In one embodiment, the device with telescoping rod is a clothes dryer.

When the clothes dryer is required to be used, the support rod is fully stretched, when the support rod is fully stretched, the locking end 601 of the elastic sheet 6 of the next-stage rod assembly in the two-stage adjacent rod assemblies is inserted into the locking hole of the rod body of the previous-stage rod assembly, the support rod has a larger length, and the support rod is stretched or contracted along the axial direction due to the fact that the locking end 601 is matched with the locking hole along the radial direction of the rod body, even if the end part of the support rod is subjected to larger bearing force, the support rod cannot be contracted, and the bearing strength of the support rod can be ensured. When the clothes dryer is not needed to be used and stored, the supporting rod is required to retract, the locking end 601 of the elastic sheet 6 of the last level lever assembly is pressed outside the rod body of the last level lever assembly, the rod body of the last level lever assembly is retracted into the rod body of the last level lever assembly after the supporting piece of the last level lever assembly is contacted with the supporting piece of the last level lever assembly, the plug-in unit 502 on the supporting piece of the last level lever assembly is continuously pressed with force to enable the elastic sheet 6 of the last level lever assembly to be inserted into a gap between the elastic sheet 6 of the last level lever assembly and the supporting piece, the elastic sheet 6 of the last level lever assembly is separated from the locking hole of the rod body of the last level lever assembly, the locking between the last level lever assembly and the rod body of the last level lever assembly is released, the rod body of the last level lever assembly can be retracted into the rod body of the last level lever assembly, and compared with the related technology, the whole supporting rod can be completely retracted according to the process, and the user can conveniently store the elastic sheet 6 of the last level lever assembly.

When the telescopic rod is completely retracted and the clothes dryer needs to be used again, the telescopic rod is required to be stretched out, the rod body of the last-stage rod assembly is pulled outwards, when the elastic piece 6 of the last-stage rod assembly moves to the position that the locking end 601 of the elastic piece is opposite to the locking hole on the rod body of the last-stage rod assembly, the locking end 601 of the elastic piece 6 of the last-stage rod assembly is outwards popped out and inserted into the locking hole on the rod body of the last-stage rod assembly, the last-stage rod assembly and the last-stage rod assembly are locked together, then the last-stage rod assembly drives the last-stage rod assembly to outwards continue stretching, and when the elastic piece 6 of the last-stage rod assembly moves to the position that the locking end 601 of the elastic piece 6 of the last-stage rod assembly is opposite to the locking hole on the rod body of the last-stage rod assembly, the last-stage rod assembly outwards pops out and is inserted into the locking hole on the rod body of the last-stage rod assembly, and the last-stage rod assembly is locked together, and the last-stage rod assembly drives the last-stage rod assembly to outwards continue stretching, so that the telescopic rod is completely stretched out.

Although embodiments of the present utility model have been described in connection with the accompanying drawings, various modifications and variations may be made by those skilled in the art without departing from the spirit and scope of the utility model, and such modifications and variations fall within the scope of the utility model as defined by the appended claims.
