Novel power slip

The utility model relates to a novel power slip used in the drilling operation. The power slip comprises a connecting rod, a rotating arm, a hoisting frame, a slip wedge body, a slip insert, slips, a slip base, a large quadrel, a hoisting frame lifting power cylinder, a connecting rod rotating power cylinder and the like. A lifting oil cylinder piston rod is connected with the hoisting frame; a cylinder body is connected with a support saddle (or in reversed connection); and the support saddle is connected with a rig floor. During the well drilling process, when a drilling rod is connected, the slips rotate under the action of the connecting rod rotating power cylinder, and three (or more) slips are folded to clasp the drilling rod; and then a lifting oil cylinder acts, and the hoisting frame moves downwards, so that the slip wedge body is forced to push a drilling column to be centered first, and then the slip wedge body moves downward along the inner conical surface of the slip base and folds until the dril
