Finally, the left and right sides of the gauze 3 are folded toward the inside of the edge pressing groove 6 and clamped and fixed by the edge pressing strip 7, so as to achieve the fastening of the left and right sides of the gauze 3. After the panel 2 and the base plate 1 are docked and installed, the installation process is completed.

[0029] The utility model sets a curling mechanism and a pressing mechanism, and moves the curling roller 4 to move inside the curling groove 5, driving the gauze 3 to be embedded inside the curling groove 5, so that the gauze 3 is continuously rolled up and clamped between the curling roller 4 and the curling groove 5, so as to achieve the fastening of the upper and lower sides of the gauze 3. Under the action of the reverse force, the gauze 3 is in a taut state and is tightly attached to the inner side of the bottom plate 1 to ensure that it is straight and wrinkle-free. Then, the left and right sides of the gauze 3 are folded into the pressing groove 6, and are clamped and fixed by the pressing strip 7, so as to achieve the fastening of the left and right sides of the gauze 3. After the panel 2 is docked and installed with the bottom plate 1, the installation process is completed, and its sealing and stability are strong, and the gauze 3 is not easy to be loose, wrinkled, or fall off.
