[0021] The elastic positioning assembly 8 includes a movable ring 9, and the movable ring 9 is movably installed on the outside of the first connector 1. The movable ring 9 is located on the side of the connecting ring 3 away from the annular seat 5. Four positioning columns 10 are evenly fixedly installed on the side of the movable ring 9 close to the connecting ring 3. Four through holes 11 are evenly penetrated inside the connecting ring 3, and the four through holes 11 are horizontally aligned with the four positioning holes 7 respectively. The four positioning columns 10 are respectively movable through the four through holes 11 and extend to the inside of the four positioning holes 7. A positioning ring 12 is provided on the side of the movable ring 9 away from the connecting ring 3, and the positioning ring 12 is fixedly installed on the outside of the first connector 1.
