Abstract

The invention relates to a linear actuator (100) for moving first (10a) and second (10b) members relative to a fixed member (102), that comprises a base (101) to be connected to the fixed member (102), and that comprises at least one means (102) for rotating a first shaft (103) capable of driving in translation a first rotationally-blocked rod (104), characterised in that the first rod bears a second shaft (113) removably connected to a rotation driving means (112), the second shaft being capable of driving in translation a second rotationally-blocked rod (114).
