As the screw rod 18 rotates, the movable frame 15 moves back and forth with the cooperation of the guide rail 14 and the slide seat 13, and then the movable frame 15 drives the tube pressing plate 19 to move back and forth, so that the tube pressing plate 19 gradually approaches the six-core rotor 10, or moves away from the six-core rotor 10, thereby squeezing or loosening the catheter, so that the squeezing force between the catheter and the six-core rotor 10 can be adjusted, and then the six-core rotor 10 is driven to rotate by the first motor 8.
