The linkage rod is connected to the limit plate, so the action of the adjusting block can directly affect the position of the limit plate. The limit shaft in the limit groove enables the limit plate to rotate freely within a certain range. When the linkage rod pushes the limit plate, the limit plate will move according to the set limit groove boundary, thereby limiting the connection and disassembly position of the oxygen tank. The limit groove is designed as a detachable connection, so that the user can quickly and conveniently operate when the oxygen tank needs to be replaced.

[0015] 4. The breathing device is connected to the oxygen delivery tube through a connector to ensure that oxygen is delivered from the oxygen tank to the breathing mask.
