Referring to fig. 3, the three-way joint further includes a fixing member 3. The fixing member 3 includes a fixing block 31 and a spring 32. The fixing block 31 is disposed on an outer wall of the mounting ring 221. The opening of the auxiliary pipe joint 21 is provided with a vertical groove 211 for the fixed block 31 to slide, and the vertical groove 211 is arranged along the length direction of the auxiliary pipe joint 21. The inner peripheral wall of the sub pipe joint 21 is provided with a transverse groove 212 for the fixed block 31 to slide in, the transverse groove 212 is arranged along the circumferential direction of the inner wall of the sub pipe joint 21, and the transverse groove 212 is vertical to and communicated with the vertical groove 211. The horizontal grooves 212 and the vertical grooves 211 combine to form L-shaped grooves. The inside wall cass of the sub pipe joint 21 and the positioning groove 213 for the fixed block 31 to slide in are arranged along the length direction of the sub pipe joint 21, the positioning groove 213 and the transverse groove 212 are mutually vertical and communicated, and the positioning groove 213 and the vertical groove 211 are positioned on the same side of the transverse groove 212. In the present embodiment, the fixing block 31 and the mounting ring 221 are integrally formed.

Referring to fig. 3 and 4, the inner wall of the sub pipe joint 21 is coaxially provided with an abutment ring 214. The abutting ring 214 has a first circular groove 2141 coaxially formed at an end thereof close to the mounting ring 221, and the mounting ring 221 has a second circular groove 2211 coaxially formed at an end thereof close to the abutting ring 214.
