[0030] In the embodiments of the present disclosure, as Figures 3-6As shown, when the water outlet head 5 is rotated to the rightmost side and the last side, only one group of water inlet holes 6 and one group of water outlet holes 7 will connect the water inlet head 1, the cavity inside the inner cylinder 3 and the water outlet head 5. After the rotation adjustment of the water outlet head 5 and the adjusting cylinder 4, one of the water inlet holes 6 on the adjusting cylinder 4 will be aligned with the only one water inlet hole 6 on the inner cylinder 3. Therefore, the water in the water inlet head 1 can flow into the cavity inside the inner cylinder 3, and at the same time, the only one water outlet hole 7 on the adjusting cylinder 4 will be aligned with one of the water outlet holes 7 on the inner cylinder 3, so that the water inside the inner cylinder 3 flows outwards through the water outlet head 5.

[0031] In the embodiments of the present disclosure, as shown in Figures 3-6 As shown, the adjusting shell 2, the inner cylinder 3 and the adjusting cylinder 4 are all cylindrical shells, the adjusting cylinder 4 is located in the annular cavity between the inner cylinder 3 and the adjusting shell 2, and the outer wall of the adjusting cylinder 4 is in close contact with the inner side of the adjusting shell 2 and the outer side of the inner cylinder 3, so that the adjusting cylinder 4 can be stably rotated and avoid shaking.

[0032] In the embodiments of the present disclosure, as shown in Figures 1-3 As shown, the top right side of the adjusting cylinder 4 is provided with a threaded hole corresponding to the positioning screw 8, and the top right side and the top rear side of the adjusting shell 2 are both provided with a circular hole penetrating up and down. When the water outlet head 5 is rotated and adjusted, the threaded hole at the top of the adjusting cylinder 4 will be aligned with the circular hole at the top right side or the top rear side of the adjusting shell 2 up and down, and then the positioning screw 8 can be inserted into the threaded hole at the top of the adjusting cylinder 4 through the circular hole at the top of the adjusting shell 2, so as to lock the positions of the adjusting cylinder 4 and the water outlet head 5.

[0033] In the embodiments of the present disclosure, as shown in Figure 2 and Figure 4 As shown, an opening is arranged on the outer wall of the adjusting shell 2, and the water outlet head 5 can be rotated by 90° in the opening on the outer wall of the adjusting shell 2, so that the structure can be adjusted to a direct head or an L-shaped joint, which is more adaptable.

[0034] In the embodiments of the present disclosure, as shown in Figures 3-6 As shown, the water inlet holes 6 and the water outlet holes 7 are arranged staggered up and down, and the water inlet holes 6 on the inner cylinder 3 are located on the right side of the water inlet head 1, and the water outlet holes 7 on the adjusting cylinder 4 are located on one side of the water outlet head 5. After the rotation adjustment of the water outlet head 5 and the adjusting cylinder 4, one of the water inlet holes 6 on the adjusting cylinder 4 will be aligned with the only one water inlet hole 6 on the inner cylinder 3. Therefore, the water in the water inlet head 1 can flow into the cavity inside the inner cylinder 3, and at the same time, the only one water outlet hole 7 on the adjusting cylinder 4 will be aligned with one of the water outlet holes 7 on the inner cylinder 3, so that the water inside the inner cylinder 3 flows outwards through the water outlet head 5. The staggered arrangement of the water inlet holes 6 and the water outlet holes 7 up and down also avoids the coincidence of the two, so as to avoid the water leakage.

[0035] In the embodiments of the present disclosure, as shown in Figures 1-6As shown, the edges of the water inlet hole 6 and the water outlet hole 7 on the inner cylinder 3 and the adjusting cylinder 4 can be covered with a layer of rubber, so that when the adjusting cylinder 4 is rotated for adjustment, the rubber on the edges of the water inlet hole 6 and the water outlet hole 7 on the inner cylinder 3 and the adjusting cylinder 4 will always be in close contact with the gap of the contact surface of the outer wall, thereby ensuring the sealing and avoiding the situation of water seepage outward.

[0036] The working principle of the embodiment is as follows: when the structure needs to be used to assemble and connect plastic pipes, if a direct head is needed to connect the pipes, the water outlet head 5 can be rotated to the rightmost side under the support of the adjusting shell 2, at this time the adjusting cylinder 4 will also rotate inside the adjusting shell 2, and the threaded hole at the top of the adjusting cylinder 4 will be aligned with the circular hole at the right top of the adjusting shell 2, then the positioning screw 8 can be inserted through the circular hole at the right top of the adjusting shell 2 and screwed into the threaded hole at the top of the adjusting cylinder 4, thereby locking the positions of the adjusting cylinder 4 and the water outlet head 5, so that the structure can be used as a direct head; if an L-shaped joint is needed to connect the pipes, the water outlet head 5 can be rotated to the leftmost side under the support of the adjusting shell 2, at this time the adjusting cylinder 4 will also rotate inside the adjusting shell 2, and the threaded hole at the top of the adjusting cylinder 4 will be aligned with the circular hole at the back top of the adjusting shell 2, then the positioning screw 8 can be inserted through the circular hole at the back top of the adjusting shell 2 and screwed into the threaded hole at the top of the adjusting cylinder 4, thereby locking the positions of the adjusting cylinder 4 and the water outlet head 5, so that the structure can be used as an L-shaped joint; and after the rotation adjustment of the water outlet head 5 and the adjusting cylinder 4, one of the water inlet holes 6 on the adjusting cylinder 4 will be aligned with the only one water inlet hole 6 on the inner cylinder 3, so that the water in the water inlet head 1 can flow into the cavity inside the inner cylinder 3, and the only one water outlet hole 7 on the adjusting cylinder 4 will be aligned with one of the water outlet holes 7 on the inner cylinder 3, so that the water inside the inner cylinder 3 can flow outward through the water outlet head 5, and finally the water inlet head 1 and the water outlet head 5 can be fused with the water inlet end and the water outlet end pipes, respectively.
