The support frame fixes the protection plate and the injection molding sheets therein through the inner opening.

[0009] Further, a closing plate is fixed to the front side of the support frame, and all the fitting partitions and injection molded sheets are fixed to the rear side of the closing plate. A fitting strip is fixed to the side of the fixing strip away from the support frame. The support frame cooperates with and closes the fitting plate and the injection molded sheet through the closing plate.

[0010] Further, reinforcing strips are fixed to both sides of the side connection strip, and both of the two reinforcing strips are fixed to the rear side of the support frame. A fitting groove is formed along the vertical center line on the rear side of the side connection strip.
