When the volume of the garbage can is required to be reduced, namely the length of the supporting rod is shortened, a certain pressure is manually applied to the upper part or the large cover part of the supporting rod, so that the elastic buckle rebounds to be separated from the clamping groove, the supporting rods of each stage are retracted, the elastic buckle is clamped into the clamping groove and limited after the supporting rods are retracted to a certain position, and the supporting rods are prevented from being pulled out uncontrollably when the garbage can moves, so that the use experience is influenced.

Those skilled in the art will readily understand that the support rod may further adopt other feasible techniques in the prior art to implement multistage mutually nested installation, for example, a spring positioning connection structure is adopted, similar to a telescopic umbrella handle structure of a folding umbrella, the upper end of the outer support rod is provided with a slot, the upper end and the lower end of the inner nested support rod are respectively provided with a compression spring and a limiting block connected with the compression spring, when the inner nested support rod stretches, the limiting block passes through the slot, and the limiting block is embedded into the slot under the action of the compression spring, so as to implement a limiting effect. The telescopic pull rod structure similar to a pull rod box or a telescopic pull rod structure of the children scooter can also be adopted. The telescopic structure of the telescopic clothes hanger in the prior art can also be adopted.

Of course, the support bar 200 may be of a non-telescopic structure, and the large cover 300 may be fixed in position by sliding up and down along the support bar 200. The above technical solution can also achieve the technical effect that the large cover 300 approaches or approaches the ground depending on the support bar 200. For example, a sliding groove is formed in the support bar 200, the large cover 300 is provided with a sliding portion matched with the sliding groove, the sliding portion and the sliding groove are respectively provided with a corresponding through hole, and a screw can pass through the through holes to fix the large cover 300 and the support bar 200. The above-mentioned technology is the prior art and will not be described in detail herein.
