Product Description
The air expansion shaft is a specially designed winding and unwinding shaft. By inflating the air through the inflation handle into the air nozzle, the key bars or plates on the surface of the shaft will protrude, thereby gripping the inner wall of the material roll (such as the paper tube that matches the air expansion shaft). When it is necessary to release the paper tube for unloading, simply press the air core above the air nozzle to release the air and unload the material.
