As an example, the flat rotary connecting column 3 in the present utility model may be a structure in which two chords of a cylinder parallel to each other on both sides of a diameter are each formed by removing an arcuate body.
The liftable connecting assembly is characterized in that the flat rotary connecting upright post 3 with the plane 31 and the arc-shaped surface 32 is arranged, and the fixed seat 5 is arranged on the flat rotary connecting upright post 3 through the opening bush 6. When the height of the fixed seat 5 needs to be adjusted, the arc-shaped surface 32 of the flat rotary connecting upright post 3 is rotated to the opening 61 by using the rotary handle 4, and the distance between the planes 31 on two opposite sides is smaller than the inner diameter of the opening bush 6, and the width of the opening 61 is greater than or equal to the width of the arc-shaped surface 32, the arc-shaped surface 32 of the flat rotary connecting upright post 3 is not contacted with the inner wall of the opening bush 6, so that the opening bush 6 can drive the fixed seat 5 to slide along the length direction of the flat rotary connecting upright post 3, so as to adjust the height of the fixed seat 5.
