Grounding grid test wire take-up and pay-off device

The utility model relates to the technical field of grounding grid test wire take-up and pay-off equipment, in particular to a grounding grid test wire take-up and pay-off device, and solves the technical problems that when the grounding grid test wire take-up and pay-off device is used, a test wire is generally taken up and paid off through a transmission shaft, in the take-up and pay-off process, the resistance of the bottom surface of the test wire possibly generates counterforce with the transmission shaft, and the test wire cannot be taken up and paid off. According to the technical scheme, the grounding grid test wire take-up and pay-off device comprises a take-up and pay-off device body, a rotating assembly, a take-up and pay-off assembly, a supporting assembly, a limiting assembly, a moving assembly and an energy supply assembly. According to the grounding grid test wire take-up and pay-off device, the resistance of the test wire and the transmission shaft can generate counterforce, continuous take-up
