The surface of the fixing nut 18 is provided with a slot 9 for use with the positioning block 8.

[0034] During operation, the overall length of the hanging rod 1 can be adjusted by setting an adjustment component. The insertion plug 4 is installed in the wall, and the interior of the insertion plug 4 is a threaded type used in conjunction with the hanging rod 1, so that the hanging rod 1 can be retracted into the interior of the insertion plug 4. After the hanging rod 1 is retracted, the length exposed at the bottom of the mounting plate 3 can be adjusted in length and extension, and the length can be adjusted without cutting. The hanging rod 1 is moved up and down by rotating it, and the hanging rod 1 can be stored in the insertion plug 4 to reduce the degree of shrinkage. At the same time, the anti-loosening component is clamped on the surface of the fixing nut 18. The hanging rod 1 is at a vertical downward angle, so a fixing nut 18 is provided in the mounting plate 3 to position the hanging rod 1 as a whole. The recessed block 7 is pushed by the pull rod 6 to drive the positioning block 8 to be clamped into the card slot 9 to form a positioning to prevent the fixing nut 18 from loosening under shaking conditions. After the fixed thread is positioned, the position of the hanging rod 1 will not be displaced, thereby increasing stability.

[0035] Furthermore, a groove 10 is provided on one side of the mounting plate 3, and a movable plate 11 is threadedly fixed to the surface of the pull rod 6, and the surface of the movable plate 11 fits in contact with the inner wall of the groove 10;

[0044] During operation, by cooperating with the rubber block 16 and the rubber groove 17 , the clamping block 15 drives the rubber block 16 to clamp into the rubber groove 17 , forming a clamping connection, further increasing positioning and preventing separation.

[0045] Working principle: The user rotates the hanging rod 1, and the thread on the surface of the hanging rod 1 moves up and down in the mounting plate 3. The insertion plug 4 is installed in the wall, and the interior of the insertion plug 4 is a threaded type used in conjunction with the hanging rod 1, so that the hanging rod 1 can be retracted into the interior of the insertion plug 4. After the hanging rod 1 is retracted, the length exposed at the bottom of the mounting plate 3 can be adjusted in length and extension, and no cutting is required, reducing the cutting process. At the same time, the fixed nut 18 is limited to prevent the hanging rod 1 from moving up and down, and the block 15 is pulled. The block 15 drives the pull rod 6 and the recessed block 7 to move, thereby driving the positioning block 8 to move. When the pull rod 6 moves, it drives the movable plate 11 to move, and the movable plate 11 drives the spring 12 to deform under force. The movable plate 11 drives the slider 14 to move in the slide groove 13. When there is no force, the spring 12 will reset and drive the positioning block 8 into the slot 9 on the surface of the fixing nut 18 to prevent it from detaching.
