The first hinge rod 25 is movably arranged in the movable groove 23, and a resistance plate 26 is hingedly connected to one end of the first hinge rod 25 away from the internal threaded ring 24. The inner side of the resistance plate 26 is connected to the winding member 2 by two second hinge rods 27, and the inclination directions of the first hinge rod 25 and the second hinge rod 27 are opposite. When the operator puts the winding drum on the winding member 2, the first hinged rod 25 is forced to slide along the inner wall of the movable groove 23 by rotating the screw rod 22. At this time, the first hinged rod 25 is deflected upward and causes the second hinged rod 27 to deflect upward, thereby pushing the contact plate 26 to move and contact with the inner wall of the winding drum, thereby facilitating the fixing of the winding drum on the winding member 2. Conversely, when the operator rotates the screw rod 22 in the opposite direction, the first hinged rod 25 and the second hinged rod 27 are deflected downward and drive the contact plate 26 to reset. At this time, the contact plate 26 and the winding drum are fixed, thereby facilitating the operator to replace the winding drum.
