[0039] When the active cylinder 320 is extended, the gas in the piston cylinder 350 is extracted through the first air pipe 340, so that the piston plate 360 slides into the piston cylinder 350, so that the rubber belt 310 connected with the piston plate 360 is pulled, and since the piston cylinder 350 and the piston plate 360 are both provided with two and symmetrically located on both sides of the insertion hole 211, so that the two ends of the rubber belt 310 are pulled. After the blood needle is inserted into the blood vessel, the active cylinder 320 is controlled to be shortened, and the gas in the active cylinder 320 is released into the piston cylinder 350, at this time the piston plate 360 is pushed, so that the two piston plates 360 are close to each other, so that the rubber belt 310 is released, at this time the elastic pull rope 311 pulls the rubber belt 310 to make the rubber belt 310 form an annular diameter, so that the rubber belt 310 is away from the arm, so that the blood can be drawn subsequently. After blood is drawn, the arm can be drawn out of the insertion hole 211.
