A tool for anchoring a housing barrel where in the barrel has a plurality of expandable claws, the tool comprising a support plate moveable axially and a plunger associated with the plate moveable therewith. The plunger has a plate engaging in and a tapered point. The tapered point is arranged to cooperate with an expansion tool consisting of a bowl cage, and a number of balls arranged around the cage periphery. Each ball is brought opposite the claw it is to deform. When the tapering point of the plunger penetrates the ball cage, the bails are displaced radially outward and thus deform the claws radially outwardly in the hole of the door section. |
