After the installation shaft 130 enters the tubular blind groove 300, the mating surface of the installation shaft 130 and the tubular blind groove 300 can form an axial fixed pair that restricts the axial movement of the installation shaft 130 and restricts the installation The shaft 130 is a circumferential fixed pair that rotates in a circumferential direction, and the circumferential fixed pair is used to lock the axial fixed pair.

The wire winding hook installation assembly 10 is used for accommodating cables of household appliances. The winding hook main body 110 is used for winding the cable, and can also provide support for tightening the cable. The installation plate 200 is used to fix the winding hook 100 and also to limit the cable from falling off. The installation shaft 130 is used to detachably fix the winding hook 100 to the installation plate 200 . The tubular blind groove 300 is used to receive and fix the installation shaft 130 . The shape of the installation shaft 130 corresponds to the shape of the tubular blind groove 300 . The installation shaft 130 can be inserted into the tubular blind groove 300 and can withstand certain pressure and tension. It can be understood that the structure of the installation shaft 130 and the tubular blind groove 300 can be easily installed and disassembled without using any tools. When using the wire-winding hook installation assembly 10, two wire-winding hooks 100 usually need to cooperate. The two winding hooks 100 are installed on the same installation plate 200, and the installation positions have a certain distance. Winding the cable between the two winding hooks 100 can increase the winding amount of the cable.

The winding hook body 110 is provided with a structure for winding the cable and a structure for preventing the cable from falling off.
