Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is intended for cutting various tapes, strings, fishing guts, etc. It relates to a nail clipper type cutter used.

[Conventional technology and its problems]

When cutting various wound products in the rolled state by the general user, cutting tools such as scissors and knife type cutters are usually required, and it often takes time to find these cutting tools. Also, there is a problem that the cutting operation is troublesome.

On the other hand, in some tapes using a base material such as cellophane or paper which is easily broken, a holder for accommodating them in a wound state is provided with a saw blade-shaped or edge-shaped cutter portion. However, with such a cutter part, it is not possible to cut tapes that use a strong base material such as polyester film, wrapping straps, packing straps, fishing guts, etc. Since the tape is cut into pieces, the tape ends are not sharp and the appearance is poor.

[Means for solving the problem]

In view of the above situation, the present invention can easily and accurately cut various strips fed from the wound state,
(EN) Provided is a cutter having a sharp cutting end, which can be easily attached to a holder or the like for accommodating a wound product of these strips.

That is, the first aspect of the present invention is that a pair of upper and lower metal strips, each of which has a pair of blade portions facing each other at their front ends and whose rear end portions are joined so that both blade portions are normally open, and an upper strip thereof. A pressing lever made of metal, the front end of which abuts on the plate and which is inclined. The front end of the pressing lever is pivotally connected to a pair of bearing pieces projecting upward on both sides of the front end of the lower strip. In addition, a pressing portion that contacts the upper strip is provided near the rear of this pivotal portion, while a strip introducing port is opened in the middle of the lower strip, and the upper strip is pushed toward the lower strip by pressing the pressing lever. The present invention relates to a strip cutting cutter that is pressed against a blade and is configured such that the two blade portions mesh with each other.

A second aspect of the present invention is that the above cutter has a strip feed guide extending from the strip inlet to the vicinity of both blades.

[Action]

The strip fed from the wound state is guided between the strips through the strip introduction port of the lower strip, and is led outside between the blades of the cutter. Then, by pushing out the pressing lever after drawing it out to a predetermined length, the lever is rotated around the front end pivotal portion so that the rear end (free end) approaches the upper strip. Along with this, the front end side of the upper strip plate is elastically deformed so as to be pressed to the lower strip plate side by the pressing portion, and both blade portions mesh with each other to sharply cut the strip body. This is the same operation as cutting a nail with a so-called nail clipper.

However, in a normal nail clipper, the pressing lever is pivotally attached at the center of the front end portion to one protruding shaft that projects from the lower strip plate and penetrates the upper strip plate. In order to insert the strip, the pressing levers are pivotally connected to the pair of bearing pieces protruding upward on both sides of the front end of the lower strip, and the strip introduction ports are provided on the lower strip. There is a difference in structure from the nail clipper.

The strip to be cut is not particularly limited, and various tapes, strings, fishing gowns, etc. can be mentioned, but it is strong in sending out from the above-mentioned strip introduction port through the blade parts. Those are preferable.

It should be noted that this cutter may be attached to the strip feeding portion of various holders for holding these strips in a wound state. Further, by providing a strip feeding guide from the strip introducing port to the vicinity of both blades, the strip feeding is stabilized.
