description The utility model discloses a self-locking type cylindrical thread clamping device which comprises a clamping head, a tooth block and a pin shaft, a U-shaped groove is formed in the clamping head, the tooth block is rotationally connected in the U-shaped groove through the pin shaft, the bottom of the tooth block is an arc surface, friction teeth are arranged on the top of the tooth block, and the tooth block is connected with the pin shaft through the pin shaft. And an arc groove in sliding fit with the arc surface is formed in the bottom of the mounting groove. The direction of the clamping force can be changed along with the increase of the torque, so that the torque is improved, and the surface of a part is protected from being scratched. The clamping device is simple in structure and convenient to install, has the advantages of being convenient to operate, large in clamping range, large in torque, free of scratching the surface of a part and the like, and greatly improves working efficiency and product q
