[0039] In some other embodiments of the utility model, referring to Figures 3 to 5One of the two adjacent second rod segments 1021 is provided with a clamping block 1023, and the other is provided with a clamping slot 1024. Relative rotation of the two adjacent second rod segments 1021 can drive the clamping block 1023 and the clamping slot 1024 to rotate relative to each other and approach each other until they are clamped. In this embodiment, the relative rotation and clamping of the clamping block 1023 and the clamping slot 1024 are used to achieve the rotational connection between the second rod segments 1021.
[0040] In a more specific embodiment of the above embodiment, the clamping block 1023 is a resilient clamping block. Relative rotation of the two adjacent second rod segments 1021 can drive the resilient clamping block and the clamping slot 1024 to rotate relative to each other and approach each other. When they are relatively close, the resilient clamping block is pushed into the clamping slot 1024, thereby clamping with the clamping slot 1024.
[0041] In another more specific embodiment of the above embodiment, as shown in Figure 4 and Figure 5 , the other of the two adjacent second rod segments 1021 is further provided with a resilient clamp 25, and the clamping slot 1024 is arranged in the clamping gap of the resilient clamp 25. When the two adjacent second rod segments 1021 rotate relative to each other, the resilient clamp 25 opens to allow the clamping block 1023 to enter the clamping gap and be clamped into the clamping slot 1024.
[0042] The opening of the resilient clamp 25 can be driven by the clamping block 1023. As shown in Figure 4 , the resilient clamp 25 is provided with a supporting surface 26. Relative rotation of the two adjacent second rod segments 1021 can drive the clamping block 1023 to abut against the supporting surface 26 and move towards the clamping slot 1024 to open the resilient clamp 25.
[0043] The opening of the resilient clamp 25 can also be driven by other components. For example, a driving part (not shown in the figure) can be provided on the first rod segment 1011. When the two adjacent first rod segments 1011 rotate relative to each other, the driving part rotates and opens the resilient clamp 25.
[0044] The supporting surface 26 includes a plurality of inclined surfaces inclined relative to the moving direction of the clamping block 1023. From the position away from the clamping slot 1024 to the position close to the clamping slot 1024, the distance between the plurality of inclined surfaces gradually decreases. Thus, as the clamping block 1023 moves towards the clamping slot 1024, the clamping block 1023 first abuts against the position with a large distance between the plurality of inclined surfaces, and then gradually abuts against the position with a small distance between the plurality of inclined surfaces, thereby opening the resilient clamp 25.
[0045] The supporting surface 26 can also include one inclined surface and one flat surface, or can be a non-inclined surface such as an arc surface, as long as the distance between the positions close to the clamping slot 1024 is smaller than the distance between the positions away from the clamping slot 1024.
[0046] In order to facilitate disassembly of two adjacent second rod segments 1021, in some embodiments of the utility model, the elastic clamp 25 is opened when two adjacent second rod segments 1021 relatively reverse rotate, so that the clamping block 1023 is detached from the clamping slot 1024.
[0047] The elastic clamp 25 in the above embodiment includes a plurality of clamping arms 251, Figure 4 And Figure 5 The example in the middle is two, which can also be three, four, etc., a plurality of clamping arms 251 are arranged along the circumference of the second rod segment 1021, the elastic clamp 25 is opened, that is, a plurality of clamping arms 251 are dispersed, and after the clamping block 1023 enters the clamping gap and is clamped into the clamping slot 1024, a plurality of clamping arms 251 of the elastic clamp 25 are gathered.
[0048] In order to facilitate the clamping block 1023 to rotate and be clamped with the clamping slot 1024, the clamping block 1023 is a circular truncated cone in the embodiment, and is coaxially arranged with the corresponding second rod segment 1021, the shape of the clamping position of the clamping block 1023 around the circular truncated cone is the same, so that the clamping effect with the clamping slot 1024 is the same no matter the rotation angle, thereby avoiding the occurrence of unstable clamping.
[0049] In order to relatively rotate the two adjacent first rod segments 1011 to drive the two adjacent second rod segments 1021 to relatively rotate, referring to Figure 6 In the embodiment, the first rod segment 1011 and the second rod segment 1021 inside it are limited by the limiting ribs A and the limiting grooves B / limiting ribs A (that is, the limiting ribs A and the limiting grooves B cooperate, and the limiting ribs A cooperate with the limiting ribs A), so as to prevent the first rod segment 1011 and the second rod segment 1021 from relatively rotating in the circumferential direction of the brush rod 100, thereby, when an assembler holds two first rod segments 1011 to relatively rotate, two second rod segments 1021 inside the two first rod segments 1011 can also be driven to relatively rotate.
[0050] The utility model embodiment further provides a cleaning brush, including brush rod 100 and brush head 200, the brush rod 100 is any one embodiment of the brush rod 100 described above. The cleaning brush in the embodiment can be a toilet brush, a floor brush, a window brush and the like, or various cleaning wipers, such as a mirror wiper for wiping a mirror, a table top wiper and the like.

[0052] In addition, the relative rotation of the two first rod sections 1011 in the embodiment changes the total length of the two first rod sections 1011, and / or the relative rotation of the two second rod sections 1021 changes the total length of the two second rod sections 1021, so that the length of the entire outer rod 101 is adjusted by the connection between the two first rod sections 1011, or the length of the entire inner rod 102 is adjusted by the connection between the two second rod sections 1021, so that the length of the outer rod 101 / inner rod 102 is more suitable for user use.
