<p>A compressed gas tank comprises a cylindrical body and mirror plates at the ends of the cylindrical body. A fastening rod puts through the center of the tank longitudinally. A nut is engaged at one end of the rod, such that the tank is pressingly connected with the mirror plates without welding. The tank has a communicating hole at the circumference. A plurality of tanks is supported by support openings of a cylinder block to form a compressed gas apparatus. The communicating hole of the tank communicates with a gas-guiding hole of the cylinder block connected to a gas compressor.</p> |
