Description

[Detailed description of the invention] The present invention relates to a pair of flat cutting scissors that improves sharpness by slightly moving one blade plate in the longitudinal direction to provide a flat cutting action, and the attached drawings are shown in the figure. For reference, the detailed configuration is as follows.

The shaft mounting hole of the upper blade plate 1 is formed into a long hole 2 to form the upper blade plate 1.
is provided so that it can slide freely.

An opposing gap 7 is formed between the sliding parts 5 and 6 of the upper blade plate 1 and the lower blade plate 3 below the shaft attachment part 4.

A connecting plate 8 is interposed within this opposing gap 7.

The upper end of this connecting plate 8 is connected to the sliding part 6 of the lower blade plate 3.
The shaft is mounted on the upper part near the shaft mounting part 4.

The lower end of the connecting plate 8 is pivoted to the lower part of the sliding part 5 of the upper blade plate 1 that is remote from the pivoting part 4.

In the figure, 9 is a mounting bolt, 10 is a nut, 11,
12 is a shaft, 13 is a locking pin, and 14 and 15 are grip handles.

Conventional scissors are cross-mounted, so both the upper and lower blade plates simply rotate about the pivot point.

In the present invention, a connecting plate 8 is interposed between the sliding parts 5 and 6, and the upper and lower scissors are connected by this connecting plate 8. Therefore, the point P in FIGS. Therefore, the trajectory will be taken with point B below the pivot point A as the fulcrum.

Of course, in order to move along this trajectory, the upper blade plate 1 cannot be rotated unless a shaft mounting hole is formed in the elongated hole 2 and the upper blade plate 1 is slidably provided.

By providing the connecting plate 8 in this manner, the upper blade plate 1 is movable in the length direction within the length range of the elongated hole 2, unlike conventional scissors, and exhibits a smooth cutting action.

Therefore, the scissors have a better cutting ability than conventional scissors.

Since this connecting plate 8 is housed in the opposing gap 7 formed between the sliding parts 5 and 6, the sliding parts 5 and 6 other than the facing gap 7 are in close contact with each other, and in the case of this embodiment, Width of opposing gap 7 and connecting plate 8
Since the thickness of the connecting plate 8 and the inner surface of the upper blade plate 1 or the lower blade plate 3 are approximately the same, there is also a close contact between the surface of the connecting plate 8 and the inner surface of the upper blade plate 1 or the lower blade plate 3, so that a facing gap 7 exists. The scissors do not interfere with the operation of the scissors in any way, and since the structure of these attachments is not that complicated, they are easy to manufacture, and these scissors exhibit excellent features that make them extremely sharp.

Furthermore, the fact that the connecting plate 8 is interposed between the upper blade plate 1 and the lower blade plate 3 means that the connecting plate 8 is not attached to the outer surface of the scissors, and the connecting plate 8 is located on the outer surface of the scissors and does not interfere with the scissors. The scissors also have the advantage of being extremely easy to use, as they do not cause any irritation.

Claims (1)

[Scope of utility model registration request] The shaft attachment hole of the upper blade plate is formed into a long hole to allow the upper blade plate to slide freely, and an opposing gap is formed at the sliding part below the shaft attachment part of the upper blade plate and the lower blade plate. A connecting plate is interposed in the opposing gap, and the upper end of the connecting plate is pivoted to the upper part of the sliding part of the lower blade plate near the pivoting part,
A pair of cutting scissors characterized in that the lower end of the connecting plate is pivoted at the lower part of the sliding part of the upper blade plate, which is away from the pivoting part.
