The feeding mechanism is used for continuously conveying, bending and discharging the LED lamp body, and the feeding mechanism is installed under the two feeding frames; through the feeding mechanism and the two feeding frames, a plurality of LED lamp bodies can be vertically stored, the LED lamp bodies are sequentially fed into the device shell, a bending piece continuously bends the LED lamp bodies, then the bent LED lamp bodies are discharged from an opening in the bottom of the device shell, and therefore the effect of continuous feeding, bending, conveying and discharging is achieved.
