  • Patent number: 7793900
    Abstract: An exemplary magnetic clamp holder used for a mechanical arm, includes a housing (21), a magnetic structure (22), and two positioning pins (25). The housing includes an attaching portion (211), and a joining portion (213) fixed to the attaching portion, the attaching portion and the joining portion cooperatively defining a receiving cavity (218). The positioning pins are disposed on the attaching portion of the housing. The magnetic structure is received in the receiving cavity. The magnetic structure includes a permanent magnetic module (223), an electro-magnetic module (225), and a magnetic shield plate (227) disposed between the permanent magnetic module and the electro-magnetic module. The electro-magnetic module is able to create a magnetic field for neutralizing a magnetic field created by the permanent magnetic module.
