the first air cylinder (241) and/or the second air cylinder (243) are/is connected to the side surface of the discharging channel (210);

the discharging channel (210) is provided with a first detection switch (216) and a second detection switch (217) for detecting the rivet (250), the first detection switch (216) corresponds to the first feeding port (211), and the second detection switch (217) corresponds to the first discharging port (212);

two rivet receiving openings, namely a first rivet receiving opening (221) and a second rivet receiving opening (222), are arranged on the reversing block (220), the first rivet receiving opening (221) is communicated with a first discharging pipeline (223), the first discharging pipeline (223) is communicated with a first compressed air interface (225), the second rivet receiving opening (222) is communicated with a second discharging pipeline (224), and the second discharging pipeline (224) is communicated with a second compressed air interface (226);

the first detection switch (216) and the second detection switch (217) feed back detection information to a controller, and the controller controls the operation of the first cylinder (241), the second cylinder (243) and the third cylinder (227);

the third limiting part (215) is a third limiting rod.
