A depth measurement device is slidably installed in the variable-diameter through-hole 5 . Rod 10, the top of the depth measuring rod 10 is opposite to the bottom of the measuring head 8, the upper end of the depth measuring rod 10 has a boss 9 corresponding to the variable diameter through hole 5, the outer diameter of the boss 9 is smaller than the inner diameter of the upper section of the variable diameter through hole 5 , greater than the inner diameter of the lower part of the variable diameter through hole 5, a spring 4 is set between the bottom end of the measuring head 8 and the top end of the depth measuring rod 10, and the design of the spring 4 is determined according to the free stroke of the gauge 1. In order to realize one meter with multiple functions and multiple depth measurements, the depth measuring rod 10 is a segmented docking type, and its docking method adopts a plug-in or threaded connection. In the figure, the calibration seat 11 is used to calibrate the range of the scale. When in use, hold the measurement positioning seat 6 so that the measurement positioning plane is in contact with the upper end of the calibration seat 11, so that the measuring head of the depth measuring rod 10 is contacted with the theoretical bottom surface and then positioned along the measurement. The seat 6 moves upwards, the depth measuring rod 10 compresses the spring 10 and contacts the measuring head of the gauge 1, the gauge 1 displays the value, completes the reset action, and then enters the measurement state.
