The gas enters the inside of the cylinder body 16 through the air inlet 13. The movement of the piston 14 will gradually reduce the space volume inside the cylinder body 16, resulting in the compression of the gas inside the cylinder body 16. Pull back the operation tube 17 to make the piston 14 move backward, thereby releasing the pressure inside the cylinder body 16.

Gas enters the inside of the cylinder body 16 through the air inlet 13. The movement of the piston 14 will gradually reduce the space volume inside the cylinder body 16, causing the gas inside the cylinder body 16 to be compressed. Pull back the operation tube 17 to make the piston 14 move backward, thereby releasing the pressure inside the cylinder body 16.
