The described skewed slot of opening on the spoon is made as one at least, the end of opening spoon places on the box wall by return spring, and be connected as a single entity with the outer knob of box body, so that when pressing knob, make out skewed slot on the spoon promote bumping post and move within it, thereby driving slide plate moves, finish and unblank, afterwards, under the effect of return spring, make slide plate and open spoon to reset, in order to locking.

Described end one side of opening spoon last skewed slot is provided with vertical block face, and when not opening accurately depressed position spoon, slide plate is then blocked and can't move by this vertical block face because of the bumping post on it, thereby can't realize unblanking, and also can't allow others open spoon accurately by location aware.

Bumping post quantity on the described slide plate with open spoon and on skewed slot quantity corresponding, perhaps with open spoon and on skewed slot quantity and ornamental to open spoon quantity corresponding.

Link plate that is used for the open and close key on the described slide plate and the shell fragment correspondence on the box body are arranged on the below of lid slot, and the shell fragment on the box body is relative with the link plate end on the slide plate, so that can place the link plate below after making the key insertion and pressing shell fragment, lock thereby finish.

On the box body open the spoon can be provided with as required one or more, and one or more ornamental spoons of opening are set, so that when one or more accurately open spoon depressed position, slide plate is moved, unblank thereby finish, wrong by one or more ornamental spoons of opening, perhaps few during by the opening spoon an of correct position, all can not promote slide plate, thereby can't unblank.

Described key is a U-shaped pole, and its openend is fixed on the clad, and the other end is used to insert in the box and locks.

The utility model compared with prior art has following advantage and effect: adopt such scheme; solved that all kinds of bag of the prior art has only slide fastener or snap-fastener and the often stolen problem of article in the bag that brings; after this lock is installed; having only the owner of bag to know unblanks by spoon; push the wrong; how by or few by all unblanking; and when the position is opened spoon accurately and is known by other people; can readjust out spoon and ornamental position of opening spoon; it is stolen that all kinds of article in thereby effectively protection is wrapped are difficult for, and this device is suitable for being installed in all kinds of wrapping, and is not only simple in structure; theftproof performance is good; and unblank; it is all comparatively convenient to lock, and therefore, is a kind of ideal; practical reference position lock.
