[0017] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the following will further illustrate the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0018] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0019] An embodiment is as follows Figures 1 to 5 As shown, a fastening device for a desk lamp includes a desk lamp body 2 and a study desk body 1 that facilitates the installation and establishment of the desk lamp body 2. The desk lamp body 2 is vertically arranged on the study desk body 1 through the fastening device. The desk lamp body 2 includes a lamp tube 21 and a lamp head 22 provided at the end of the lamp tube 21. Regarding the establishment of the desk lamp body 2 and the study desk body 1, they are all existing mature and commonly used technical means, and will not be elaborated specifically; in order to ensure that while the desk lamp body 2 is adjusted up and down, convenient fastening can be completed, the fastening device includes two parts: a lamp tube 21 fastening device and a lamp tube 21 end fastening device. The lamp tube 21 fastening device is sleeved in the middle of the lamp tube 21 and is connected to the back of the bookshelf of the study desk body 1 through screws. The lamp tube 21 end fastening device is sleeved at the bottom end of the lamp tube 21 and is connected to the bottom of the study desk board of the study desk body 1 through screws. The above establishment mainly ensures the stability of the fastening device and provides convenient conditions for the up and down adjustment of the desk lamp body 2 inside it, fully improving the use functionality of the device and equipment. The fastening process is simple and convenient to operate, and the practicality is significantly improved.

[0020] In the above process: by changing the structure and position of the existing desk lamp, and using the cooperation between the established lamp tube 21 fastening device and the lamp tube 21 end fastening device, it can be stably fastened at any height above the study desk while still being able to adjust the height up and down, and at the same time, the illumination area can be adjusted and increased, thereby expanding its use range; the design of this device is reasonable, the structure is simple, the processing is convenient, and it can effectively and quickly adjust the height of the desk lamp, enabling the desk lamp to meet different use ranges, ensuring the use effect, and effectively meeting the use requirements.

[0021] In order to achieve the up and down adjustment of the lamp tube 21 while completing the action of fastening height, the lamp tube 21 fastening device includes a D-shaped block 3. A first through hole 31 consistent with the cross-section of the lamp tube 21 is provided at the center of the D-shaped block 3 to facilitate the up and down adjustment of the lamp tube 21. A screw hole D132 perpendicular to the first through hole 31 is provided in the middle of the straight side of the D-shaped block 3, and its purpose is to be locked to the back of the bookshelf through screws. A screw hole D233 is provided in the middle of the arc side of the D-shaped block 3 for locking when the lamp tube 21 is adjusted up and down.

[0022] To prevent the table lamp from sliding down after being lifted or lowered vertically, the end fastening device of the lamp tube 21 includes a U-shaped block 4. A second through hole 41 consistent with the cross-section of the lamp tube 21 is provided at a position on the U-shaped block 4 that is away from the straight edge and close to the arc edge. At least two screw holes U142 are provided on one side of the straight edge of the U-shaped block 4, and a screw hole U243 is provided on the outer side of the arc edge of the U-shaped block 4. Under the above design, the screw hole U243 and the screw hole D233 form a 90-degree angle with each other. Therefore, the locking force of the two screws also reaches a stable effect.

[0023] To effectively improve the aesthetics of the device and equipment, the locking screws used for locking or loosening, which are arranged in the screw hole D233 of the D-shaped block 3 and the screw hole U243 of the U-shaped block 4, can be headless screws 5, which fully enhances the aesthetics during the installation of the equipment components. When the user is satisfied with the height of the table lamp, the headless screw 5 is tightened to fix the lamp tube 21. When vertical lifting or lowering is required, it is loosened to achieve vertical lifting or lowering, and the free adjustment of different usage heights is completed to meet the usage requirements.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention in any other form. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as the technical solution content of the present invention is not departed from, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
