A fixed base plate 33 is installed between one end of the elastic telescopic rod 32, and the fixed base plate 33 is clamped between the grooves of two adjacent fixing bars 11;

[0026] During operation, the chassis 1 fixes the card assembly 3 by the mutual engagement between the fixing strip 11 and the fixed base plate 33. The card assembly 3 is installed at both ends of the combiner platform unit 2, thereby fixing the combiner platform unit 2 to the chassis 1.

[0027] like Figure 2 、 Figure 3 and Figure 4 As shown, the fixed base plate 33 is provided with a card-mounting slot 331 near the side wall where the combining platform unit 2 is located, and two guide rods 4 are installed inside the card-mounting base plate 31.
