How does the stool rise and fall?

The lifting mechanism of a round stool is usually realized by adjusting the high pitch with a cylinder.

There will be an adjusting handle on the base of the stool to control the lifting of the cylinder. When the stool needs to be raised, make sure that no one is sitting on it, then move the adjusting handle to push it up, and the cylinder will start to rise, and the height of the stool will increase accordingly. On the other hand, if there are people or heavy objects on the stool surface, move the adjusting handle and pull it down, the air cylinder will go down and the height of the stool will be reduced. Through the lifting mechanism of the cylinder, the height of the round stool can be adjusted conveniently.
