the end of a handling member displaceable slidably in a tool body between an active position in which the head and at least part of the member project from the body, and a retracted position in which the gripping head, the handling member and at least part of the cluster extend within the body, and combs for guiding the rods, provided at the corresponding end of the body and displaceable by raising between a retracted position in which said combs extend substantially along the wall of the body, and an active position in which said combs extend substantially perpendicularly to said wall, in order to guide the rods, wherein said tool comprises elastic means for stressing said combs into active position and means for retracting said combs counter to the stress of said elastic means, displaceable between an active position of retraction of said combs and a retracted position of release of said combs by said gripping head and/or said handling member during displacement between their active position and their position retracted within said body.
