For details, please refer to Figure 1 and Figure 2 The three-way connector 100 includes a three-way body 110 and a valve core 120. The side of the three-way body 110 is fixedly provided with a first interface 111, a second interface 112 and a third interface 113 located in the same horizontal plane. The interfaces of the first interface 111 and the second interface 112 are provided with external threads 115. The top surface of the three-way body 110 is also provided with a first groove 114, and the first groove 114 is communicated with the first interface 111, the second interface 112 and the third interface 113. The valve core 120 is rotatably arranged in the first groove 114. The valve core 120 is provided with three communicating holes 121 which are respectively opposite to the first interface 111, the second interface 112 and the third interface 113, and the three communicating holes 121 are communicated with each other; a twist handle 122 is fixedly provided on the side surface of the valve core 120, and the twist handle 122 includes three torsion bars 123, and the three torsion bars 123 are respectively parallel to the three communicating holes 121.
