Side plates 12 are symmetrically fixedly connected to both sides of the housing 1. Two sets of first cleaning roller brushes 14 are symmetrically installed on the surface of the side plates 12. A second cleaning roller brush 15 is rotatably connected to the surface of the side plates 12 at the middle position of the two sets of first cleaning roller brushes 14. A limit slot 151 is opened at the center of the outer wall of one side of both the second cleaning roller brush 15 and the first cleaning roller brush 14. A fixing component 2 is installed inside the limit slot 151.

[0035] The fixing component 2 includes a tube 21 that is inserted into the limiting slot 151 at one end. Limiting rods 211 are symmetrically fixedly connected to the outer walls of both sides of the tube 21. A cavity is opened inside the tube 21.

[0036] By first removing the protective cover 13, then pulling out the T-block 26 and the slide plate 23, the inclined groove 231 simultaneously drives the two sets of locking rods 24 to retract inward. At this time, the spring 25 is compressed to prepare for the reset of the slide plate 23 and the two sets of locking rods 24. Then, the insert 21 is pulled out from the spline sleeve 121 installed on the surface of the side plate 12 and from the first cleaning roller and the second cleaning roller, thereby realizing the quick disassembly and assembly of the first cleaning roller brush 14 and the second cleaning roller brush 15, effectively improving the disassembly and assembly efficiency.

[0044] The working principle of this utility model is as follows: First, the protective cover 13 is disassembled, then the T block 26 and the slide plate 23 are pulled out. The inclined groove 231 simultaneously drives the two sets of locking rods 24 to retract inward. At this time, the spring 25 is compressed to prepare for the reset of the slide plate 23 and the two sets of locking rods 24. Then, the insert 21 is pulled out from the spline sleeve 121 installed on the surface of the side plate 12 and from the first cleaning roller and the second cleaning roller, thereby realizing the quick disassembly and assembly of the first cleaning roller brush 14 and the second cleaning roller brush 15, effectively improving the disassembly and assembly efficiency.
