Cable length-measuring device

The utility model discloses a cable length-measuring device, and belongs to the cable length-measuring device technical field; a technical scheme is that the cable length-measuring device comprises a rack; the device is characterized by arranging a roller positioning mechanism and transmission mechanism from top the bottom of the rack; the beneficial effects are that the cable length-measuring device is less in measuring error, can well solve the deviation problems between a cable real usage length in a construction field and a graph paper, and a positioning roller and a transmission roller are designed so as to solve the sliding, escaping and inversion phenomenon in contact type measurement; an electronic stopwatch and a sensor can improve cable length measuring accuracy; the cable length-measuring device is simple in structure, easy in operation, only one person is needed to pull one end of a to-be tested cable so as to complete the measurement, thus saving labor and time; the cable length-measuring device is suitable for mass cable lengths measurement.
