The adjusting rod 804 extends through the driving disk 803 to the inside of the cover plate 801 and is connected to a closing disk 805. The bottom end surface of the closing disk 805 is connected to the gas outlet 701.

[0027] Furthermore, a through hole 8033 for inserting the adjusting rod 804 is opened in the middle of the driving disk 803, and limiting protrusions 8041 are set on both sides of the upper part of the adjusting rod 804, and the outer diameter of the limiting protrusion 8041 is larger than the inner diameter of the through hole 8033, so that the driving disk 803 limits the downward movement of the adjusting rod 804 through the limiting protrusion 8041.

At this time, the sealing spring 808 elastically stretches, and the closing disk 805 abuts against the air outlet 701 of the inner liner tube 7, thereby blocking the air outlet 701; Step A3, the control valve button 802 is connected to the fixing plate 12 to drive the control magnet 13 to rotate, and the control magnet 13 acts on the Hall element 14 to open the gas output device corresponding to the gas delivery pipe 1 through the Hall switch 15, so as to realize the gas output of the gas delivery pipe 1; Step B, adjusting the gas output of the gas cylinder gas delivery pipe 3; Step B1, reversely rotate the control valve button 802, so that the wedge-shaped guide plate 8021 moves out from the upper end of the connecting column 8031 ​​through the arc-shaped groove 8022, the return spring 809 elastically stretches, and the drive disk 803 moves upward inside the support tube 9 through the vertical groove 901.
