[0026] A blocking block 4 is disposed between the small nozzle 1 and the side plate 32 . The blocking block 4 is mounted on the small nozzle 1 and abuts against the inner wall of the wing portion 32A of the end plate 33 .

[0027] The wiper nozzle and clip interlocking structure disclosed in the present invention has a block 4 clamped between the nozzle 1 and the side plate 32, and the block 4 abuts against the inner wall of the wing 32A of the end plate 33, so that the wing 32A is limited in the area surrounded by the end plate 33 and the bottom plate 31 by the block 4, so that when the clip 3 is subjected to the pulling force and has a tendency to deform inward, the block 4 supports it in the reverse direction, thereby preventing the wing 32A from deforming and shifting toward the middle of the clip and detaching from the hook plate 2, and the wing 32A will not shift toward the middle of the clip 3 and detach from the hook plate 2, thereby ensuring the firmness and reliability of the hook plate 2 fixing the clip 3, and further ensuring the reliability of the clip 3 fixing the nozzle 1, thereby improving the anti-detachment property of the nozzle 1.

[0028] In order to further improve the anti-dropping property of the small nozzle 1 , preferably, the clip 3 further includes an end plate 33 located at the left end of the bottom plate 31 ; a hook 5 is provided at the right end of the blocking block 4 , and the hook 5 is hung with the end plate 33 .

[0029] By hooking the hook 5 set at the right end of the blocking block 4 with the end plate 33, under the action of the pulling force, the hook 5 and the end plate 33 are buckled together, locking the relative position of the blocking block 4 and the clip 3 along the pulling direction, and the blocking block 4 is installed on the small nozzle 1, thereby improving the reliability of the cooperation between the small nozzle 1 and the clip 3, and avoiding the small nozzle 1 and the clip 3 from detaching from each other.

[0030] The hook 5 can be arranged in the middle of the right end of the block 4. In the embodiment disclosed in the present invention, a notch II 6 is arranged between the end plate 33 and the corresponding side plate 32; the hook 5 is arranged in the notch II 6. In this structure, the hook 5 is arranged in the notch II 6, so that the block 4 covers the wing 32A along the length direction of the clip 3, increases the contact area between the block 4 and the wing 32A, and improves the reliability of the block 4 limiting the wing 32A.

[0031] The hook portion of the hook 5 can extend toward the bottom plate 31. In the embodiment disclosed in the present invention, the hook portion of the hook 5 extends toward the middle of the clip 3. With this structure, under the pressure of the wing 32A, the reliability of the hook 5 and the end plate 33 is improved, and the manufacturing of the block 4 and the hook 5 is simpler.

[0032] Preferably, Figure 4 As shown, the block 4 located on the outside of the small nozzle 1 and the corresponding hook 5 form an L-shaped structure, and the right side surface of the outer block 4 is arranged opposite to the end plate 33 of the clip 3; the hook 5 abuts against the wing 32A, so that the hook 5 also limits the wing 32A, further improving the ability to prevent the wing 32A from deviating toward the middle of the clip 3.

[0033] like Figure 5 As shown, the blocking block 4 located inside the small nozzle 1 and the corresponding hook 5 form a linear structure.
