[0012] (1) The utility model enables the user to change the position of the pressure ring by rotating the rotating block on the locking bracket through the cooperation of the strip hole, the locking bracket and the connecting block. At the same time, when the pressure ring presses the rubber sleeve, the friction between the rubber sleeve and the hemispherical cover can prevent the spherical hollow block from rotating in the hemispherical cover. When the pressure ring releases the hemispherical cover, the spherical hollow block can rotate in the hemispherical cover. Furthermore, through the cooperation of the hemispherical cover, the first circular hole, the spherical hollow block, the rubber sleeve, the pressure ring, the strip hole, the locking bracket and the connecting block, the direction of the end can be adjusted according to actual use requirements, thereby making the application range of the special-shaped three-way aluminum joint wider.

[0013] (2) The utility model provides a second circular hole, a second internally threaded tube, a fixing bolt and a fixing groove. When the pressure ring presses the rubber sleeve, the fixing bolt is screwed into the fixing groove to lock the first internally threaded tube, thereby making it difficult for the pressure ring and the rubber sleeve to loosen, thereby making the end of the special-shaped three-way aluminum joint more firmly fixed.

When the pressure ring 8 loosens the rubber sleeve 7, the end head 5 can rotate freely in the first circular hole 4. The surfaces of the vertical tube 1 and the horizontal tube 2 are both provided with strip holes 9. The surfaces of the vertical tube 1 and the horizontal tube 2 are both fixedly connected with locking brackets 10. The inner wall of the locking bracket 10 and the surface of the pressure ring 8 are both fixedly connected with connecting blocks 11. The surface of the connecting block 11 contacts the inner wall of the strip hole 9. The pressure ring 8 cannot rotate through the cooperation of the strip hole 9 and the connecting block 11.

[0029] The locking bracket 10 includes an externally threaded barrel 101, the surface of the vertical tube 1 and the surface of the horizontal tube 2 are in contact with the inner wall of the externally threaded barrel 101, the inner wall of the externally threaded barrel 101 is fixedly connected to the surface of the connecting block 11, the surface of the externally threaded barrel 101 is threadedly connected with a first internally threaded barrel 102, the inner wall of the first internally threaded barrel 102, the surface of the vertical tube 1 and the surface of the horizontal tube 2 are fixedly connected with a bearing 103, the first internally threaded barrel 102 is fixed to the vertical tube 1 and the horizontal tube 2 through the bearing 103, and the first internally threaded barrel 102 can be freely Rotation: Through the cooperation of the strip hole 9 and the connecting block 11, the external threaded tube 101 cannot rotate, and then when the first internal threaded tube 102 rotates, the external threaded tube 101 can be moved on the horizontal tube 2 or the vertical tube 1 through the thread.
