Ground wire needle holder

The utility model relates to a ground wire needle holder comprising a ground wire needle body. A drill or a ground wire needle is threadedly connected to the bottom of the ground wire needle body; a pincerlike ground resistor measurement liquid crystal display device is arranged at the middle portion of the ground wire needle body; and a ground needle handle is arranged on the ground wire needle body. Besides, a detachable percussion drill joint is arranged above the ground needle handle; and a ground wire connecting sheet is arranged at one side of the ground wire needle body. When there is a hard ground like a rocky ground or a cement ground, the drill can be changed, thereby realizing connection of the ground wire and the ground conveniently and rapidly. The ground wire needle holder is inserted into the hard ground; and after the work is completed, the drill can be rotated to pull out the ground wire needle holder under the circumstances that the ground wire needle holder is difficult to be pulled out. According to the utility model, the pincerlike ground resistor measurement liquid crystal display device is used to measure a resistor and thus the ground resistor information can be get timely, thereby solving a problem that the connection ground wire position have to be selected again due to overlarge ground resistance. Moreover, the pincerlike ground resistor measurement liquid crystal display device can be assembled or disassembled freely; and when the drill is used, the device can be removed to avoid the interference.
