Description

Clip

The present invention relates to be used for clip that clampings such as documentation are tied up.

Traditional file, known to the finger control actuating strut, make its contact-making surface expand the clip of opening and using, the dual little paper clip that is wound into ring-type, and elasticity plate body bending back formed contact chip up and down, other uses the clip etc. of certain pressing device (clamp device).

For above-mentioned clip, usually can produce clamping force, yet, when constituting large-scale clip, need contact chip to be expanded and open with very big operating physical force, also have the influence that to expand out or be subjected to action bars, the unfavorable condition that volume increases when making the file that utilizes this kind clip to tie up overlapping, for little paper clip since be with file the ring between, because of clamping force is little, there is the situation that thick file is difficult to clamp.

In addition, for the clip that must use above-mentioned pressing device, though easy and simple to handle, spend the labour less, also have sufficient clamping force, existence need be equipped with the problem of clip pressing device etc. in addition.

Therefore, the clip of the applicant's design opens the contact-making surface up and down that is closure state with external force relatively at every turn slightly, then with its power of returning from clamping traditional clip difference of file up and down, need not to use other device, make with pushing force that to expand the contact-making surface up and down open closed and obtain clamping force.

Therefore, the present invention is just in view of these problems that exist in above-mentioned traditional clip, and purpose is to provide a kind of need not to use clip fixed mechanism, simple in structure in addition, and is easy and simple to handle, can produce the clip of abundant clamping force.

For the present invention that achieves the above object is made up of clip body and thrust cap, described clip body has and is the loud-speaker shape from the both sides that formation has a kink of certain aperture and extends continuously, form in its end and have the holding piece up and down as the first couple of the opening of one first required aperture V; Described thrust cap have from the both sides that formation has a bending base portion of certain aperture extend continuously, near the position of the kink of clip body with described first pair up and down holding piece cooperates, form holding piece about the second couple with the 2nd required aperture Y narrower than the above-mentioned first required aperture V in its end; Each end from holding piece about in the of above-mentioned first pair forms towards the kink of clip body, the top ends that bends inwards simultaneously respectively; In addition, on every holding piece of holding piece about in the of described first pair, form two gathering sills arranged side by side respectively, on every holding piece of holding piece about in the of described second pair, form the guide pad that cooperates with described gathering sill respectively, described thrust cap is slidably located on the outside of clip body, and holding piece is approaching mutually in pressed state up and down to make described first pair.

Above-mentioned structure is owing to form clip body to make and expand the clamp clip up and down that open form becomes from its kink and become top expansion shape, thereby documentation to be tied up etc. successfully can be inserted clip inside.

When subsequently with thrust cap when the slide outside of clip body pushes, because the maximum opening that forms between clamp clip up and down in the insertion opening ratio clip body that forms between clamp clip up and down of this thrust cap is also little, thereby the clamp clip up and down of this thrust cap is slided before and after pushing to the clamp clip up and down of clip body from outside to inside, make that the clamp clip up and down of clip body is near each other in pressed state.
