[0036] Working principle: Rotating the rotating disk 703 drives the rotating rod 701 to rotate, which in turn drives the worm gear 702 to rotate. The worm gear 702 drives the worm wheel 706 to rotate, which in turn drives the rotating shaft 705 to rotate. The rotating shaft 705 drives the upper connecting box 2 to rotate, which in turn drives one of the connecting female heads 8 to rotate. This facilitates adjustment of the angle between the two connecting female heads 8, improving the flexibility of the connection. After adjustment, rotating the fastening bolt 704 tightly locks the rotating disk 703 against one side of the protective box 6. To improve the stability of the rotating disk 703, the shift fork 114 is then moved, causing the sliding rod 112 to move. The sliding rod 112 causes the locking pin 113 to retract and compress the return spring 115. Then, the male connector 12 is inserted into the corresponding female connector 8, and the inner sleeve pin 13 is inserted into the corresponding outer sleeve block 10. Then, the shift fork 114 is moved again, and under the elastic reset of the return spring 115, the locking pin 113 is pushed into the corresponding locking hole, quickly fixing the inner sleeve pin 13 and improving the connection efficiency of the female connector 8 and the male connector 12.
