A pneumatic lift apparatus has a main body including a body tube, with a cross-section of the body tube being neither a perfect circle nor a polygon. A restricting device is slidably mounted on the body tube of the main body, with the body tube restricted not to rotate relative to the restricting device. The restricting device is coupled to an end of a housing, with the main body inserted through the restricting device and received in the housing, with the main body fixed in the housing opposite to the restricting device.
