The invention discloses a device for measuring the inner diameter of a through hole of a coupling. The device comprises a laser ranging probe, a measurement bracket, a digital display screen, a start button, a reset button, a USB charging port,and a support rod, wherein the digital display screen, the start button, the reset button, and the laser ranging probe form a high-precision laser ranging system, the start button is pressed down outside the coupling, The sum of vertical distances between the probe and the upper and lower inner surfaces of the coupling through hole can be detected by controlling the laser ranging probe, and then the inner diameter of the coupling through hole can be obtained by adding the height of the laser ranging probe. The device provided by the invention is convenient, economical and efficient to use, particularly aims at technical problems of small diameter, difficult operation and inaccurate reading of the small-specification tubing coupling, avoids problems of inaccurate manual measurement and inconvenient operation, and can improve efficiency of production detection.
