Folding structure of plant lamp

The folding structure of the plant lamp comprises a fixing frame, a first mounting frame is movably arranged on one side of the surface of the fixing frame through a rotating shaft, and a second mounting frame is movably arranged on the side, away from the first mounting frame, of the surface of the fixing frame through a rotating shaft. Lamp tubes are fixedly arranged in the first mounting frame and the second mounting frame, a limiting mechanism is arranged on a rotating shaft where the first mounting frame and the second mounting frame are located, and the limiting mechanism comprises a locking screw, a limiting ring and a limiting block. The folding device is good in using effect, can be conveniently and rapidly unfolded when used, can be conveniently folded like a book when not used, can be conveniently stored and stored, meanwhile can limit the rotatable range of the first mounting frame and the second mounting frame through the limiting mechanism, and is convenient to use. Therefore, collision between
