[0026] When the staff needs to connect the pipeline with the flow regulator, after inserting the joint structure into the inside of regulator pipeline 1, the inclined surface of circular truncated cone joint 19 contacts the inclined surface of inclined clamping block 13, thereby driving inclined clamping block 13 to move to the both ends in hole groove 11, when one side of circular truncated cone joint 19 passes over the side surface of inclined clamping block 13 close to the side surface of fixed shell 2, the elastic potential energy of spring 12 resets inclined clamping block 13 to the original place, thereby realizing the locking of joint structure, and the widest end edge of circular truncated cone joint 19 is attached to the inner wall of regulator pipeline 1, thereby preventing water from flowing out from the gap of joint structure.
