SEAL PRESSURE APPLIANCE FOR SEAL

Technical field

This present invention relates to the field of seal, more specifically, to seal pressure appliance coupling or attaching to upper part of seal.

Background art

In general seal, the seal is required to stamp by applying pressure simply as using groove formed around the central part in case of the personal seaKcolumnar seal) and groove formed on the front side in case of the rubber stamp (hexahedral seal).

Particularly, because the width of the columnar seal is narrow, finger pressure status of index finger which is the main finger pressure part is unstable, and it is difficult to completely realize the content of the seal with light finger pressure only.

In seals equipped with spring devices disclosed conventionally, the seals are typically composed of upper and lower body or inner and outer case connected by spring. In order to return the body or case to original state after movement, separate tensile spring and lifting means must be required. Such a body or case is a cause to increase the weight of the seal. Further, the series of devices are required to manufacture as the seal with a set of inner and outer part. The seal equipped with the spring device increase the complexity and cost of the manufature undesirably than general seal, and it is inconvenient to carry. Thus, it would be desirable to provide a pressure appliance miniaturized and lightened, which is not affected by outside appearance of seal.

It would be desirable to provide an independent appliance, which helps convenient use of general seal, not equipped with an auxiliary device. Disclosure of Invention

The present invention is described in detail by referring to the attached drawings as follows.

SEAL PRESSURE APPLIANCE COUPLING FIG. 2 is a section view of the components of a seal pressure appliance of the present invention for coupling to upper part a seal.
