Embodiment Construction

[0023] The following examples illustrate possible implementations of the present invention, but are not intended to limit the protection scope of the present invention.

[0024] Please refer to Figures 1 to 10 , which shows a preferred embodiment of the present invention, the stapler 1 of the present invention includes a body 10 , a firing mechanism 20 and a narrowing mechanism 30 .

[0025] The body 10 includes an internal space 11 and a nail opening 12; the firing mechanism 20 is located in the internal space 11 and includes a striking member 21 for striking a nail 2 and a driving member 21 that can drive the striking member 21 relative to the nail. The driving member 22 for moving the mouth 12; the needle narrowing mechanism 30 is arranged on the body 10 and includes a needle groove hole 31 opposite to the nailing hole 12, at least one pusher 32 movable in the needle groove hole 31 and A power storage component 33 that can be driven by the driving member 22, the power sto...

Abstract

The invention relates to a stapler. The stapler comprises a main body, a firing mechanism and a staple retracting mechanism, wherein the main body comprises an internal space and a staple striking opening; the firing mechanism is arranged in the internal space and comprises a striking piece for striking a staple pin and a driving piece capable of driving the striking piece to move relative to the staple striking opening; the staple retracting mechanism is arranged on the main body and comprises a staple groove hole opposite to the staple striking opening, one or more pushing pieces capable of moving in the staple groove hole and a force storage assembly capable of being driven by the driving piece, the force storage assembly comprises a latching part and a force storage piece capable of being clamped and blocked with the latching part in a releasable mode, and the force storage assembly can strike the one or more pushing pieces towards the staple groove hole; when the driving piece drives the striking piece to move towards the staple striking opening, the driving piece drives the force storage assembly to deform and store force, and when the force storage piece is deformed through force storage to be separated from the latching part, the force storage assembly instantly strikes the one or more pushing pieces to move towards the direction of the staple striking opening so as to enable the striking piece to abut against the staple pin. According to the invention, the pins of a staple can be indeed flattened, and the flat stapling effect is better.

Description

technical field [0001] The present invention relates to a stapler. Background technique [0002] Generally, the stapler is fixedly provided with a nail anvil corresponding to the nail hole, and the nail anvil is provided with two recesses for pressing against the two stitches of a nail, so that the two stitches can be bent to achieve the effect of binding. However, because the two stitches are bent inwardly along the structure of the two recesses, if the operating force is improper, the binding effect will be affected, and the two stitches cannot be completely flat on a surface of a bound object, resulting in the presence of the nail. The thickness of the needle is relatively large, which is not good for aesthetics and is not conducive to document arrangement, so a stapler with a flat needle function has been developed. [0003] Known plain needle stapler, as the disclosed technical scheme of Taiwan Patent No. M496540, it comprises a body, a slide table that is movably loca...
