[0054] When the table leg 1 is in use, rotate the second hollow rod 102 to move the first pressing member 1064 downward, so that the first expansion member 1063 is no longer pressed. At this time, the frictional force between the first expansion member 1063 and the first hollow rod 101 decreases. Then, the height of the second hollow rod 102 can be adjusted. After the position is adjusted, rotate the second hollow rod 102 in the reverse direction to move the first pressing member 1064 upward, so as to press the first expansion member 1063. At this time, the frictional force between the first expansion member 1063 and the first hollow rod 101 increases, realizing position fixation; when further height adjustment is required, rotate the third hollow rod 103 to move the second pressing member 1074 downward, so that the second expansion member 1073 is no longer pressed.
