[0024] Working principle: by placing the bottle body 12 between the clamping blocks 903, the clamping arm 902 of the outer wall of the hook 1101 is stretched by the tension spring 1102, so as to achieve the effect of driving the clamping block 903 to fix the bottle body 12, and then by tightening the fastening nut 1002, it is easy to prevent the clamping arm 902 from loosening, and by rotating the rotating handle 7, the connecting plate 6 drives the screw rod 3 to rotate, so as to achieve the effect of driving the stabilizing plate 1 to move and rise and fall, and through the movement of the stabilizing plate 1, it is easy to adjust the height of the bottle body 12 according to the use requirements.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
