An oxygen mother bottle is fixedly installed at the top end of the rotating mechanism. A quick clamping mechanism is arranged at the top end of the workbench. The quick clamping mechanism includes a transmission mechanism and a clamping mechanism. By starting the second motor, when the second motor drives a rotating rod to rotate, it will simultaneously drive the other three rotating rods and sprockets to rotate. At this time, the arc-shaped clamping plates will move towards the direction of the fixed plate. At this time, the relative distance between each pair of arc-shaped clamping plates on the side end of the fixed plate becomes closer and closer. At this time, four oxygen empty bottles will be clamped and fixed simultaneously, without the need to fix each oxygen empty bottle one by one. The fixed method of the oxygen empty bottles becomes simple through electric fixing, so that a large amount of fixing and installation time will not be consumed, and the work efficiency is improved.
