The working principle is as follows:

[0046] When the hanging ring group 10 is in the folded state, see Figure 8 and Fig. 9, due to the action of the elastic member 32, the anti-skid pad 33 of the self-locking device 30 is closely attached to the inner wall 22 of the rod body 20, and the hanging ring group 10 is fixed relative to the rod body 20 in the length direction of the rod body 20. At this time, except for the hanging ring 17 located at the end of the hanging ring group 10, the left end of the first slide 18c of each hanging ring 17 abuts against the left end of the second slide 18d of the hanging ring 17 adjacent to its left, and the right end of the first slide 18c of the hanging ring 17 abuts against the right end of the second slide 18d of the hanging ring 17 on its left. Then the distance between the clothing hanging parts 19 of adjacent hanging rings 17 is the smallest.

[0047] Keep the self-locking device 30 at the left end of the hanging ring group 10 in a locked state, pull the pulling piece 31 at the right end downward to make the anti-slip pad 33 leave the inner wall 22 of the rod body 20, then the hanging ring group 10 is unlocked, and continue to pull the pulling piece 31 at the right end to the right along the track 21, then the pulling piece 31 at the right end pulls the hanging ring 17 connected to it to move, until the sliding part 18 of the hanging ring 17 pulls another hanging ring 17 connected to it to move to the right, and multiple hanging rings 17 are pulled open in turn until the distance between the hanging parts 19 of two adjacent hanging rings 17 is the largest, release the pulling piece 31 at the right end, then the hanging ring group 10 is locked to maintain the expanded state.

[0048] In practical applications, one end of the hanging ring group 10 is fixed relative to the rod body 20, and the other end is provided with a pulling end 11, on which a self-locking device 30 is provided, so that only the pulling end 11 with the self-locking device 30 can be locked or unlocked.

[0049] During use, the utility model can effectively meet the demand of evenly moving the hanging holes of the hanging ring group horizontally to the left and right for drying, and after self-locking, it can also prevent the hanging rings from gathering due to wind and affecting the drying effect.

[0050] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
