Abstract

The utility model relates to a strong clamping force file, comprising two clamping plates, a spring and a spring shaft. The utility model is characterized in that the clamping points of the clamping plates are bent inward from the top to form hook-shaped plates which are sheathed with spring material sleeves and are provided with a definite included angle or a nearly parallel shape with the original clamping plates. While being used, the file alters the shortage of the original file with loose clamping force to make paper sheets drop and is not easy to damage paper sheets when files, paper sheets or newspapers are clamped.

Description

Strong-clamping force file

The utility model belongs to a kind of stationery, particularly a kind of strong-clamping force file.

At present, various file a great varietys, outward appearance is also various informative, can be used to press from both sides file, paper, newspaper, picture page etc., but existing all kinds of files generally only limit to the difference of outward appearance, big difference is not arranged on its function of use, and when accompanying more paper number of pages, its folder power is limited, Chang Yi makes paper slippage from folder, and influence is used.

The purpose of this utility model is to provide a kind of strong-clamping force file, and it can make the clamping force raising of folder and not damage the page file, also can make file, newspaper file as required simultaneously, and various ways such as painting folder are the regeneration products of modern file.

The technical solution of the utility model: a kind of strong-clamping force file, comprise second splint, spring and spring shaft, second splint connects as one according to spring and spring shaft, the clamp mouth part that it is characterized in that said clamping plate by the top curve inwardly be collude tabular, and crooked colluding of coming is with the elastomeric material cover on the plate, colluding that this bending is come has certain angle or be intimate parallel shape between plate and former clamping plate.

Above-mentioned said powerful file outward appearance can be designed to various forms, as file, newspaper binder, painting folder etc., also can constitute single folder clipboard form by monolithic clamping plate and clipboard, and the width of its clamping plate also can be according to the needs of different files and difference.

Using method of the present utility model: when hand is exerted oneself by the plate end of clamping plate, the folder mouth opens, the required paper document that sandwiches sandwiches in it, the folder mouth that contact paper this moment no longer is the lower end of clamping plate, but its bending comes and is with the plate that colludes of resilient sleeve, and the clamping force that this moment, spring was executed elastic force in addition makes frictional force increasing between paper and folder mouthful, makes the clamped and difficult drop-off of folded paper, folded paper more for a long time, this kind effect is obvious further.

Superiority of the present utility model is: it is not tight 1, to have changed original file folder power, makes the caducous shortcoming of paper; 2, holding paper open, not fragile page when file, newspaper; 3, simple in structure, be easy to make, be convenient to promote the use of.

Further specify present technique below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of a slice clamping plate of the related file of the utility model.

Fig. 2 is the overall structure side view of the related file of the utility model.

Wherein 1 is clamping plate, and 2 is spring, and 3 is spring shaft, 4 the plates that collude for clamp mouth part, and 5 is resilient sleeve.

Embodiment: a kind of strong-clamping force file (seeing Fig. 1 and Fig. 2), comprise second splint 1, spring 2 and spring shaft 3, second splint 1 connects as one according to spring 2 and spring shaft 3, the clamp mouth part that it is characterized in that said clamping plate is curved inwardly to be by the top and colludes plate 4 shapes, and crooked colluding of coming is with elastomeric material cover 5 on the plate 4, and the plate 4 that colludes that this bending is come is intimate parallel shape (see figure 2) with former clamping plate 1.

Claims

1, a kind of strong-clamping force file, comprise second splint, spring and spring shaft, second splint connects as one according to spring and spring shaft, the clamp mouth part that it is characterized in that said clamping plate by the top curve inwardly be collude tabular, and crooked colluding of coming is with the elastomeric material cover on the plate, colluding that this bending is come has certain angle or be intimate parallel shape between plate and former clamping plate.
