摘要 |
<p>The tool includes a bearing member (70), a traction assembly (72) of the object (28), movably mounted in a first direction relative to the bearing member (70). It includes a plurality of hooking members (160), mounted radially mobile relative to the traction assembly (72) between a contracted configuration and a deployed configuration. The tool comprises means (164; 166) for keeping each hooking member (160) in its deployed configuration. It includes unlocking means (168; 170) that include an elastic stressing member (202; 222) applied on the holding means (164; 166). The elastic stressing member (202; 222) is capable of being compressed to cause the unlocking of the holding means (164; 166) and the passage of the hooking members (160) from their deployed configuration to their contracted configuration.</p> |
