[0003] For example, patent publication number CN216183883U discloses a vacuum suction structure for a flatbed inkjet printer, comprising a carrier plate with suction holes defined on its top surface and a cavity defined within it. An electric hydraulic push rod is bolted to the top of the cavity, and the top output end of the electric hydraulic push rod is mounted to a fixed plate via a mounting bracket and bolts. A pin corresponding to the suction hole is screwed to the top of the fixed plate. This vacuum suction structure for a flatbed inkjet printer has drawbacks.
