18. The magnetic attractive conjunction mechanism of rotating gripper in clamping device as claimed in claim 1, in which:
the sector type prism rotating gripper (11) made of magnetic or non-magnetic materials, which is installed in the flush socket with sector type recessed cylindrical sliding surface (8) of the clip jaw (10), which is made of magnetic or non-magnetic materials, to make coaxial relative rotation, and their cylindrical arc surfaces are sliding and tight contact to form a coupling surface, in which the magnetic structure is installed at one or two of the sector type prism rotating gripper (11) and the coupling surface of the flush socket with sector type recessed cylindrical sliding surface (8) of the clip jaw (10), along the sliding arc coupling surface, and the spiral hole (119) is placed at one or two of the both, for screwing in the screwed magnetic attractive conjunction mechanism with the horseshoe magnet, which is installed with the horseshoe magnet (20) and the non-magnetizer (112), to make the both attract and connect each other after coupling to form a closed magnetic circuit.
