Abstract
The invention relates to a clamping tool with a worm gear, a worm and resetting pressure springs. The clamping tool with the worm gear, the worm and the resetting pressure springs comprises a mounting base. A mounting cavity body is arranged inside the mounting base. At least three clamping arms are arranged inside the mounting cavity body and are distributed uniformly in the annular direction. The heads of the clamping arms stretch out of the mounting cavity body in a forward mode, the middle parts of the clamping arms are hinged to the mounting base, and the same clamping arm ejection rod is arranged inside the mounting base behind the clamping arms in a penetrating mode. The front end of the clamping arm ejection rod is aligned to the tail portions of the clamping arms. When the clamping arm ejection rod moves forwards, the clamping arm ejection rod pushes the tail portions of the clamping arms to be relatively separated and pushes the heads of the clamping arms to be relatively clamped. The clamping arm ejection rod is driven by a jacking device provided with the worm gear and the worm. The clamping arm resetting pressure springs are arranged between the tail portions of the clamping arms and the inner wall of the mounting base respectively. The clamping arm resetting pressure springs push the tail portions of the clamping arms to be relatively clamped for resetting. By adopting the structure, bevel gear shafts with different diameters are clamped, the operation is easy, and the application range is wide.
