DEVICE FOR IMMOBILIZING AN OUTER FIRST TUBE AND AN INNER SECOND TUBE OR A SOLID ROD WHICH ARE MOUNTED TELESCOPICALLY WITH RESPECT TO ONE ANOTHER

摘要

The subject of the invention is a device for immobilizing an outer first tube T1 and an inner second tube T2 which are mounted telescopically with respect to one another, which device comprises: lateral traction means LB, articulation means C1, O2 for articulating said lateral traction means between a free position and a locked position, locking means MV for locking said lateral traction means in the locked position thereof, immobilizing means MS: • articulated to a first end of said lateral traction means, • mounted to slide longitudinally relative to the inner tube such that when said lateral traction means are in the locked position, said immobilizing means apply a lateral force to the inner tube capable of causing the inner and outer tubes to be immobilized.
