[0063] The top of the upper shell section 111 is sealed by the end cover 113, and the first servo cylinder 12 passes through the through hole in the end cover 113 to be connected with the first connecting part 3. The bottom edge of the lower shell section 112 can extend circumferentially to form a flange. When the liftable column 1 is moved to the position, the second servo cylinder 13 drives the magnetic base 14 to move downward until the magnetic base 14 is at the same height as the bottom flange of the lower shell section 112. The flange increases the contact area with the support surface, so that the liftable column 1 can stably stand on the measurement platform after moving to the position.
