Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figure 1-4 A quick and easy assembly / disassembly roller brush device includes a main body 1 and a roller brush disposed on the lower side of the main body 1. A metal outer cover 2 is installed on one side of the main body 1, and a limiting rod 12 is provided on one side of the metal outer cover 2. A limiting hole 13 is provided inside one side of the main body 1 to cooperate with the limiting rod 12, and the limiting rod 12 is disposed inside the limiting hole 13. A five-pointed star bolt 10 and a butterfly bolt 9 are respectively provided on one side of the metal outer cover 2, and one end of the five-pointed star bolt 10 is disposed inside the main body 1, and the butterfly bolt 9 is disposed on one side of one end of the metal outer cover 2. The roller brush is located at the bottom of the main body 1. The metal cover 2 is used to fix the roller brush. The limiting rod 12 on one side of the metal cover 2 cooperates with the limiting hole 13 to pre-limit the position of the metal cover 2, so that it can be fully installed with the main body 1. After removing and installing the metal cover 2, the roller brush can be easily removed from the bottom of the main body 1. The metal cover 2 is installed by a five-pointed star bolt 10 and two corresponding butterfly bolts 9. Both the five-pointed star bolt 10 and the butterfly bolts 9 can be manually rotated and removed. The roller brush includes a soft brush 3 and a hard brush 5. The inside of the main body 1 is provided with a PU rod 16, and the outside of the PU rod 16 is provided with a mounting shaft 14. The soft brush 3 and the hard brush 5 are respectively set on the outside of the mounting shaft 14 at the corresponding positions.

[0022] The metal outer cover 2 has a rotating shaft 4 inside, with one end of the rotating shaft 4 located inside the mounting shaft 14.
