Rotary Clamp Device

 Rotary Clamp Device is installed on the wellhead, when the Kelly is not on the wellhead (inside the rotary table), it may give drill pipe a forward torque or backward torque, and to finish forward rotation or backward rotation and the hole reaming operation instead of the Kelly. The merits of it are: it can be directly installed on the wellhead or casing on the drill tools without unleashing the drill tools.
