This present invention relates to the field of seal, more specifically, to seal pressure appliance coupling or attaching to upper part of seal. The seal equipped with spring device discloced conventionally, increase the complexity and cost of manufacture undesirably than general seal and it is inconvenient to carry. The present invention is to provide a seal pressure appliance miniaturized and lightened, and to provide an independent appliance, which helps convenient use of general seal. The seal pressure appliance is to couple or attach to upper part of seal, as which the pressure spring connected to the pressure plate is positioned into the cylindrical pin, or otherwise, which the inner device is enclosed into the inner device cover, and by composing the coupling means. When user stamp a seal, pressure status by hand is natural as which the pressure plate is rotatable, and stamping surface of seal is more effectively applied on stamping columns of paper. |
