The utility model discloses a bag clamping, feeding and air extracting device for a powder degassing packaging machine. The bag clamping, feeding and air extracting device comprises a fixed bottom plate, a first air cylinder and a guide sleeve. First air cylinders are symmetrically and fixedly connected to the fixed bottom plate. A bottom-layer moving plate is fixedly connected to a piston rod of the first air cylinder; a plurality of guide sleeves are symmetrically and fixedly connected to the bottom-layer moving plate; the side face air exhaust cover and the air exhaust connector are fixedly connected to the side face of the bagging pipe in a communicating mode, so that an external negative pressure device can keep a negative pressure air exhaust state at the opening position of the upper end of the packaging bag, the portion, containing particle materials, of the lower end of the packaging bag can keep an air exhaust sealing state, and meanwhile the opening position of the upper end can also keep a sealing
