The utility model discloses a vacuum pipettor with a counting function, relates to the technical field of pipettors, aims to solve the problems that a gun body is inconvenient to place and fix, a suction head ejector is easy to touch by mistake, and the use times of the gun body cannot be counted, and is used for transferring liquid. A plurality of gun bodies can be hooked on the fixing plate through the upper limiting plate and separated through the fixing blocks, then the moving plate on the fixing rod is moved, the gun bodies are limited through the limiting mechanism, and the hooked gun bodies can be fixed and are convenient to place and fix; by arranging the first shielding mechanism, the suction head ejector can be shielded, and mistaken touch is prevented; by arranging an elastic telescopic mechanism, a shell, a second shielding mechanism, a counting key and a counter, when a suction head ejector is pressed, a second connecting plate and the elastic telescopic mechanism can be driven to move downwards,
