When in use, the patient's arm is passed through the strap 1, and the indwelling needle infusion tube is placed in the needle tube groove 8, so that the arc-shaped pressing plate 7 fits the patient's arm. Then, by rotating the rotating cap 6, the rotating column 14 drives the winding roller 13 to rotate, so that the winding roller 13 rolls up the strap 1. Under the action of the limiting rod 11 and the limiting slot 12, the winding roller 13 can be prevented from bending when the strap 1 is wrapped around it. When the strap 1 is rolled up to fit tightly against the patient's arm, the arc-shaped pressing plate 7 is also tightly fitted with the patient's arm under the action of the strap 1. The indwelling needle infusion tube is pressed tightly on the child's arm, and then the movable screw 3 is rotated by rotating the rotating cap 12, so that the movable screw 3 drives the positioning plate 17 to descend, and the positioning plate 17 drives the latching tooth 18 to descend, so that the latching tooth 18 is pressed tightly against the strap 1 wound on the surface of the winding roller 13, so that the strap 1 is limited, so that the winding roller 13 is limited, and the strap 1 is prevented from being easily loosened. Through the above steps, the indwelling needle infusion tube can be firmly fixed on the child's arm, and the indwelling needle infusion tube can be prevented from falling off, causing the indwelling needle to shake and cause pain to the patient.
