Disclosed is a disc-type take-up and pay-off device for a ground wire. The disc-type take-up and pay-off device is mainly composed of seat frames on the two sides and a rotary shaft in the middle. The seat frames on the two sides are each composed of a shaft seat on the upper portion and at least two floor supporting bars fixed to the shaft seat; the two ends of the rotary shaft penetrate through the shaft seats on the seat frames on the two sides correspondingly, and an operation handle is connected with one end of the rotary shaft; a locating disc with inserting holes is fixed to one side of the rotary shaft, and a perpendicular hanging bar is at least fixed to the other side of the rotary shaft; the seat frames on the two sides form a support through the middle connecting rotary shaft, and the support enables the seat frames on the two sides to relatively extend and retract; four holes located on the same straight line are formed in the locating disc fixed to the rotary shaft, the diameter of the three large holes is slightly larger than that of a ground rod, and the diameter of the other small hole is slightly larger than that of a ground pin; and the perpendicular hanging bar fixed to the other side of the rotary shaft and the four holes located on the same straight line are located on the same plane. The disc-type take-up and pay-off device for the ground wire has the characteristics of being simple in structure, convenient to use and operate, capable of improving work efficiency and usage safety and the like.
