Referring to fig. 3, the nozzle of the nozzle 01 is formed by enclosing a first notch 1 and a second notch 2 which are arranged on a joint, that is, the joint 01 is provided with a plurality of first notches 1 and second notches 2 which are uniformly distributed along the circumferential direction and are arranged at intervals;

the first notch 1 and the second notch 2 are both blind grooves and are provided with an opening end and a closed end; the open end of the first notch 1 has a first inclined surface 11, the open end of the second notch 2 has a second inclined surface 21, and the inclination angle O1 of the first inclined surface 11 is smaller than the inclination angle O2 of the second inclined surface 21 (in the present embodiment, O1 is 20 degrees, and O2 is 40 degrees), and the depth H1 of the first inclined surface 11 is smaller than the depth H2 of the second inclined surface 21.

When the two joints 01 are combined together, different injection ports can be formed between the first notch 1 on one joint 01 and the second notch 2 on the other joint 02 along with the rotation position change of the two joints 01, and the formed injection ports are distributed in a staggered mode, specifically:

as shown in fig. 2 to 6, a convex portion 3 is formed between the first notch 1 and the second notch 2 which are distributed on the same joint 01 at intervals, the convex portion 3 also has a first inclined surface 11 and a second inclined surface 21, respectively, and the convex portion 3 has at least the following positions along with the position change when the two joints 01 are involuted;

as shown in fig. 2, in the first position, the convex portion 3 abuts against the second notch 21, the second inclined surface 21 of the convex portion 3 of one joint 01 abuts against the second inclined surface 21 of the convex portion 3 of the other joint 01, and it can be seen that after the two joints 01 are involuted, two kinds of nozzles K1 and K2 are formed, and adjacent K1 and K2 are dislocated (one above the other);

for the illustration of fig. 6, it can be seen that after two joints 01 are involuted, three kinds of spouts K6, K7, K8 are formed;

in fact, the spouts formed in figures 5 and 6 are structurally identical, with the difference that the position and distribution are totally different, but the three spouts formed in figures 5 and 6 are still mutually offset;

meanwhile, in the present embodiment, it can be seen that the nozzles are all surrounded by the notches, and therefore the structural shape of the nozzles is also determined by the shape of the notches, in the present embodiment, the closed ends of the first notch 1 and the second notch 2 are both flat surfaces, and respectively form a first bottom surface 12 and a second bottom surface 22, and the width of the first bottom surface 12 is the same as the width of the second bottom surface 22; in addition, the closed ends of the first notch 1 and the second notch 2 may have bottom surfaces with other structures, for example, the bottom surface of the first notch 1 may be arc-shaped, and the bottom surface of the second notch 2 may have both flat and arc-shaped forms.

Further, in order to make the injection more uniform, on the basis of the staggered distribution of the nozzles, the depths of the first notch 1 and the second notch 2 can be selected differently, so that the sizes of the nozzles formed by surrounding are different, for example, on the basis of fig. 5, the depth of the first notch 1 can be further reduced, and the second notch 2 can also extend along the direction of the second inclined surface 21, so that the depth of the second notch 2 is increased; it should be noted, however, that since the protrusion 3 is located in the first notch 1, in order to reduce interference with the protrusion 3, the first notch 1 is preferably provided with a transition surface 13, i.e., as shown in fig. 4, the transition surface 13 is selected to be a straight surface.
