Abstract
A clamping mechanism with a lead screw and reset magnets comprises an installation base. An installation cavity is formed inside the installation base. At least three clamping arms are arranged inside the installation cavity. The clamping arms are annularly and uniformly distributed. The heads of the clamping arms stretch forwards out of the installation cavity. The middles of the clamping arms are hinged to the installation base. One clamping arm ejector rod is arranged inside the portion, behind the clamping arms, of the installation base in a penetrating manner. The front end of the clamping arm ejector rod is aligned to the tails of the clamping arms. When the clamping arm ejector rod is moved forwards, the tails of the clamping arms are pushed to be separated relatively, and the heads of the clamping arms are clamped relatively. The clamping arm ejector rod is driven by an ejection device with the lead screw. One clamping arm reset magnet is arranged on the inner side of the tail of any clamping arm. The clamping arm reset magnets attract the tails of the clamping arms to be clamped relatively to be reset. By adopting the structure, bevel gear shafts of different diameters can be clamped, operation is easy, and the application range is wide.
