[0028] A sealing ring 10 is installed at the upper end of the nozzle 7, and docking grooves are provided at both ends of the mounting block. The sealing ring 10 is engaged with the docking grooves to reduce the gap when the nozzle 7 is docked with the docking tube 3 to avoid gas leakage.

[0030] The auxiliary block 6 is provided with an auxiliary hole, and the auxiliary shaft 8 is rotatably connected to the auxiliary hole.
