The polygonal design can also evenly distribute pressure and reduce local wear.

[0037] In this embodiment, when it is necessary to fill argon into the hollow glass, first, the connecting pipes 13 at both ends of the gas inlet pipe 3 and the gas outlet pipe 4 are connected with the external filling device and the air extraction device.

[0039] More specifically, when the adjusting sleeve 6 rotates, the positioning block 22 tries to enter the positioning groove 21 on the outside of the outer sleeve 5 under the action of the push spring 23. Once the positioning block 22 enters the positioning groove 21, the position of the adjusting sleeve 6 is fixed, thereby achieving accurate control of the gas flow. If it is necessary to adjust the position, it is only necessary to exert sufficient force to overcome the pressure of the push spring 23 to make the positioning block 22 disengage from the positioning groove 21, so as to re-adjust the position of the adjusting sleeve 6.
