And during the rotation of the female connector 103, the guiding plate 303 will rotate inside the guiding slot 309, so as to support the position of the female connector 103 and enable it to rotate stably. After that, hold the insertion block 301 and move it to the surfaces of the male connector 102 and the female connector 103. After the insertion block 301 is in place, the surface of the connecting block 205 will be inserted into the inside of the connecting slot 2,04. Hold the movable plate 208 and rotate it. Drive the positioning plate 206 to rotate during the rotation of the movable plate 208.
