At this time, the fixing frame 6 fixes and limits the side of the aluminum strip 3 to prevent it from falling off. Then, the roller 16 is pressed against the outer wall of the aluminum strip 3. Then, the extension and retraction of the spring 11 enables the fixing frame 6 to adapt to different diameters of the aluminum strip 3. Then, by rotating the knob 20, the screw 19 drives the telescopic rod 21 to extend and retract, while the limiting frame 12 is adjusted according to the width of the aluminum strip 3. When the aluminum strip 3 is stretched for use, the aluminum strip 3 drives the roller 16 to rotate, which in turn drives the nickel strip 4 to stretch the spring 17. At this time, the extension and retraction of the spring 17 reduces the downward pressure of the roller 16.
