Diesel injector pressure chamber pressure measuring device

The utility model provides a diesel injector pressure chamber pressure measuring device, which relates to the technical field of diesel injectors and comprises a base and a connecting pipe, rectangular blocks are symmetrically and fixedly connected to the upper surface of the base, and threaded rods penetrate through the outer surfaces of the two rectangular blocks in a threaded manner. And clamping blocks are rotationally connected to one ends of the two threaded rods correspondingly, and protection pads are arranged on the outer surfaces of the two clamping blocks correspondingly. According to the fuel injector fixing device, the connecting pipe is fixed through the supporting rod, the clamping blocks can conveniently move front and back through the threaded rod, the rotating handle and the guide rod, the fuel injector can be fixed through matched use of the clamping blocks, rigid extrusion cannot be generated on the fuel injector when the clamping blocks clamp the fuel injector through the protection pad,
