Fig. 4 is a schematic view of the leaf scanning mechanism shown in fig. 2 at another view angle, fig. 5 is a schematic view of a section A-A in the leaf scanning mechanism shown in fig. 4, and fig. 6 is an exploded schematic view of a leaf scanning roller in the leaf scanning mechanism shown in fig. 3. As shown in fig. 4-6, in some embodiments, one of the plugging shaft 112 and the mounting shaft 111 is configured with a mating hole 1111, and the other is mated within the mating hole 1111. Specifically, the insertion hole 1111 is formed on the mounting shaft 111, that is, the end of the mounting shaft 111 has a larger size than the end of the plugging shaft 112 facing the mounting shaft 111, so that the plugging shaft 112 can be sleeved on the inner wall of the mounting shaft 111. Through the plug-in cooperation of the plug shaft 112 and the mounting shaft 111, the limit of the plug shaft 112 on the leaf sweeping assembly can be realized, and the connection effect of the leaf sweeping assembly and the mounting shaft 111 is ensured.

By arranging the plurality of groups of the leaf sweeping brushes 130, the sweeping area of the leaf sweeping brushes 130 is increased, and the sweeping efficiency is improved. Meanwhile, as the plurality of groups of the leaf sweeping brushes 130 are in a split type design, compared with the mode of installing one leaf sweeping brush 130 with a larger size, the leaf sweeping brushes 130 can be replaced in a targeted mode, the whole leaf sweeping brush group does not need to be replaced, and maintenance cost is reduced.

Wherein, the blades 131 of the adjacent blade-sweeping brushes 130 are arranged at an angle along the axial direction of the mounting shaft 111. That is, adjacent blades 131 are offset from each other in the axial direction of the mounting shaft 111. Thus, when one group of the blade-sweeping brushes 130 rotates to be parallel to the ground, the blades 131 of the other group of the blade-sweeping brushes 130 can contact with the ground, so that the probability of the blade-sweeping brushes 130 contacting with the ground is increased, real-time blade-sweeping is realized, and the cleaning efficiency is improved.

In a specific embodiment, as shown in fig. 2 and 3, the leaf scanning mechanism 100 further includes a handle 140, where the handle 140 is sleeved on an end of the mounting shaft 111 away from the plugging shaft 112.
