Staple remover

Technical Field

The utility model relates to the technical field of office supplies, in particular to a staple remover.

Background

In daily learning work, files are often classified and sorted in small batches and bound by a stapler, however, after the binding is finished, the situation that the files are summarized wrongly or the files need to be added often occurs, the bound staples need to be removed for the next processing, and at the moment, the staples need to be removed by a staple remover. The existing nail puller is basically in a clamp shape, the tail ends of two clamp arms are hinged by a pin shaft, the front ends of the clamp arms are provided with two nail teeth, the nail teeth of the two clamp arms can be mutually occluded, and the nail teeth are pressed into spaces between the nail feet of a staple and paper forcibly when the nail puller is used, so that the nail feet are deformed, and the staple is removed. In the process, the paper can be subjected to normal pressure acted on the plane of the paper by the nail teeth, so that the paper is possibly damaged and the use is labor-consuming. Aiming at the defects, the staple remover is designed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems that a staple is labor-consuming to use and easily damages paper documents.

In order to achieve the purpose, the utility model adopts the following technical scheme: a staple remover comprises a base unit, a wane unit, a pin shaft and a V-shaped spring. The base unit and the wane unit are arranged on two sides of the V-shaped spring and hinged through the pin shaft.

The base unit comprises a base, two fork pins and two pin hole seats; two fork needles are fixed on the front section of the base; the pin hole seat is arranged on the upper side of the base close to the fork pin; the fork needle is fixed at the front end of the base and used for being inserted into a semicircle formed by staple legs and guiding the deformation direction of the staple legs;

the wane unit comprises a wane head, a pressure plate and two pin hole seats; the wane is L-shaped, the short edge is a wane head, and the long edge is a pressing plate; the warping head is used for being inserted into a gap between the staple long rod and the paper and jacking up staples; the pressing plate is used for pressing; one end of the pressure plate, which is close to the warping head, is provided with two pin hole seats; a certain angle is formed between the warping head and the pressing plate;

the pin shaft is used for hinging the base unit, the wane unit and the V-shaped spring;

the V-shaped spring can be pressed to drive the rocker to return.

Detailed Description

The technical solution of the present patent will be further described in detail with reference to the following embodiments.

The utility model adopts the following technical scheme: a staple remover comprises a base unit, a wane unit, a pin shaft and a V-shaped spring. Base 1 and wane 5 are articulated through round pin axle 2, install V type spring 3 between two pinhole seats 4 of articulated department, are fixed with fork needle 8 on base 1 is close to the front end of round pin axle 2, are fixed with wane 6, rear side at wane 5 front sides and are clamp plate 7.

The base unit comprises a base 1, two fork needles 8 and two pin hole seats 4; two fork needles 8 are fixed on the front section of the base 1; the pin hole seat 4 is arranged on the upper side of the base 1 close to the fork pin 8; the fork needle 8 is fixed at the front end of the base 1 and used for being inserted into a semicircle formed by staple legs and guiding the deformation direction of the staple legs; the distance between the two fork needles 8 is between 10mm and 12 mm; the wane unit comprises a wane head 6, a pressure plate 7 and two pin hole seats 4; the wane unit is L-shaped, the short side is a wane head 6, and the long side is a pressing plate 7; the warping head 6 is used for being inserted into a gap between the staple long rod and the paper and jacking up staples; the pressing plate 7 is used for pressing; one end of the pressure plate 7 close to the warping head 6 is provided with two pin hole seats 4; a certain angle exists between the warping head 6 and the pressing plate 7, and the angle is 100-170 degrees; the pin shaft 2 is used for hinging the base unit, the wane unit and the V-shaped spring 3; v type spring 3 can be in pressing drive behind wane 5 return.

The whole device working process is as follows:

when the staple needs to be detached, the fork pins are firstly aligned to gaps formed between staple pins and paper, then the pressing plate is pressed to adjust the position of the warping head, the warping head is aligned to be inserted between the long edges of the staple and the paper, the pressing plate is pressed forcibly, the warping head is moved to move the staple upwards, the staple pins are reversely deformed under the guide of the fork pins to further detach the staple, and after the pressing plate is released, the warping plate returns to the original position under the elastic force of the V-shaped spring.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all technical solutions that fall under the spirit of the present invention fall within the scope of the present invention.
