Through a series of structural arrangements, the utility model can adjust and fix the inclination angle, orientation angle and height position of the bedside lighting lamp head 102 according to usage needs, so that it can be adapted to different usage needs, improve usage flexibility, and facilitate personnel to use.

[0027] Working principle: when in use, the base 100, the support tube 1, the extension rod 2, the mounting block 4, the circular shaft 6, the rotating disk 5 and the supporting cross bar 101 cooperate to support the bedside lighting lamp head 102. During use, when the inclination angle of the bedside lighting lamp head 102 needs to be adjusted, the supporting cross bar 101 can be directly rotated, and the supporting cross bar 101 drives the bedside lighting lamp head 102 to rotate, and the supporting cross bar 101 drives the rotating disk 5 to rotate, and the rotating disk 5 drives the circular shaft 6 to rotate. When the rotating disk 5 rotates, it also drives the two fifth friction elastic rubber sleeves 7 to rotate frictionally between the two sixth friction elastic rubber sleeves 8. When the bedside lighting lamp head 102 is adjusted to the required inclination angle, the supporting cross bar 101 can be stopped from rotating. When the rotation stops, the rotating disk 5 is locked under the friction force between the fifth friction elastic rubber sleeve 7 and the corresponding sixth friction elastic rubber sleeve 8, so that the supporting cross bar 101 and the bedside lighting lamp head 102 are fixed, and no self-rotation occurs under the friction force and when there is no external force to rotate;

[0028] When a person sits under the bedside lighting lamp 102 to read a book and needs to adjust the height of the bedside lighting lamp 102, the rocker 11 can be directly rotated, and the rocker 11 drives the second bevel gear 10 to rotate, and the second bevel gear 10 drives the first bevel gear 9 meshing with it to rotate, and the first bevel gear 9 drives the screw 3 to rotate. Under the action of the threaded hole on the extension rod 2, the screw 3 rotates and drives the extension rod 2 to move upward. The extension rod 2 drives the supporting cross bar 101 to move upward through the mounting block 4, the circular shaft 6 and the rotating disk 5 in turn, and the supporting cross bar 101 drives the bedside lighting lamp 102 to move upward, so that the height of the bedside lighting lamp 102 changes. After the adjustment is appropriate, stop rotating the rocker 11, and under the action of the threaded hole and the screw 3's own thread locking force, the bedside lighting lamp 102 is fixed;

[0029] When the direction angle of the bedside lighting lamp head 102 is adjusted according to the use needs, the handle rod is directly rotated to drive the rotating ring 12 to rotate, and the rotating ring 12 drives the support tube 1 to rotate. When the rotating ring 12 rotates, it also drives the third friction elastic rubber sleeve 15 to rotate frictionally on the top of the fourth friction elastic rubber sleeve 16. When the support tube 1 rotates, it also drives the rotating shaft 14 to rotate. The rotating shaft 14 drives the second friction elastic rubber sleeve 18 to rotate frictionally in the first friction elastic rubber sleeve 17. The support tube 1 drives the support cross bar 101 to rotate through the extension rod 2, the mounting block 4, the round shaft 6 and the rotating disk 5 in turn, and the support cross bar 101 drives the bedside lighting lamp head 102 to rotate so that its direction angle When the degree changes and the required orientation angle is adjusted according to the needs of use, stop rotating the handle rod, and under the friction force between the third friction elastic rubber sleeve 15 and the fourth friction elastic rubber sleeve 16, and the friction force between the second friction elastic rubber sleeve 18 and the first friction elastic rubber sleeve 17, the support tube 1 is fixed, thereby fixing the bedside lighting lamp head 102. This method of adjusting the orientation angle does not require personnel to rotate the base 100 as a whole, which is convenient for personnel to operate. In addition, the adjustable orientation angle and height position of the bedside lighting lamp head 102 can be suitable for different usage needs, improve usage flexibility, and facilitate personnel to use.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
