The utility model relates to a terminal pressure maintaining and flow dividing device which comprises an installation cavity, a main pipeline and branch pipelines. The mounting cavity is connected with the negative pressure device through the main pipeline, the multiple branch pipelines are communicated with the interior of the mounting cavity, each branch pipeline is provided with an air valve switch, and a soft suction cup is fixed to the adsorption end of each branch pipeline. According to the terminal pressure maintaining and flow dividing device, the main pipeline is used for controlling circulation of total air pressure, the branch pipelines are used for controlling circulation of branch air pressure, when the terminal pressure maintaining and flow dividing device is used, air valve switches of the branch pipelines can be controlled, it is ensured that enough adsorption air pressure is output, a workpiece is stably adsorbed to a detection jig, and accuracy and reliability of measurement are ensured.
