Simple PID (Proportion Integration Differentiation) operation table

The utility model relates to the technical field of PID operating tables, and discloses a simple PID operating table which comprises an operating table body and moving wheels, a connecting block is fixedly connected to the bottom of the outer side face of the operating table body, an inserting rod is movably connected to the outer side face of the connecting block in an inserted mode, and a hand pull ring is fixedly connected to the outer end of the inserting rod in an inserted mode. The bottom of the outer side face of the operation table body is fixedly connected with a shell. According to the simple PID operation table, the electric-hydraulic push rod can indirectly drive the moving wheels to move downwards until the moving wheels extend out of the interior of the shell downwards, so that the outer surfaces of the moving wheels are tightly attached to the ground, meanwhile, the lower surface of the operation table body is separated from the ground, then the electric-hydraulic push rod is immediately closed
