Double thread earthing dop

The utility model discloses a double thread earthing dop which includes a metal blocking hook and a blocking slot module provided with a thread connector; the thread on the blocking slot module is a double-thread structure. The double thread earthing dop has the advantages of changing the thread connection on the blocking slot module into the double-thread structure, which can reduce the rotating times by a half under same thread stroke simultaneously when meeting same mechanical intensity and also reaching the target requirement of saving effort. Meanwhile, the double-thread structure is adopted and the two threads are simultaneously acted and strained when working; therefore, the requirement on the mechanical force and the requirement on the thread stroke can be satisfied, which can save half labor force.
