The trapezoidal rod 205 is slidably connected inside the top ring 203. The trapezoidal rod 205 is movably inserted into the side wall of the fixing rod 202. The movable ring 204 is slidably connected to the top of the trapezoidal rod 205. By providing the fixing structure 2 between the valve 1 and the adjusting mechanism 101, it is convenient to quickly disassemble and assemble the valve 1 and the adjusting mechanism 101, avoiding the time-consuming and laborious situation of the current process of sequentially rotating nuts for disassembly and assembly.

[0028] The bottom of the fixed rod 202 is fixedly connected with a bottom ring 201, and the bottom ring 201 is sleeved on the top side of the valve 1.
