When replacing the entire disc brush, as the fastener is gradually loosened, the spring is reset and the elastic force is applied to the inner connecting ring and the outer connecting ring, thereby facilitating the disassembly of the fastener and further improving the overall disassembly efficiency.

[0041] The beneficial effects of this application are:

[0042] 1. The drive mechanism and the disc brush are connected by setting a connecting mechanism. The setting of the connecting mechanism can facilitate the rapid installation and disassembly between the disc brush and the drive mechanism, so as to facilitate the rapid replacement of the disc brush. The symmetrical setting of the two drive mechanisms and the disc brush can further improve the cleaning efficiency of the road sweeper, ensuring that the vehicle can evenly and efficiently clean up the garbage and debris on both sides of the road during the cleaning process;

[0043] 2. The inner diameters of the second through hole and the first through hole are larger than the diameter of the rod, which can prevent the thread of the rod from directly contacting the first through hole and the second through hole. Therefore, during installation or disassembly, only the block will be worn, and the block is a detachable part, which is easy to replace. The connecting rod and the support plate will not be worn, thereby avoiding thread wear caused by multiple disassembly, so that there is no need to replace it even if it is not damaged.

[0044] 3. By setting the inner ring, the outer ring and the spring, when installing the disc brush, as the fastener is gradually tightened, the distance between the inner ring and the outer ring is gradually shortened, and at the same time the spring is squeezed. The spring is in a compressed state and generates a rebound force, and the rebound force acts on the inner ring and the outer ring, thereby improving the locking effect of the fastener. When replacing the entire disc brush, as the fastener is gradually loosened, the spring resets and exerts elastic force on the inner ring and the outer ring, thereby facilitating the disassembly of the fastener, thereby improving the overall disassembly efficiency.
