However, the front end of the reciprocating rod 23 is fixed in the range of the buffer chamber 62 with a pressure ring 65 abutting against the front end of the spring N. When the pressure ring 65 is pulled back by the reciprocating rod 23, the rotation limit member 73 is first blocked by the closing limit adjusting member 77. Then, the pressure ring 65 is engaged with the reciprocating rod 23 and then pulled to the piston ring 22 to press the logic driving member 5, so that the piston ring 22 has both the driving swing unit 7 and the control choke valve body A2. In addition, the closing limit adjusting member 77 can also be adjusted, and the position adjusted by the closing limit adjusting member 77 controls the back pulling distance of the splicing lever 67, and adjusts the position of the buffering chamber 62 so that the reciprocating rod 23 is in the buffer chamber. The 62 position is changed to deal with the range of displacement of the piston ring 22, and at the same time, the benefit of the stroke of the logic drive member 5 and the gas barrier washer 51 after being impacted by the piston ring 22 is corrected.
