[0026] like Figure 1-6 As shown, the top of the reinforcement box 6 is located at a position corresponding to the worm 11 and is rotatably connected to a knob 12. One end of the worm 11 passes through the top wall of the corresponding reinforcement box 6 and is fixedly connected to the knob 12. The knobs 12 on both sides are rotated to drive the corresponding worm 11 to rotate, thereby driving the worm wheel 8 and the bidirectional screw 7 engaged therewith to rotate, thereby driving the sliders 10 and the bottom plate 13 at both ends to move in opposite directions, thereby increasing the overall support surface and improving the stability of the placement rack 1.
[0027] like Figure 1-6As shown, both sides of the top front end of the placement rack 1 are fixedly connected with fixing blocks 16, and slots 17 are opened at the front ends of the fixing blocks 16.
