1. A joint structure, coupling an input tube with an output tube, the joint structure comprising:
a joint plug assembly for communicating with the input tube, comprising:
a plug body defining a receiving channel along a longitudinal direction for communicating with the input tube, the receiving channel comprising a first receiving hole and a second receiving hole communicating with the first receiving hole, a latching portion being formed at a distal end of the plug body,a sealing member received in the first receiving hole, anda flexible member received in the first receiving hole, an end of the flexible member resisting the input tube, and an opposite end of the flexible member resisting the sealing member to make the sealing member to be partly received in the second receiving hole; and a joint outlet assembly for communicating with the output tube, and comprising:
an outlet body for coupling with the output tube, the outlet body defining a latching groove to receive the latching portion, anda pin received in the latching groove, and defining at least one groove along a longitudinal direction, the at least groove communicating with the output tube, wherein the second receiving hole is located at a side of the first receiving hole adjacent to the outlet body, the pin is capable of being inserted into the second receiving hole to push the sealing member, thereby enabling the input tube to communicate with the at least one groove and the output tube. |
