[0043] In some embodiments, the extending direction of the first connecting portion is parallel to the extending direction of the first cleaning sheet 20, and the extending direction of the second connecting portion is parallel to the extending direction of the second cleaning sheet 30. Thus, by controlling the angle between the first connecting portion and the second connecting portion, the angle between the first cleaning sheet 20 and the second cleaning sheet 30 can be controlled.

[0044] It can be understood that the angle between the first cleaning sheet 20 and the second cleaning sheet 30 is determined by the setting positions of the first connecting portion and the second connecting portion. The included angle α between the first cleaning sheet 20 and the second cleaning sheet 30 is between 30° and 220°, so that the bracket assembly 1 can be applicable to different cleaning scenarios to clean the included angle, sharp corner or surface of the object to be cleaned, improving the cleaning efficiency of the object to be cleaned.

[0045] According to some embodiments of the present utility model, the included angle α between the first cleaning sheet 20 and the second cleaning sheet 30 is 180°. It can be understood that through the above setting, it is convenient for the bracket assembly 1 to clean the surface of the object to be cleaned, and the cleaning effect on the surface of the object to be cleaned is good.

[0046] Embodiment Three:

[0047] Based on Embodiment One, in this embodiment, the first cleaning sheet 20 includes a cleaning portion 21 and a third connecting portion connected to each other, the first connecting portion is detachably connected to the third connecting portion, and the second cleaning sheet 30 is integrally formed with the second connecting portion.

[0048] It can be understood that the second cleaning piece 30 is integrally formed with the second connecting part, that is, the second cleaning piece 30 is integrally formed with the cleaning head 10, which facilitates the production and manufacturing of the bracket assembly 1 and improves the production efficiency of the bracket assembly 1.

Thus, through the above arrangement, the user can selectively disassemble and assemble the first cleaning piece 20 according to different scenarios, which is convenient for the user to carry out the cleaning work. At the same time, when the first cleaning piece 20 is worn, only the first cleaning piece 20 can be replaced, avoiding replacing the entire bracket assembly 1 and reducing the use cost of the bracket assembly 1.

[0049] According to some embodiments of the present invention, one of the first connecting part and the third connecting part is configured as a clamping groove 11, and the other of the first connecting part and the third connecting part is configured as a clamping block.

[0050] In some embodiments, the first connecting part is configured as a clamping block. At this time, the cleaning head 10 is provided with a clamping block, and the first cleaning piece 20 is provided with a clamping groove 11. The clamping block is received in the clamping groove 11 to fix the first cleaning piece 20 to the cleaning head 10. In other embodiments, the first connecting part is configured as a clamping groove 11. At this time, the cleaning head 10 is provided with a clamping groove 11, and the first cleaning piece 20 is provided with a clamping block. The clamping block is received in the clamping groove 11 to fix the first cleaning piece 20 to the cleaning head 10, and no limitation is made here.

[0052] In some embodiments, two clamping inserts 221 are provided at one end of the cleaning part 21, and the two clamping inserts 221 are spaced apart from each other, and the two clamping inserts 221 can be selectively deformed towards or away from each other to facilitate the cooperation between the clamping inserts 221 and the clamping groove 11. At the same time, after the clamping inserts 221 are received in the clamping groove 11, the two clamping protrusions 222 respectively abut against the inner wall of the clamping groove 11 under the action of the restoring force, so that the clamping inserts 221 can be stably received in the clamping groove 11, thereby improving the connection stability between the first cleaning piece 20 and the cleaning head 10.

[0053] Preferably, the cleaning head 10 is further provided with clamping holes corresponding to the two clamping protrusions 222 respectively. After the clamping inserts 221 are received in the clamping grooves 11, the two clamping inserts 221 move away from each other under the action of the restoring force, so that the clamping protrusions 222 can be received in the clamping holes, and the clamping holes can limit the degree of freedom of the clamping protrusions 222 in the insertion direction, avoiding the clamping inserts 221 from disengaging from the clamping grooves 11, and further improving the connection stability between the first cleaning sheet 20 and the cleaning head 10. It should be noted that when the first cleaning sheet 20 needs to be disassembled, the user can press the two clamping protrusions 222, so that the two clamping inserts 221 are deformed towards each other, and then the clamping inserts 221 can be disengaged from the clamping grooves 11. Thus, through the above settings, the disassembly and assembly of the first cleaning sheet 20 and the cleaning head 10 can be facilitated, and the use flexibility of the bracket assembly 1 is improved.

[0054] According to some embodiments of the present invention, the first cleaning sheet 20 further includes: a limiting protrusion 25, the limiting protrusion 25 is disposed between the clamping insert 221 and the cleaning portion 21, and the limiting protrusion 25 is adapted to abut against the end of the clamping groove 11. It can be understood that after the clamping insert 221 is received in the clamping groove 11, the limiting protrusion 25 can abut against the end of the clamping groove 11, thereby preventing the first cleaning sheet 20 from continuing to move into the clamping groove 11, so as to ensure the matching effect between the first cleaning sheet 20 and the cleaning head 10.

[0055] Embodiment Four:

[0056] Based on Embodiment Three, a fixing block 12 is provided on the cleaning head 10.
