Description
Technical field
The present invention relates to a kind of seal, more particularly to a kind of wireless remote controllable type intellectuality seal.
Background technology
Seal is the legal determination thing of unit right, unit operation in produce legal document on need it is with an official seal affixed,
General seal all can first be stained with pigment and stamp again, non-sticky pigment, stamp can present after plane it is concavo-convex be referred to as steel seal, some are prints
In the wax printing on wax or sealing wax, on envelope.Making material has metal, wood, stone, jade etc..Seal includes official seal, finance
Diversified forms, the especially official seals, finance seal, contract chapter etc. such as chapter, contract chapter, private signature play in socio-economic activity
Very important role, it can produce legal effect very high, represent the power of government offices, group, enterprises and institutions etc.
Profit and legal will, while serious legal liabilities are also taken on, therefore, the keeping and use of seal are all very strict.
With continuing to develop for society, find that traditional seal has many defects in daily activity, specifically such as
Under, 1) existing seal accurately says to be exactly individual " a slow-witted chapter ", it is impossible to user is recognized, cannot more differentiate whether document can cover；
2) use process of the seal before adding a cover cannot be traced, it is impossible to which the use to seal forms effective control, usually because right
The event that the mismanagement of seal and causing covers steathily, cover more occurs, and unnecessary trouble and law, warp is brought to seal person liable
Responsibility in Ji, this kind of case has socially emerged in an endless stream；3) when the management appearance carelessness of seal is lost or be stolen, intentionally
People can pretend to be the identity of seal person liable that agreement or the conjunction coordinated files unfavorable to seal person liable are signed using seal, very
To delinquent file is signed, this can cause greatly to threaten and cannot bear legal responsibility to seal person liable, and existing
Seal the occurrence of cannot evade this kind of again.
Therefore, applicant proposes a kind of wireless remote controllable type intelligence after the above mentioned problem for having carefully studied seal presence
Seal can be changed.
The content of the invention
In order to solve the above problems, it is an object of the invention to provide a kind of wireless remote controllable type intellectuality seal.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of wireless remote controllable type intellectuality seal, including seal installation pedestal and inner hollow press handle, it is described
