[0024] Embodiment 2

[0025] On the basis of Embodiment 1, as Figure 1 and Figure 4As shown, one side of each of the two clamping sleeves 14 is respectively connected to one end of the two auxiliary rods 13 by bearings. The positions of the two clamping sleeves 14 are corresponding. One side of each of the two second arc-shaped plates 9 is respectively fixedly connected to both sides of the second auxiliary sleeve 8. The tops of the two sector plates 11 are respectively fixedly connected to the bottom of the second auxiliary sleeve 8. For the structure of a vacuum cleaner floor brush that is convenient for disassembly, replacement, and installation of the present utility model, by providing the second auxiliary sleeve 8, the limit nut 10, the sector plate 11, and the embedding hole 15, the diameter of the first auxiliary sleeve 5 is the same as that of the second auxiliary sleeve 8. After the extension tube 3 is snap-fitted with the suction tube 2, the two first arc-shaped plates 6 can be flush with the two second arc-shaped plates 9.

[0026] Working principle: The vacuum cleaner floor brush is a part of the vacuum cleaner and is mainly used for cleaning the floor. Usually, bristles 4 are provided on the brush head of the floor brush. The main function of the bristles 4 is to help the vacuum cleaner clean the floor more effectively, especially the dust and dirt on the carpet. The suction port is the part where the floor brush is connected to the vacuum cleaner main body. It conveys the inhaled air and dust to the inside of the vacuum cleaner through the suction tube 2. The floor brush is connected to the vacuum cleaner main body by a threaded connection. The vacuum cleaner main body is equipped with an extension tube 3. The suction tube 2 and the extension tube 3 are often installed by means of a threaded sleeve. Frequent installation and disassembly of the two may cause wear of the threads and reduce the connection stability. If the threads are not aligned, it may cause the two to be not firmly installed, affecting the cleaning effect. Therefore, it is particularly important to design a structure of a vacuum cleaner floor brush that is convenient for disassembly, replacement, and installation. The operator inserts the extension tube 3 into the inside of the suction tube 2. The bottom of the first auxiliary sleeve 5 gradually approaches the top of the second auxiliary sleeve 8. One end of each of the two screw rods 7 is sequentially inserted into the corresponding embedding hole 15. By threading the limit nut 10 with one end of the screw rod 7, the first arc-shaped plate 6 and the second arc-shaped plate 9 can be limited and fixed. By rotating the two limit nuts 10 in the reverse direction, the suction tube 2 and the extension tube 3 can be disassembled from each other, facilitating subsequent disassembly, replacement, and installation of the two. Continuing to rotate the two auxiliary rods 13, one side of each of the two clamping sleeves 14 is respectively connected to one end of the two auxiliary rods 13 by bearings. One side of the clamping sleeve 14 gradually approaches the outer surface of the suction tube 2. The two clamping sleeves 14 can clamp both sides of the suction tube 2, enhancing the stability of the suction tube 2. The diameter of the first auxiliary sleeve 5 is the same as that of the second auxiliary sleeve 8. After the extension tube 3 is snap-fitted with the suction tube 2, the two first arc-shaped plates 6 can be flush with the two second arc-shaped plates 9, facilitating the insertion of the screw rod 7 into the embedding hole 15. The sector plate 11 is located at the bottom of the second auxiliary sleeve 8. By rotating the two auxiliary rods 13 and the clamping of the suction tube 2 by the clamping sleeve 14, the firmness between the second auxiliary sleeve 8 and the suction tube 2 is further enhanced.
