A connection frame 3 is installed at the bottom of the placement plate 2. Two fans 4 are symmetrically installed at the bottom of the connection frame 3. The air inlets of the two fans 4 are located inside the connection frame 3. When the fans 4 operate, suction will be generated in the ventilation holes 5 on the placement plate 2, and the printing paper will be flatly adsorbed on the placement plate 2.

[0020] As Figure 2 and Figure 3 shown, fixed frames 6 are symmetrically installed inside the digital printer housing 1. The top ends of the two fixed frames 6 are both slidably connected with connecting rods 8. Connecting blocks 9 are installed at the bottoms of the two connecting rods 8.
