In other embodiments, the locking portion 41 is slotted for installation and removal of the fastener 90.

In one embodiment, the connection portion 91 is threadedly mounted in the locking hole 23, and the tightening direction of the fastener 90 is the same as the tightening direction of the first locking member 40.

Specifically, the tightening direction of the fastener 90 is the same as the tightening direction of the locking member, and in the installation process, the first locking member 40 is preferentially connected with the first connecting column 20, and then the fastening member 90 is screwed with the first connecting column 20. During tightening of the fastener 90, the first connecting post 20 has a tendency to move upward, and because the first connecting post 20 is in threaded connection with the first locking member 40, the locking member has a tendency to move downward relative to the first connecting post 20, i.e., the locking effect of the locking member is better.

The utility model also provides a cleaning robot, which comprises the dust pushing device 100, wherein the dust pushing device 100 is arranged on the robot body.

It will be appreciated that the dust pushing device of the present embodiment may be applied to other devices or structures according to actual needs, or the dust pushing device of the present embodiment may be used alone. Moreover, the cleaning robot of the present embodiment also has the above advantages, and will not be described herein.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; the technical features of the above embodiments or in the different embodiments may also be combined within the idea of the utility model, the steps may be implemented in any order, and there are many other variations of the different aspects of the utility model as described above, which are not provided in detail for the sake of brevity; while the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
