[0007] As a further setting of the above scheme, a second connecting ring is connected to the outer side of the upper end of the support tube, and two elongated holes are provided on one side of the second connecting ring. A second connecting shaft is slidably connected between the two elongated holes to facilitate adjustment of the position of the second connecting shaft in the elongated hole, laying the foundation for adjusting the spacing between the limit plate and the support tube, and the outer side of the second connecting shaft is rotatably connected to the limit plate, and a plurality of first protrusions are provided on the side of the limit plate close to the support tube, and the first protrusions are engaged with the second card slots, so that the first protrusions and the second card slots can be separated before adjusting the spacing between the top end of the support tube and the base, and the spacing between the LED light board and the base, thereby releasing the restriction of the first protrusion on the position of the support tube. After the height of the support tube is adjusted to a suitable position, the first protrusion is inserted into the second card slot to fix the position of the support tube.

[0008] As a further arrangement of the above scheme, second protrusions are provided at both ends of the lower side of the protective cover, which are engaged with the first card slot to protect the threaded rod, keep the threaded rod tidy, and reduce the workload of cleaning the threaded rod.

The threaded rods can also be rotated at the same time to adjust the distance between the support blocks and the base, thereby adjusting the distance between the base and the storage surface, and then adjusting the overall height of the LED desk lamp.

[0011] The use of the bolt can loosen the nut in the bolt before adjusting the inclination angle between the sleeve and the base, releasing the fixation of the bolt and the mounting seat to the first connecting seat so as to rotate the first connecting seat. The combination of the mounting plate and multiple baffles can adjust the inclination angle between the sleeve and the base to a suitable position. By abutting the end of the connecting plate away from the support tube against the baffle, the connecting line between the connecting rod, sleeve and mounting plate forms a shape approximately similar to a triangle, thereby keeping the sleeve stable, and tightening the nut to restore the fixation of the bolt and the mounting seat to the first connecting seat, and further fix the sleeve.

[0012] When the sleeve and the connecting rod are in a vertical state, the combination of the baffle and the connecting rod can also be used as a mobile phone or tablet holder, thereby improving the practicality of the LED desk lamp. The combination of the limit plate and the first protrusion can fix the support tube before and after the distance between the LED light board and the base is adjusted, so that the support tube and the LED light board remain stable to meet the user's personalized needs. The design of the storage slot in the protective cover is convenient for placing objects such as pens, rulers and remote controls, which is convenient for users to access, further improving the practicality of the LED desk lamp.

[0025] like Figure 1 、 Figure 2 and Figure 6When the locking plate 33 is unlocked, the locking plate 33 is unlocked and the locking plate 33 is unlocked, so that the user can lock the locking plate 33. When the user locks the locking plate 33, the user can lock the locking plate 33.

[0026] like Figure 1 and Figure 7 As shown, second protrusions 51 are provided at both ends of the lower side of the protective cover 5, and the second protrusions 51 are engaged with the first card slot 11, which can protect the threaded rod 13, keep the threaded rod 13 clean, and reduce the workload of cleaning the threaded rod 13. A storage slot 52 is provided in the middle of the protective cover 5, which is convenient for placing objects such as pens, rulers and remote controls, making them convenient for users to use.

[0027] The easily adjustable LED desk lamp disclosed in this embodiment has the following steps: before use, remove the protective covers 5 from both sides of the base 1; when the desktop of the LED desk lamp is uneven, place the base 1 on the uneven desktop, observe the tilt direction of the base 1, rotate the threaded rod 13 in the tilt direction to adjust the distance between the support block 14 and the base 1, so that the anti-slip pad 141 under the support block 14 fits with the desktop, and squeeze the desktop to straighten the base 1 so that the upper plane of the base 1 remains horizontal; then restore the connection between the second protrusion 51 and the first slot 11, and cover the two protective covers 5 on the threaded rods 13 on both sides respectively; turn on the power of the controller 15, and then use the controller 15 to control the switch of the LED light board 4; during use, the threaded rod 13 can also be rotated in turn to adjust the distance between the base 1 and the desktop to meet the user's personalized needs.

[0028] When adjusting the distance between the LED light board 4 and the base 1 when the sleeve 2 is vertical, it is only necessary to pull the limit plate 33 toward the end of the elongated hole 311 away from the support tube 3, so that the second connecting shaft 32 slides in the elongated hole 311. After the first protrusion 34 is separated from the second slot 241, hold the limit plate 33, and you can use the second connecting ring 31 to adjust the connection depth between the support tube 3 and the sleeve 2 upward or downward, so as to adjust the vertical distance between the LED light board 4 and the base 1 to a suitable position. Then, press the limit plate 33 toward one side of the support tube 3, adjust the position of the second connecting shaft 32 in the elongated hole 311, and make the first protrusion 34 gradually approach the first slot 11 until the connection between the first protrusion 34 and the first slot 11 is restored. Then, use the controller 15 to turn on or off the LED light board 4. During the lighting process of the LED light board 4, the side of the tablet or mobile phone can be placed between two adjacent baffles 171, so that the other side of the tablet or mobile phone rests on the connecting rod 23. At this time, the connecting rod 23, the connecting line between two adjacent points between the mounting plate 17 and the tablet or mobile phone is approximately a triangle, which can keep the tablet or mobile phone stable and free the user's hands.

[0029] When it is necessary to adjust the inclination angle between the sleeve 2 and the base 1, loosen the nut in the bolt 161, hold the sleeve 2 by hand, and bend the sleeve 2 and the connecting rod 23 toward one side of the limit plate 33, so that the first connecting seat 21 at the lower end of the sleeve 2 is rotated a certain angle around the bolt 161. When the lower end of the connecting rod 23 is completely separated from the baffle 171, pull the connecting rod 23 by hand to turn the inclination direction of the sleeve 2 to one side of the connecting rod 23, and make the end of the connecting rod 23 away from the sleeve 2 rest against the baffle 171 in the appropriate position, tighten the nut, and restore the fixing of the mounting seat 16 to the first connecting seat 21 and the sleeve 2. The inclination angle between the sleeve 2 and the base 1 is inversely proportional to the distance between the baffle 171 and the mounting seat 16, that is, the farther the connecting rod 23 rests against the baffle 171 from the mounting seat 16, the smaller the inclination angle between the sleeve 2 and the base 1. After the adjustment and fixing are completed, it can be used.

[0030] In the conveniently adjustable LED desk lamp disclosed by the present invention, the base 1, sleeve 2, support tube 3, LED lamp board 4, protective cover 5, threaded rod 13, anti-slip pad 141, controller 15, bolt 161, baffle 171, connecting rod 23, first connecting ring 24, second slot 241, second connecting ring 31, long hole 311, second connecting shaft 32, limit plate 33, first protrusion 34, second protrusion 51 and storage slot 52 and other components are all universal standard parts or components known to those skilled in the art, and their structure and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
