FEEDING STRUCTURE AND FASTENING DEVICE

Disclosed is a feeding structure for a fastening device. The feeding structure comprises: a feeding mechanism, one end of which is a feed end, the other end is a discharge end, the feeding mechanism comprises a feed pipe and a conveying pipe that are communicated with each other, a mounting part entering from the feed end can be conveyed to the discharge end through the feed pipe and the conveying pipe. A propulsion mechanism is provided on one side of the feeding mechanism, with a central axis that is parallel to a central axis of the feed pipe. A material receiving portion for communicating the discharge end to receive the mounting part is provided on a shell of the propulsion mechanism, where a propulsion unit action of the propulsion mechanism can push the mounting part conveyed to the material receiving portion and mount same in a target position.
