Abstract
The invention discloses a clamping tool with a worm gear and a worm. The clamping tool comprises an installation cavity. Two clamping arms which are directly oppositely arranged are installed in the installation cavity. The heads of the clamping arms forwards extend out of the installation cavity. Two reset-guidance devices which are directly oppositely arranged are installed in the installation cavity and connected with the clamping arms respectively. A clamping arm inner pressing rod is arranged in the installation cavity. The front end of the clamping arm inner pressing rod is aimed at the tail portions of the clamping arms. When advancing, the clamping arm inner pressing rod drives the clamping arms to clamp oppositely and driven by a jacking-lifting device.
