1. A joint comprising:
a male module comprising:
a core rod comprising:
a first outer periphery; and
a piston head; and
a sliding cylinder slidably sleeved on the first outer periphery and comprising:
a first valve port that is disposed on an interior surface of the sliding cylinder and is hermetically fit with the piston head; and
a first end comprising a first docking port; and
a first tightening spring coupled to the core rod and the sliding cylinder; and
a female module configured to dock with the male module and comprising:
a valve body comprising:
a first channel disposed in the valve body;
a second valve port disposed in the first channel; and
a second docking port configured to communicate with the first channel; and
a piston slidably disposed in the first channel and further hermetically fit with the second valve port,
wherein after hermetically docking the first docking port and the second docking port:
the core rod is configured to slide in a first direction extending from the first docking port; and
the piston head is configured to:
separate from the first valve port;
slide in a first direction of retracting into the second docking port when the core rod is sliding; and
separate from the second valve port, wherein the first tightening spring is configured to drive the core rod to slide in a second direction of retracting into the first docking port to enable the piston head to hermetically contact with the first valve port.
