Under the action of the traveling wheel 14, it can prevent the telescopic plate 12 from tilting due to being unable to bear the weight of the trash can 3, thus causing the trash can 3 to fall over.

[0035] Preferably, a railing 14 is provided at the tail of the sweeper 1. One end of the railing 14 is hinged to the sweeper 1, and the railing 14 is selectively rotated horizontally around its hinged part with the sweeper 1 to abut against one end of the telescopic plate 12 away from the head of the sweeper 1, or to abut against one side of the trash can 3 away from the head of the sweeper 1; the other end of the railing 14 is selectively detachably connected to the sweeper 1; when the sweeper 1 is traveling normally or when there is no need to replace the trash can 3, under the action of the railing 15, it can prevent the telescopic plate 12 from extending or the trash can 3 from detaching from the sweeper 1.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
