Description

Flat needle electric stapler

Technical Field

The utility model belongs to the technical field of the stapler technique and specifically relates to an electronic stapler of flat stitch.

Background

Staplers are widely used in the home and office environment as a stapling tool. The working principle of the existing common stapler is as follows: when the end cover of the stapler is pressed with force, the ejector, the needle and the fixture rotate around the connecting pin; along with the continuous application of strength, the top can rotate to break away from its natural state, and the top can do the approximate up-and-down motion of slightly being greater than a needle height, end cover spring compression, shell fragment compression about the connecting pin about this moment, can drive the downward motion of needle thereupon, and the needle can contact the paper of work plane after moving certain distance to pass the paper and can touch the mould afterwards under the effect of human power, the syringe needle is crooked, thereby realizes penetrating between needle and the thing and binds.

Since the ordinary stapler increases the thickness of the bound object due to the bent portion of the legs after bending the legs of the staple, and the bound object is liable to slip off, the related practitioners have developed a flatbed stapler to flatten the bent legs of the staple and reduce the thickness caused by the bent legs. The existing flat-stitch stapler is shown in a structure form as a flat-stitch stapler with a needle groove sheet track structure in chinese patent No. CN102019784A, and a flat-stitch device mainly comprises a movable plate and a needle groove sheet, wherein the movable plate is pivoted on a base, the movable plate can be pivoted on the upper base, and when a user presses a pressing handle component to drive a needle box component to pivot downwards, and when a staple is struck out from the needle box component, the movable plate pivots downwards along with the needle box component relative to the base, and a groove sheet accommodating hole is formed in the movable plate; the needle groove has a functional area on its top surface for leveling the needle and extending into the groove receiving hole of the movable plate, and non-functional areas on both sides of the needle groove. When binding, the paper is placed on the movable plate, the staple cartridge component drives out the staple to pierce the paper, the movable plate moves downwards until the movable plate is flush with the staple groove piece, and the pin of the staple is flattened through the functional area in the staple groove piece.

Although the existing flat-stitch stapler solves the problem of the bending height of the legs, because the papers are placed on the movable plates for binding, the upper needle box assembly and the lower movable plate can move, so that the papers are unstable in the binding process and are difficult to fix, the papers are always kept at one position, the phenomenon of binding deviation of the staples is caused, the binding effect is poor, and the expected binding effect of a user can not be achieved. Meanwhile, due to the structural limitation of the functional area of the slot sheet, the binding capability of the existing stapler using 1/4 inch (or 24/6 &26/6) staple is difficult to break through the technical problem of maximum binding of the number of sheets with the thickness of 3mm, and the application range is limited.

The flatting mechanism assembly 50 is thus used to automatically and effectively flatten the legs 4 of the staple 3, and the upper surface of the slot 53 is fixed, so that the working plane on which the bound object is placed on the slot 53 is kept stationary, and the bound position of the bound object is basically kept, which helps to prevent the bound object from moving unstably, and the legs 4 are flattened by the upward pressing of the flattening piece 54.

In this embodiment, the flatneedle electric stapler further includes a housing 8, the housing 8 being disposed above the base 1, the transmission mechanism 10 and the driving assembly 60 being accommodated between the housing 8 and the base 1.

In this embodiment, the flatbed needle mechanism assembly 50 further includes a guiding portion 51 and a base 56, the guiding portion 51 extends from the base 56 to the needle pressing mechanism assembly 2, the pressing member 54 extends from the front end of the base 56 to the direction of the nail groove 530, the base 56 can be connected with the guiding portion 51 and the pressing member 54 in a transmission manner, the guiding portion 51 is rotatably connected to the base 1, when the guiding portion 51 rotates, the pressing member 54 is driven to ascend or descend, and the nail groove member 53 on the outer side is kept stationary, so that the working plane of the binding object can be kept stable.

In the present embodiment, the staple groove 530 is provided with a pair of inclined guide surfaces 531 and notches 533, the notches 533 penetrate the guide groove 532 and the outside, the inclined guide surfaces 531 are symmetrically and obliquely provided on both side walls of the staple groove 530, the inner diameter of the notches 533 gradually decreases from the outside to the inside, the inclined guide surfaces 531 are disposed opposite to the legs 4 of the staple 3 at the staple outlet 411, when the staple 3 is pressed against the inclined guide surfaces 531, the inclined guide surfaces 531 are adapted to bend the legs 4 of the staple 3, the legs 4 of the looper extend along the inclined guide surfaces 531 to the guide groove 532, the pressing member 54 faces the legs 4 protruding from the inclined guide surfaces 531, and the pressing member 54 presses the protruding legs 4 in the horizontal direction so that the legs 4 of the staple 3 are horizontally attached to the back surface of the bound object, as shown in fig. 13 to 14.

In other words, when the legs 4 of the staple 3 are pressed against the inclined guide surfaces 531, the inclined guide surfaces 531 are adapted to bend the legs 4 and support a part of the bent legs 4, and another part of the bent legs 4 protrudes from the inclined guide surfaces 531 and extends toward the guide grooves 532, so that the pressing member 54 contacts and presses the bent legs 4 when moving upward, and if the bent legs 4 do not protrude, the pressing member 54 cannot contact the legs 4, and even cannot press the legs 4. That is, the legs 4 of the staple 3 are bent by the inclined guide surface 531 to form the vertical sections 5 and the bending sections 6, the bending sections 6 integrally extend from the vertical sections 5 along the inclined guide surface 531, the bending sections 6 are provided with the protruding sections 7, the protruding sections 7 of the legs protrude from the inclined guide surface 531, and the length of the protruding sections 7 is suitable for the flattening piece 54 to flatten the legs 4.

In the embodiment, the length of the protruding stitch 4 is not less than 2.0mm, the length of the protruding section 7 is reserved so that the pressing part 54 contacts the stitch 4 and presses the stitch 4 upwards, and since the pressing operation is performed only by bending the stitch 4 of 2.0mm, the binding space is effectively increased, compared with the traditional flat-stitch stapler 3 in which the pressing operation is performed by bending the stitch 4 of at least 3.0mm, if the length of the stitch 4 and the curved stitch part of the stitch 4 of the conventional flat-stitch stapler is 6mm, the pressing operation can be performed only by bending the stitch 4 of 3.0mm, so that the maximum thickness of the bound object is 3mm, and the breaking-through is difficult, the flat-stitch electric stapler presses the free end of the stitch 4 through the pressing part 54, the pressing operation can be performed only by bending the stitch 4 of 2.0mm, the maximum thickness of the bound object can reach 4mm, and the limitation of the binding space is broken through. Therefore, the stitch 4 is flattened in a mode that the nail groove piece 53 and the flattening piece 54 in the flat needle mechanism assembly move relatively, the nail groove piece 53 with the nail groove 530 is fixed, a working plane formed on the nail groove piece 53 is kept stable, the phenomenon of nail deviation of a bound object on the working plane in the binding process is effectively prevented, the flat needle stapler is compact in structure and simple to operate, the use efficiency is greatly improved, the use cost is reduced, and the binding thickness of the flat needle stapler under the same specification is enlarged. Meanwhile, the requirement on the length to be bent of the stitch 4 by the flattening piece 54 is lower, so that thicker bound objects can be bound conveniently, and the binding space is increased.
