The rotating shaft 28 drives the rotating carrier 2 to rotate, and the rotating carrier 2 drives another rotating carrier 2 to rotate synchronously through the synchronously rotating transmission belt 27. Then, the adapted arc-shaped clamping plate 23 is rotated to the angle position corresponding to the catheter perforation 12, the rotating shaft 28 is stopped, and then the screw rod 32 is rotated. The screw rod 32 drives the two L-shaped push plates 3 to approach each other, so that the two L-shaped push plates 3 can squeeze the corresponding sliders 21 at the same time. The sliders 21 drive the arc-shaped clamping plates 23 to approach each other through the connecting rod 22. The two arc-shaped clamping plates 23 clamp and fix the catheter.
