As shown in fig. 3, further, each of the upper slider unit and the lower slider unit includes a collar 4, a thimble 5 and a thimble spring 6, the collar 4 is sleeved outside the suspension rod 1 and is not in contact with the suspension rod 1, that is, the inner diameter of the collar 4 is larger than the outer diameter of the suspension rod 1; an extension sleeve 7 connected with the lantern ring 4 is arranged on the inner side of the damping spring 2, the thimble spring 6 is placed in the inner cavity of the extension sleeve 7, one end of the thimble 5 is abutted to the thimble spring 6, and the other end of the thimble penetrates through the lantern ring 4 and then is abutted to the suspender 1. It should be noted that the distance between the bottom of the inner cavity of the extension sleeve 7 and the suspension rod 1 is smaller than the sum of the length of the thimble 5 and the length of the thimble spring 6 when the thimble is naturally not stressed, so that the thimble 5 can be always abutted against the suspension rod 1 under the pushing action of the thimble spring 6 after being mounted, and good contact can be kept.
Further, in order to facilitate smooth movement of the upper slider unit and the lower slider unit, the end of the thimble 5 contacting the suspension rod 1 is a conical structure, and the end is a sharp point.
Further, the interval between the upper slider unit and the lower slider unit is one pitch distance or a plurality of pitch distances when the damping spring 2 is in a natural state.

The suspension rod assembly of the invention has a damping spring part, wherein a metal rod, namely an extension sleeve, extends from two ends of a fixed certain screw pitch respectively, and a metal thimble extends from the extension sleeve and is contacted with the suspension rod to form a loop. A device for measuring the resistance is arranged on the suspension rod. When the damping spring part of the suspender component is subjected to different forces, the length of the damping spring can be changed, a metal loop formed by the extending sleeve, the thimble and the suspender, which extend out of the damping spring part, can be changed, and the device for measuring the resistance judges the change of the load in the washing tub by measuring the resistance change of the metal loop, so that the weighing function of the washing machine is realized.
The principle that the hanger rod assembly realizes the weighing function detection is that the size of the load in the washing barrel is judged by measuring the change of the resistance value between the two thimbles. The working principle diagram is shown in figure 6.
