When the rotating shaft 3 is matched with the connecting part 2, the protruding part of the convex ring 203 is arranged in the first notch 204, the second through hole 208 is ensured to be coincided with the first through hole 207, the rotating shaft 3 sequentially penetrates through the second through hole 208 and the first through hole 207, and then the device for realizing the linear displacement of the valve core can be assembled. Further, a stopper protrusion 209 is provided on an outer wall of the rotation groove 202, and the stopper protrusion 209 is integrally formed with the rotation groove 202.

The spindle 3 comprises a spindle body 301 and a handle portion 302, wherein the spindle body 301 and the handle portion 302 are integrally formed. The joint of the rotating shaft body 301 and the handle part 302 is movably connected with a limiting fixed block, and a limiting block 303 is fixedly arranged on the limiting fixed block.
