[0030] Furthermore, a regulating valve 203 is installed on the top of the oxygen cylinder 201, and the air inlet end of the regulating valve 203 is connected to the air outlet end of the oxygen cylinder 201.

[0031] Furthermore, a handle 205 is fixedly connected to the top of the surface of the oxygen cylinder 201.

[0032] Through the coordinated use of the protection mechanism 1 and the oxygen storage mechanism 2, oxygen can be easily supplied to patients who need emergency treatment. The oxygen cylinder 201 is placed in the limiting ring 102, and the limiting ring 102 limits the oxygen cylinder 201. The base 101, the cover 105 and the top plate 103 protect the multiple oxygen storage mechanisms 2 to prevent the oxygen storage mechanisms 2 from being damaged by collision. When the oxygen storage mechanism 2 needs to be taken out, the limiting mechanism 3 on the oxygen storage mechanism 2 is released, and the oxygen storage mechanism 2 is taken out through the taking-out hole 104 at the top of the top plate 103. By arranging a handle 205 on the top of the oxygen cylinder 201, it is convenient for the user to take the oxygen cylinder 201, install the oxygen tube and the breathing mask on the regulating valve 203, and open the regulating valve 203 to discharge the oxygen stored in the oxygen cylinder 201 to provide emergency oxygen supply to the patient.

[0033] Furthermore, the limiting mechanism 3 includes a pull rod 301, the bottom of the pull rod 301 is fixedly connected to a multi-head fixed plate 302, the surface of the multi-head fixed plate 302 is fixedly connected to a number of pins 309, the pins 309 pass through the socket 204 to fix the mounting frame 202, the bottom of the multi-head fixed plate 302 is fixedly connected to a lifting rod 303, the bottom of the lifting rod 303 passes through the bottom of the base 101, the bottom fixed sleeve of the surface of the lifting rod 303 is provided with a sliding seat 306, the inside of the sliding seat 306 is slidably connected to a sliding rod 305, the top fixed sleeve of the sliding rod 305 is provided with a connecting piece 307, the top of the connecting piece 307 is fixedly connected to a limiting rod 311, and the movable sleeve on the surface of the limiting rod 311 is provided with a spring 304 and a fixing frame 308.
