[0072] The female head inner sleeve 12 moves in a direction away from the female end head 16 , the female head 1 and the male head 2 are connected, the automatic docking process is completed, and the fluid flows into the male head 2 .

[0073] The automatic unlocking process specifically includes the following steps:

[0074] The motor 31 drives the conveyor belt 320 to rotate counterclockwise or clockwise, so that the movable block 327 on the conveyor belt 320 contacts the telescopic rod transmission block 324, and the telescopic rod transmission block 324 pushes the male head 2 to move toward the female head 1 through the sliding sleeve telescopic rod 325 and the sliding sleeve.

[0075] When the truncated cone shell 212 contacts the locking claw 1121 in the female head 1 , the male head 2 continues to move toward the female head 1 , and at the same time, the locking claw 1121 is squeezed by the truncated cone shell 212 and retracts into the arc-shaped shell 112 .

[0076] When the locking claw 1121 retracts to contact the edge of the inner sleeve claw 221, both the male inner sleeve 22 and the female inner sleeve 12 fall back toward the base 29, and the fluid is cut off.

[0077] The sliding sleeve continues to move toward the female head 1, and when the locking claw 1121 in the female head 1 is completely squeezed and retracted to contact the edge of the male head shell 21, the male head shell 21 falls back toward the base 29, and the female head 1 is disengaged from the male head 2, completing the automatic unlocking process.

[0078] The pipeline quick connector provided by the utility model is provided with a motor 31 and a driving assembly 32, and the driving assembly 32 drives the male head 2 to dock or unlock with the female head 1.
