[0065] Furthermore, in some embodiments, at least one notch 10242 is provided on the end surface of the clamping portion 10241 , which facilitates the assembly and disassembly of the second tensioning member 102 and the first tensioning member 101 .

[0066] The air outlet 400 expansion structure further includes an expansion component, which includes but is not limited to a clamping component, a tray component, and a hanging component. The expansion component is connected to the second end of the tensioning structure 100.

[0067] In some embodiments, please combine Figure 3 , Figure 4 As shown, in order to facilitate the replacement of the expansion component, the expansion structure further includes an adapter structure 300, and the adapter structure 300 is connected to the second end of the tensioning structure 100. The adapter structure 300 is provided with a first adapter interface, and the expansion component is provided with a second adapter interface that cooperates with the first adapter interface. In some embodiments, the first adapter interface is a T-shaped adapter slot 301 provided on the adapter structure 300, and the second adapter interface is a T-shaped adapter (not shown in the figure), and the T-shaped adapter can be plugged into the T-shaped adapter slot 301.

[0068] In some embodiments, see Fig.11As shown, the first tensioning surface 1012 of the first tensioning member 101 is provided with a first rubber pad 1016. The first rubber pad 1016 can improve the fit and anti-slip effect between the first tensioning surface 1012 and the first side 401 of the air outlet 400. In some embodiments, the second tensioning surface 1021 of the second tensioning member 102 is provided with a groove 201, and a relatively soft second rubber pad 104 is provided in the groove 201. The second rubber pad 104 can improve the fit and anti-slip effect between the second tensioning surface 1021 and the second side 402 of the air outlet 400.

[0069] In some embodiments, see Figure 3 and Figure 4 As shown, a connection structure 200 is further provided between the transition structure 300 and the tensioning structure 100, and the first end of the connection structure 200 is connected to the second end of the tensioning structure 100, and the second end is connected to the transition structure 300.

The grooves 201 can improve the bending strength of the connection plate.

[0070] In some embodiments, see Fig.11 and Fig.12 As shown, the above-mentioned transition structure 300 is provided with a buckle part 302, and the side of the buckle part 302 facing the tensioning part 1011 of the first tensioning member 101 forms an angle with the connection structure 200, so that the tensioning part 1011, the connection structure 200, the first tensioning member 101 and its tensioning part 1011 form a buckle structure, which can be buckled on the top of the first side 401 of the air outlet 400, and the buckle part 302 is clamped on the side of the first side 401 of the air outlet 400. Fig.13 As shown, before the fastening, external force is applied to both ends of the connection structure 200 to bend it. After it abuts against the first side 401 of the air outlet 400, the external force is removed, and the connection structure 200 returns to its original state, completing the fastening.

[0071] The tensioning mechanism is installed at the air outlet 400, which will affect the air volume at the air outlet 400. Therefore, please refer to Fig.14 As shown, the bottom of the tensioning portion 1011 of the first tensioning member 101 is provided with a first edge 1017, and the bottom of the tensioning portion 1011 and / or the first edge 1017 are provided with a first opening 1026, which can reduce the influence of the first tensioning member 101 on the air volume of the air outlet 400.

[0072] In addition, in some embodiments, see Fig.15 As shown, in order to match some air outlets 400 with an inclined angle, the second edge 1022 of the second tensioning member 102 has a horizontal angle, so that the second edge 1022 of the second tensioning member 102 is more consistent with the bottom slope of the second side 402 of the air outlet 400.

[0073] Example 2, please refer to Fig.16 As shown, one of the differences between this embodiment and embodiment 1 is that the tensioning portion 1011 includes a first tensioning portion 10111 and a second tensioning portion, and the second tensioning member 102 is disposed between the first tensioning portion 10111 and the second tensioning portion at the first end of the first tensioning member 101. The second tensioning member 102 can be selectively opened to the inside or outside of the first tensioning member 101.

[0074] like Fig.16 As shown, when the tensioning structure 100 is in the air outlet 400 and the second tensioning member 102 is tensioned toward the inner side of the first tensioning member 101 , the first tensioning portion 10111 abuts against the second side 402 of the air outlet 400 . The second tensioning member 102 abuts against the first side 401 of the air outlet 400 .

[0075] In order to improve the stability of the tensioning structure 100 , a first edge 1017 is provided at one end of the tensioning portion 1011 extending into the air outlet 400 . When the first tensioning portion 10111 abuts against the second side 402 of the air outlet 400 , the first edge 1017 can be clamped on the bottom of the second side 402 .

[0076] In this embodiment, the second tensioning member 102 can also be opened in the tensioning direction of embodiment 1. Therefore, the first rubber pad 1016 can be arranged on both sides or any one side of the tensioning portion 1011 , and the second rubber pad 104 can be arranged on both sides of the second tensioning member 102 or on one side corresponding to the first rubber pad 1016 .

[0077] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
