Then, the connecting frame 6 is pulled to drive the connecting shaft 11 to move to one side through the first positioning groove 14 inside, and the connecting shaft 11 drives the external pressure roller 2 to move. When the pressure roller 2 is attached to one end of the base material 1, it can press the base material 1 tightly, making the base material 1 fit more closely, preventing the appearance of air bubbles, and achieving the automatic pressing of the base material 1 when attaching it.
[0030] Embodiment 2: One side of one end inside the connecting frame 6 is fixedly connected with a second positioning groove 15.
