description The utility model belongs to the technical field of blood sampling devices, and particularly relates to a peripheral blood sampling device which comprises a blood sampling tube, a push rod, a pressing plate, a blood sampling unit and a limiting unit. When peripheral blood of a patient needs to be collected through the blood collection unit, a blood collection tube is held to drive a positioning ring to be aligned with a puncture position, then a pressing plate is pressed to drive a push rod to move, and the push rod moves to drive a piston to move and drive a first spring to stretch; when the piston moves to the top ends of the limiting ring and the blood sampling port, the pressing plate is continuously pressed to push the blood sampling port to move, so that the blood sampling port is in contact with the skin of a patient to puncture a blood vessel, then the pressing plate is pressed, the piston reversely moves under the reset action of a first spring, and negative pressure is generated to extract a blood s
