[0031] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0032] Example 1:

[0033] Cooperate Figures 1 to 3 As shown in Embodiment 1 of this utility model, an adjusting switch device A is disclosed, which is applied to a telescopic rod. The adjusting switch device A specifically includes a housing 1, an adjusting switch component 2, and an elastic reset component 3. The housing 1 is integrally injection molded and has an operating hole 11 communicating with its inner cavity. The adjusting switch component 2 is rotatably fitted into the housing 1 and is also integrally injection molded. The adjusting switch component 2 has an integrally formed pressing part 21 and a pull rope linkage part 22. The pressing part 21 is movably accommodated in the operating hole 11, and the pull rope linkage part 22 is used to connect the pull rope of the telescopic rod and is linked to the pin of the telescopic rod's limiting device via the pull rope. The elastic reset component 3 is accommodated in the housing 1, positioned between the housing 1 and the adjusting switch component 2, and is used to drive the adjusting switch component 2 to reset. The adjusting switch component 2 integrates the swing arm and button of existing switching devices, thus simplifying the structure and giving the adjusting switch device A of this utility model the advantages of simple structure and convenient assembly.

[0034] In the first embodiment of this utility model, the housing 1 has a mounting port 12 that communicates with the inner cavity of the housing 1. The mounting port 12 is opposite to the operating hole 11, so that the adjusting switch 2 and the elastic reset member 3 can be easily installed through the mounting port 12.

[0035] In the first embodiment of this utility model, elastic buckles 16 are provided on both sides of the housing 1, so that the adjustment switch device A of this utility model can be installed in the inner tube of the telescopic rod by means of buckle connection, which is simple to install.

[0036] In the first embodiment of this utility model, the adjusting switch 2 is rotatably connected to the housing 1 via the connecting rod 4. The adjusting switch 2 is provided with a rotating hole 23 for rotatably fitting the connecting rod 4, and the housing 1 is provided with an insertion hole 13 for inserting and engaging with the connecting rod 4.

The elastic reset member 3 is a compression spring, and its two ends abut against the housing 1 and the pressing part 21 of the regulating switch member 2, respectively. When the pressing part 21 of the regulating switch member 2 is pressed, the elastic reset member 3 is compressed by the pressing part 21. When the pressing part 21 of the regulating switch member 2 is released, the elastic reset member 3 extends and resets, thereby driving the regulating switch member 2 to reset.

[0039] In the first embodiment of this utility model, the housing 1 is provided with a limiting post 14 that is inserted and cooperates with the elastic reset member 3, and the pressing part 21 of the adjusting switch member 2 is provided with a positioning post 24 that is inserted and cooperates with the elastic reset member 3; the limiting post 14 and the positioning post 24 can prevent the elastic reset member 3 from shifting by limiting and positioning the elastic reset member 3.

[0040] Example 2:

[0041] Cooperate Figure 4 and Figure 5 As shown, the difference between Embodiment 2 and Embodiment 1 of this utility model lies in the different arrangement of the elastic reset member 3. Specifically, in Embodiment 2 of this utility model, the elastic reset member 3 is located between the housing 1 and the pull cord linkage 22 of the adjusting switch member 2. The elastic reset member 3 is a compression spring, and its two ends abut against the housing 1 and the pull cord linkage 22 of the adjusting switch member 2, respectively. When the pressing part 21 of the adjusting switch member 2 is pressed, the elastic reset member 3 is compressed by the pull cord linkage 22. When the pressing part 21 of the adjusting switch member 2 is released, the elastic reset member 3 extends and resets, thereby driving the adjusting switch member 2 to reset.

[0042] In the second embodiment of this utility model, the housing 1 is provided with a limiting post 14 that is inserted and cooperates with the elastic reset member 3, and the pull rope linkage part 22 of the adjusting switch member 2 is provided with a positioning post 24 that is inserted and cooperates with the elastic reset member 3; the limiting post 14 and the positioning post 24 can prevent the elastic reset member 3 from shifting by limiting and positioning the elastic reset member 3.

[0043] Example 3:

[0044] Cooperate Figure 6 and Figure 7As shown, the difference between Embodiment 3 and Embodiment 1 of this utility model lies in the different arrangement of the elastic reset member 3. Specifically, in Embodiment 3 of this utility model, the elastic reset member 3 is located between the housing 1 and the pressing part 21 of the adjusting switch 2. The elastic reset member 3 is a tension spring, and its two ends are respectively connected to the pull rope linkage part 22 of the housing 1 and the adjusting switch 2. When the pressing part 21 of the adjusting switch 2 is pressed, the elastic reset member 3 is stretched; when the pressing part 21 of the adjusting switch 2 is released, the elastic reset member 3 retracts and resets, thereby driving the adjusting switch 2 to reset.

[0045] In the third embodiment of this utility model, the housing 1 is provided with a hook part 15 connected to one end of the elastic reset member 3, and the adjusting switch member 2 is provided with a hook part 25 connected to the other end of the elastic reset member 3.
