At this time, after the driving slider 41 linearly moves a predetermined distance along the sliding rod 22 from the initial position, the other end of the cable to be tested contacts the abutting rod 42. The free part length of the cable to be tested between the first wire column group 321 and the second wire column group 322 is calculated by a background program by transmitting a signal through the displacement sensor 51 and reflecting the signal to the displacement sensor through the position detection plate 413 to acquire the moving distance information of the sliding seat 41. The number of posts 32 wound around the cable to be tested is detected by the optical fiber sensor 52, and the fixed portion length of the cable to be tested is calculated from the number of posts 32 wound around. Therefore, the sum of the free part length and the fixed part length of the cable to be tested is the whole length. The cable length measuring device provided by the invention can accurately measure the length of the cable to be measured, can realize semi-automation and automatic detection by matching with automatic equipment while improving the measuring precision, greatly improves the measuring efficiency, and effectively avoids the problems of low efficiency, poor precision, easy error and the like caused by manual measurement.
