The invention belongs to the field of material attaching devices, and specifically relates to a permanent magnetic chuck. The permanent magnetic chuck comprises a housing, wherein two circular holes are formed in the housing and are separated through a separating block; a rotating shaft is mounted in each circular hole; two stripy magnets are embedded in parallel into the rotating shafts; the sidesurfaces of the two stripy magnets are separated through a first magnetism separating sheet; the stripy magnets at two sides of the first magnesium separating sheet are in opposite magnetizing directions; two flat bodies are arranged at two sides of the rotating shafts in the magnetizing direction of the stripy magnets; two embedding blocks are embedded into the housing and are separated througha second magnetism separating sheet; the upper surfaces of the two embedding blocks are inner wall surfaces of the circular holes, and the lower surfaces of the two embedding blocks are attaching surfaces; the first magnetism separating sheet and the second magnetism separating sheet are manufactured through magnetism isolation materials; the rotating shafts, the separating blocks and the embedding blocks are manufactured through magnetism conducting materials. The permanent magnetic chuck has the beneficial effects that the outline dimension of the stripy magnets can be reduced, so that the product is lightweight; the manufacturability of the product is improved, and moreover, the manufacturing cost is decreased; in addition, the utilization efficiency of the stripy magnets can be improved.
