A larger lamp body installation area when working and a smaller occupied space when not working can be achieved.
[0006] Preferably, the outer end of the folding support rod is rotatably connected to the folding arm through a rotating bracket, the rotating bracket is provided with a limit pin shaft plugged into the connection between the folding support rod and the folding arm, and a plurality of lamp bodies are evenly spaced on the folding arm, which can further expand the installation area of the lamp body.
[0007] Preferably, the folding support rod is provided with a limit clamping plate for clamping the folding arm, which can limit the folding arm in the folded state to prevent accidental unfolding.
[0008] Preferably, 3M foam is provided on the inner side of the limit card plate to reduce the swing of the folding arm.
[0009] The utility model has the advantages of simple and reasonable structural design, folding and telescopic functions, convenient opening and closing, and effectively reducing the occupied space when not in use. BRIEF DESCRIPTION OF THE DRAWINGS
