the buffer air bag 31 to cause the buffer air bag 31 to swell, when the buffer air bag 31 swells, the swollen buffer air bag 31 needs to be compressed when the first block 5 and the second block 6 are folded again (it needs to be pointed out here that when the buffer air bag 31 swells completely, the first block 5 and the second block 6 are folded for a certain angle, the air inside the extrusion
