When changing the discharge direction, the user rotates the discharge pipe 55, and the rotation of the discharge pipe 55 drives the sleeve 54 to rotate, and the rotation of the sleeve 54 drives the sealing plate 8 to rotate, and the rotation of the sealing plate 8 drives the rotating block 9 to rotate, and the sealing plate 8 and the rotating block 9 rotate along the track of the groove. When reaching a suitable angle, the contact block 103 limits the position of the discharge pipe 55 when the rotating wheel 104 is rotated, and the rotating wheel 10 4 drives the screw 101 to rotate, and the screw 101 rotates along the meshing trajectory of the fixing block 102. The rotation of the screw 101 drives the contact block 103 to rotate, and the contact block 103 contacts the surface of the tube body 51 to complete the fixation. After the discharge pipe 55 is fixed, the staff rotates the sealing cover 562, and the sealing cover 562 rotates along the trajectory of the thread groove.
