Joint assembly and faucet

A joint assembly, comprising:

• a first joint;
• and
• a second joint;
• wherein the first joint defines a first channel penetrating through the first joint in a length direction thereof, and the first joint comprises a first coupling portion, a first connecting structure, and a first guide structure;
• wherein the first connecting structure and the first guide structure are disposed on the first coupling portion, the first guide structure comprises at least two guide pieces, the at least two guide pieces are disposed around the first joint in the length direction of the first joint, and the at least two guide pieces are spaced apart from each other and are disposed on an outer wall of the first coupling portion;
• wherein each of the guide pieces comprises two first guide walls, and the two first guide walls of each of the guide pieces intersect at one end of each of the guide pieces to form a first guide tip of each of the guide pieces;
• wherein the second joint comprises a second channel penetrating through the second joint in a length direction thereof, and the second joint comprises a second coupling portion, a second connecting structure, and a second guide structure, wherein the second connecting structure and the second guide structure are disposed on the second coupling portion;
• wherein the second guide structure comprises at least two guide plates, the at least two guide plates are disposed around the second joint in the length direction of the second joint, the at least two guide plates are spaced apart from each other and are disposed on an inner wall of the second coupling portion, a guide groove is defined between each two adjacent guide plates of the at least two guide plates, and each guide groove is corresponding to a corresponding one of the at least two guide pieces;
• wherein each of the guide plates comprises two second guide walls, and two second guide walls of each of the guide plates intersect at one end of each of the guide plates to form a second guide tip of each of the guide plates;
• wherein the first guide structure and the second guide structure guide the first coupling portion and the second coupling portion to rotate relative to each other in a sleeving process, so as to limit the movement direction of the first coupling portion and the movement direction of the second coupling portion, so that the first connecting structure is aligned with the second connecting structure;
• wherein when the second coupling portion is sleeved on the first coupling portion, each of the guide pieces is accommodated in a corresponding guide groove and is slidable in the corresponding guide groove, each first guide tip faces the second coupling portion, each second guide tip faces the first coupling portion, and the two first guide walls of each of the guide pieces are disposed in the corresponding guide groove and are slidable relative to at least one of two adjacent guide plates;
• wherein when the second coupling portion is sleeved on the first coupling portion, the first connecting structure is connected to the second connecting structure to fix a position of the first coupling portion relative to the second coupling portion.
