Abstract:
A sucking device comprising:a suction head having at its extremity an opening arranged to suck an electronic component when a negative pressure is applied thereto; a hold-down center rod having an aperture, a conduit through which passes a gas supplied or discharged through said opening of said suction head, and a hold-down portion at its extremity adapted to be inserted into the interior of said suction head; a coil spring for imparting a biasing force to said suction head and said hold-down center rod; and a link lever interposed between said suction head and said hold-down center rod; wherein when said hold-down center rod is subjected to a force pressing down against said biasing force of said coil spring, said link lever pushes said suction head upward so that said hold-down portion of said hold-down center rod protrudes from said suction head.
