The invention discloses a holding clamp type lifting device which comprises two self-weight clamping mechanisms connected to the front end and the rear end of a hinge shaft and lifting lugs arranged at the upper ends of the two self-weight clamping mechanisms. The self-weight clamping mechanism comprises two pulling plates and two clamp arms, one ends of the two pulling plates are hinged together through a first hinge shaft, the middles of the two clamp arms are hinged through a second hinge shaft, the upper ends of the two clamp arms are hinged to the other ends of the two pulling plates through two third hinge shafts respectively, and the lifting lug is arranged in the middle of the first hinge shaft. The lifting device is simple in structure and convenient to maintain, the pulling plate and the clamp arm are connected through the first hinge shaft, the second hinge shaft and the two third hinge shafts, the device is opened under the action of pressing force and closed and clamped under the action of dead weight during lifting, automatic opening and closing can be achieved, a coil stock workpiece is conveniently clamped or loosened, and the lifting operation efficiency is high.
