[0056] The male valve post 25 is provided with a clamping hole 256 which is tangent to the second mounting hole 251 and partially overlaps the second mounting hole 251 at the tangent position. The clamping hole 256 corresponds to the second shaft clamping ring 254. The clamping hole 256 is provided with an opening on the side close to the adapter ring 13. The adapter ring 13 is provided with a receiving groove corresponding to the clamping hole 256 on the side wall. The clamping hole 256 is provided with a clamping post 257.

At this time, the first clamping segment is partially embedded in the receiving groove, which has a certain clamping effect on the rotation of the female ball valve 10 relative to the male ball valve 20, but cannot truly and effectively limit the two. When the female ball valve 10 is closed and the limiting pin 167 is reset, a certain force can be used to rotate the adapter ring 13 relative to the male body 21, thereby disconnecting the two.
