Based on the embodiment, a corresponding push-pull movable connection structure can be arranged at the contact end of the shovel bar support and the top surface of the fixing piece, for example, a slide rail is arranged on the shovel bar support close to the top surface of the fixing piece, a slide rail is correspondingly started on the top surface of the fixing part, and the shovel bar support and the top surface of the fixing piece are in push-pull movable connection through the slide rail and the slide rail.

Based on the embodiment, the corresponding contact end surfaces of the shovel bar body and the pressing plate are provided with a limiting notch and a limiting step, and the limiting step and the limiting notch in the embodiment can be the structures described in the first embodiment and the second embodiment.

In this scheme shovel strip structure is fixed in on the cleaning appliance through the installation space activity that forms between clamp plate and the mounting of locking, because shovel strip structure often contacts with ground friction, be the wearing and tearing part, or when dragging and sweeping the in-process carelessly touch hard object, because shovel strip structure is soft material, can damage or tear, in time change in order to be convenient for the consumer when damaging, design shovel strip structure for can follow installation space pull roll-off formula structure, simultaneously offer one and supply shovel strip conveniently to take out the opening of taking out at the cleaning appliance side, during the change, only need with shovel strip follow side opening roll-off direct change can, the problem that the cleaning appliance apron need be changed entirely or the consumer can't independently be changed and need return to the factory maintenance at present is avoided, also prolonged the length of the rubbish passageway that whole shovel strip corresponds the cleaning roller to form simultaneously, more be favorable to thin granule rubbish to accumulating into medium granule rubbish in long and thin granule rubbish in the rubbish passageway, more be favorable to getting rid of thin granule rubbish from the cleaning roller.

The above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: it may be modified or equivalent substitutions and combinations of partial structures (technical features) of the foregoing embodiments may be made in the foregoing embodiments, and these modifications or substitutions and combinations do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model, unless the embodiments explicitly exclude the possibility of substituting or combining structures (technical features) of different embodiments, or such substitution or combination is contrary to the overall concept of the utility model.
