A male compression spring is provided between the opposite end faces of the male valve core and the male valve core base.

6. The pipe joint according to claim 1, characterized in that, The female connector further includes a female sealing ring, which is sleeved on the outside of the female valve core; and / or, The male connector also includes a male sealing ring, which is sleeved on the outside of the male valve core.

7. The pipe joint according to claim 1, characterized in that, The pipe fitting also includes: A detection device, disposed between the male connector and the female connector, is used to detect whether the male connector and the female connector are plugged in; and, The controller is electrically connected to the detection device and the drive unit, so that when the detection device detects that the male connector and the female connector are plugged in, it controls the drive unit to drive the holding part to the holding position.

8. The pipe joint according to claim 7, characterized in that, The detection device includes one of a magnetic proximity switch, a photoelectric proximity switch, and a mechanical pressure sensor.

9. The pipe fitting according to claim 8, characterized in that, The detection device includes a mechanical pressure sensor, which comprises: A tube body is provided at the female end connector, the tube body having an installation end and a trigger end disposed opposite to each other, the installation end facing the male end connector; A probe, disposed within the tube body, extends from the mounting end and trigger end respectively at its two ends. A contact protrusion is provided on the side of the probe, near the trigger end. The probe is movable along the axial direction of the tube body, allowing it to move such that the contact protrusion separates from the trigger end when the male and female connectors are inserted, and to move such that the contact protrusion contacts the trigger end when the male and female connectors are separated; and, The sensing component, electrically connected to the controller, includes a sensing part and a trigger part disposed on the surface opposite to the contact protrusion and the trigger end, respectively.
