Portable adjacent component level difference calibration detection instrument

The utility model relates to a portable adjacent component horizontal difference calibration detection instrument, and belongs to the technical field of measurement and test. The instrument comprisesa button, a magnet, a balancing weight, a push rod, a resin conduit with an open cavity port, a spring, a sealing rubber ring and a spiral hose, magnets are arranged at the bottom of the instrument for adsorbing steel materials; the balancing weight is used for weighting the instrument to lower the gravity center, the pushing rod is a spiral rod piece, the volume of liquid in the resin guide pipecan be controlled through spiral advancing and retreating, the spiral hose is used for communicating the two devices, the datum line and the scale marks marked on the resin guide pipe facilitate observation of the relative difference value of the liquid level, and opening and closing of the open cavity port can be achieved through the button, the spring and the rubber ring. The instrument can accurately detect the componen
