With the above structure, when installing the front connecting block 340 and the rear connecting block 350, the front cover 312 and the rear cover 322 may not be installed first, and the front connecting block 340 and the rear connecting block 350 may be inserted into the front first slot 311 and the rear first slot 321 through the front insertion port and the rear insertion port, and then the corresponding end covers are installed.

[0038] In the embodiment, two pairs of conductive tracks 210 are provided, wherein the conductive tracks 210 of one pair are provided at the two groove walls of the front second slot 220 for fixing the lamp body 200, and the conductive tracks 210 of the other pair are provided at the two groove walls of the rear second slot 230 for fixing the lamp body 200, a pair of electrical contacts of the front connecting block 340 are provided and respectively slideably cooperate with the conductive tracks 210 at the two groove walls of the front second slot 220, and a pair of electrical contacts of the rear connecting block 350 are provided and respectively slideably cooperate with the conductive tracks 210 at the two groove walls of the rear second slot 230.

[0039] In the embodiment, a light source is also provided in the fixed lamp body 200, so that it emits light together with the telescopic lamp body 300, and has a strong lighting capability. In the embodiment, the light source can be a light belt or a light bar, or other light-emitting devices.

[0040] In the embodiment, the lower end surface of the fixed lamp body 200 is the light-emitting side, forming a linear light source, and the lower end surfaces of the front side 310, the rear side 320 and the connecting part 330 of the telescopic lamp body 300 are the light-emitting sides, forming a U-shaped light source, and the two U-shaped light sources of the two telescopic lamp bodies 300 are respectively on both sides of the linear light source of the fixed lamp body 200. When the two telescopic lamp bodies 300 are retracted relative to the fixed lamp body 200, the linear light source and the two U-shaped light sources can be combined to form a wider linear light source than the original linear light source, and the lighting is sufficient; when the two telescopic lamp bodies 300 are extended left and right relative to the fixed lamp body 200, the two U-shaped light sources move to the left and right directions, and the range of lighting can be extended to meet the needs of the lighting range. Consumers can adjust the above two states as needed, and the use scenarios are rich. Of course, it is conceivable that the light source settings on the fixed lamp body 200 and the telescopic lamp body 300 are not limited to the above structure, and those skilled in the art can reasonably configure the light sources on the fixed lamp body 200 and the telescopic lamp body 300 as needed.

With the above structure, the two telescopic lamp bodies 300 can cooperate with the front center positioning column 240 and the rear center positioning column 250 after being retracted to achieve positioning and ensure the symmetry of the structure; the adapting recess is used to enclose the adapting hole to cooperate with the center positioning column, so that the telescopic lamp body 300 can maintain a tight structure after being retracted, and the structure is stable, and the appearance is regular. In the embodiment, the front center positioning column 240 and the rear center positioning column 250 are cylinders, and the front adapting recess 313 and the rear adapting recess 323 are semicircular default grooves. It is conceivable that the front center positioning column 240 and the rear center positioning column 250 are not limited to using cylinders, for example, they can also be square cylinders, elliptical cylinders, etc., and the shapes of the front adapting recess 313 and the rear adapting recess 323 can be adapted accordingly.

With the above structure, after the telescopic lamp body 300 is retracted, the left and right ends of the fixed lamp body 200 and the connection parts 330 can be limited by the cooperation of the adapter heads 260 and the adapter recesses 331, and a tighter cooperation is formed at the same time, so that the shape of the lamp body after the telescopic lamp body 300 is retracted is regular and the structure is stable. In addition, with the structure of the front center positioning column 240 and the rear center positioning column 250, after the telescopic lamp body 300 is retracted, both the left and right ends are matched with the fixed lamp body 200, and the structure is tight and stable. In the embodiment, the adapter head 260 is semicircular arc-shaped, and the adapter recess 331 is a semicircular arc groove, so that it can be adapted. Of course, it is conceivable that the adapter head 260 is not limited to a semicircular arc shape, for example, it can also be a square, oval or other shape, and the adapter recess 331 can be set corresponding to the shape of the adapter head 260.

The connecting strip 120 connects the top fixing seat 110 and the fixed lamp body 200. The connecting strip 120 is connected to the upper end surface of the fixed lamp body 200, so that the telescopic lamp has a structure of a chandelier. It is conceivable that in other embodiments, the support assembly 100 may also adopt other structures, such as a lamp stand, and the lamp stand may be provided with a base, so that the telescopic lamp forms a structure of a seat lamp, or the lamp stand is used to be fixed to a wall, so that the telescopic lamp forms a structure of a wall lamp. In the embodiment, the connecting strip 120 is connected to the upper end surface of the fixed lamp body 200, which can also avoid interference with the telescopic lamp body 300.
