Lifting table 4

To get a higher position: lift the green table to a desired position.
To get a lower position:
1. Lift the table to the highest position
2. Lower it to the lowest position
3. Lift it to a desired position.
The black springs always force the pink pawls toward the beige racks.
At the highest position of the table, thanks to the highest teeth of the racks, the flat springs begin to prevent the pawls from contacting the racks.
At the lowest position of the table, the S red stoppers raise the flat springs to release the pawls.
