Description

[Detailed description of the invention] [Industrial application field] The invention provides a method for loading staples into a magazine.
Concerning effective stapling.

[Prior Art] As this type of stapler, the following are conventionally known.

For example, it is composed of a base, a magazine, and a handle, and each distal end is provided with a clincher, a staple ejection opening, and a driver, and the handle and base and the handle and magazine are rotated on the same axis at each base end. The staples in the staple loading area formed longitudinally between the staple feeding pusher housed in the magazine and the staple ejection port are directed from the staple ejection port toward the clincher by a driver. Staples can be loaded into the magazine by punching out the staples, rotating the handle to open the handle relatively so that the tip of the handle is separated from the magazine, and retracting the staple feed pusher. Things can be mentioned.

Furthermore, there is a so-called one-touch open type in which the staple feed pusher of the magazine and the handle are connected by a link member, whereby the staple feed pusher is automatically retracted as the magazine and handle are rotated. Can be mentioned.

[Problem to be solved by the invention] By the way, regarding the above conventional stapler,
The rotational axis of the handle and base and the rotational axis of the handle and magazine are the same axis, and the base end of the magazine always interferes with the rotational axis of the base and handle. When loading staples, the backward motion of the staple feed pusher is restricted at the base end of the magazine, making it difficult to load staples, which necessitates sacrificing the staple loading area, which poses a problem.

Generally, a predetermined number of staples are loaded into a staple loading area of a magazine as a series of connected staple staples. For this reason, for magazines, the length of the staple loading area is somewhat longer than the unit length of staple staples, and even if some staples remain in the area, a new series of staples can be loaded. Preferably, the staple loading area is always filled with many staples. The longer this extra area is, the sooner a series of staple staples can be refilled.

Therefore, in such a case, it is necessary to make the magazine itself longer or to make the staple feeding pusher smaller to form a longer staple loading area. However, if the magazine itself is lengthened, the handle and base will also be lengthened, resulting in an increase in the size of the stapler. On the other hand, if the pusher is made shorter without making the magazine itself longer, measures such as reducing the compression length of the coil spring when the pusher retreats are required without reducing the force exerted during staple feeding, making the structure complicated. There was a problem.

The present invention was developed in view of the above problems, and its purpose is to prevent the rotation axes of the handle and the base and the rotation axes of the handle and the magazine from being on the same axis. , the rear end of the magazine does not interfere with the rotation axis of the base and handle, and when loading staples, the backward movement of the staple feed pusher is not restricted at the rear end of the magazine, making it easy to load staples. Then,
Therefore, the staple loading area is effectively secured within the magazine without being sacrificed, the length of the stapler main body is suppressed, and the structure can be simplified and downsized without considering the biasing force of the pusher.

[Means for Solving the Problems] In order to solve the above-mentioned conventional problems, the present invention includes a base having a clincher at its tip for bending the staple legs of the staple, and a staple driver facing the clincher. a magazine for accommodating a staple feeding pusher having an outlet at a distal end and slidably movable along the longitudinal direction and forming a staple loading area between the pusher and the staple ejection opening; a handle that is rotatably supported at the base end thereof and rotatably supported at each proximal end relative to the magazine, and has a driver at its distal end that drives out the staple from the staple exit port toward the clincher; In the stapler, the stapler can be loaded by a leg opening operation to relatively open the handle so as to separate the tip end of the handle from the magazine and a retracting operation of the staple feeding pusher. A second rotation axis of the handle and the magazine is arranged eccentrically with respect to a first rotation axis of the handle and the base, and as the handle and the magazine are rotated to open the legs, the second rotation axis The present invention proposes a stapler characterized by a structure in which the magazine is projected forward by moving the rotation axis forward from the first rotation axis.

Further, in the above configuration, the staple feeding pusher and the handle are connected by a link member,
It has been proposed that when loading staples by opening the magazine and the handle, the link member causes the staple feed pusher to move backward in a one-touch manner.

[Function] With the above configuration, in the stapler according to the present invention, the second rotation axis of the handle and the magazine is arranged eccentrically with respect to the first rotation axis of the handle and the base, and the handle and the base are arranged eccentrically. The magazine is protruded forward by moving the second rotation axis forward from the first rotation axis as the legs are rotated between the magazine and the base end of the magazine. When loading staples, there is no restriction on the backward movement of the staple feed pusher at the base end of the magazine, making it easier to load staples. The loading area is effectively secured within the magazine without being sacrificed, the length of the stapler body is suppressed, and the structure can be simplified and downsized without considering the biasing force of the pusher.
