description The utility model relates to the technical field of drilling rig equipment, and discloses a rotary drilling rig clamp holder mechanism which comprises a top plate, a second counter bore is upwards formed in the bottom end face of the top plate, a second hydraulic cylinder is fixed to the top end face of the second counter bore, and the bottom end of the output end of the second hydraulic cylinder is connected with a second adjusting rod. The bottom end of the second adjusting rod is rotationally connected with a middle plate, a second connecting rod is fixed to the bottom end face of the top plate, the second adjusting rod and the second connecting rod are distributed in a bilateral symmetry mode relative to the top plate, and the bottom end of the second adjusting rod is rotationally connected with the middle plate. When a new wellhead lifted by the clamping device is in a non-vertical state, the inclination angle of the bottom plate in the front-back direction is adjusted through the first hydraulic cylinde
