The first T-shaped positioning strip 18 can be slidably inserted into the first T-shaped positioning groove 19 to complete the installation of the first bristle 31. There is friction between the first T-shaped positioning strip 18 and the first T-shaped positioning groove 19. Without applying excessive external force, it will not fall off.

[0034] like Figure 2As shown, the second mounting component includes a second T-shaped positioning strip 20 fixedly connected to the top of the second bristle 32. The bottom of the mounting box 11 is provided with a second T-shaped positioning groove 21 for inserting the second T-shaped positioning strip 20. The second T-shaped positioning strip 20 is slidably inserted into the second T-shaped positioning groove 21 to complete the installation of the second bristle 32. The cooperation between the second T-shaped positioning strip 20 and the second T-shaped positioning groove 21 is the same as the cooperation between the first T-shaped positioning strip 18 and the first T-shaped positioning groove 19 described above.

[0035] like Figure 3 and Figure 4 As shown, the fastener includes a connecting plate 27, a positioning block 26 connected to the top of the connecting plate 27, and a pressing block 28 connected to the bottom of the connecting plate 27. The mounting base 22 has a movable groove for sliding the connecting plate 27. A spring is connected to the side of the connecting plate 27 away from the positioning block 26 and installed in the movable groove. The mounting base 22 has an upper sliding groove 29 for sliding out of the positioning block 26 and a lower sliding groove 30 for sliding out of the pressing block 28 on one side. The inner wall of the adjusting groove 24 has a plurality of positioning grooves 25 for inserting the positioning block 26. The outer wall of the mounting base 22 slides in conjunction with the inner wall of the adjusting groove 24. The bottom of the adjusting groove 24 communicates with the outside.

[0036] Pressing the pressing block 28 allows it to be stored in the sliding groove 30. The connecting plate 27 can then drive the positioning block 26 to be stored in the upper sliding groove 29. At the same time, the mounting base 22 is aligned with the target position in the adjustment groove 24. The pressing of the pressing block 28 is released, and the block is slid and adjusted appropriately. Under the force of the spring, the positioning block 26 is aligned with the corresponding positioning groove 25, fixing the position of the mounting base 22.

[0037] The working principle of this utility model is as follows: the first brush bristles 31 and the second brush bristles 32 are installed, and the telescopic handle 12 can be held to operate the cleaning tool. After adjusting the telescopic handle 12 to a suitable angle, the rotation position of the rotating block 13 is restricted by the limiting member, and the cleaning tool can be operated to clean the door frame. According to the groove and side position of the door frame, a corresponding number of mounting seats 22 can be installed so that the cleaning brush 23 can be placed on the side of the door frame or in the corresponding groove to carry out the door frame cleaning operation. With the help of water spraying, the cleaning effect can be improved.
