Movable base adsorbent 1 which attracts each other by magnetic force
6, the cutting blade 14 is provided with a suction part 18 that sucks the base adsorbent 16 and the base adsorbent 16 and the suction part 18 when the soft thin material P is cut. This means that the back surface of the object to be cut is magnetically attracted to the suction part 18 from each other by the magnetic force, and the base adsorbent 16 is interlocked with the movement of the cutting edge 14a of the cutting blade 14.

In the present embodiment, as shown in FIGS. 1 to 6, the suction portion 18 is formed in a quadrangular prism shape and is fixed to one side surface near the cutting edge 14a of the cutting blade 14. The attracting portion 18 is a magnet 1 in the shape of a square pole that is a magnetic body.

The blade tip 14a is further projected. Further, as shown in FIG. 11, the attraction portion may be composed of a cylindrical magnet 19, and in this case, the attraction surface 19a is formed in a substantially circular shape.

In the present embodiment, the suction portion 18 is formed in a square column shape or a column shape.
It may be formed in a triangular column shape or a semi-cylindrical column shape.
It suffices if the cutting edge 14a of the cutting blade 14 can be moved and projected to the projecting port 22. In the present embodiment, the suction portion 18 is fixed to one side surface in the vicinity of the cutting edge 14a of the cutting blade 14, but this is, for example, the cutting edge 14a of the cutting blade 14.
May be fixed to both side surfaces in the vicinity of, and the point is that the cutting edge 14a of the cutting blade 14 can be moved and projected to the projection port 22. Further, the suction part 18 may be configured by a donut-shaped ring body or the like, and the cutting blade 14 may be provided at the center of the ring body.

In the present embodiment, the suction part 18 is formed in a quadrangular prism shape or a cylindrical shape and is fixed to one side surface in the vicinity of the cutting edge 14a of the cutting blade 14. This is, for example, the material of the cutting blade 14. By using a ferromagnetic metal piece that is subjected to a magnetic force on the cutting blade 14, the suction portion may be configured in the cutting blade 14. The point is that the cutting edge 14a of the cutting blade 14 is moved and projected to the projecting opening 22, and It is only necessary to interlock the base adsorbent 16 (described later) with the movement.

In this embodiment, the base adsorbent 16 is shown in FIG.
As shown in, the magnet or the ferromagnetic material is used as a material and is formed in a substantially rectangular shape in a plan view. Then, at least the soft layer 36 in which a film made of synthetic resin is adhered to the blade contact surface, which is a wide flat surface having a polarity different from that of the suction surface 18a, is provided. As a result, when the soft layer 36 side of the base adsorbent 16 is brought closer to the bottom wall 12c side, a suction force by magnetic force acts between the suction surface 18a of the suction unit 18 and the soft layer 36 side of the base adsorbent 16. Will be made. The attraction force of the magnetic force is stronger than the force of the spring 32 that houses the cutting blade 14 in the storage area 28. Therefore,
The cutting blade 14 provided with the suction portion 18 by magnetic attraction attracts the bottom wall 1
Move in 2c direction. Then, the cutting edge 14a has a protrusion 22
It protrudes further and enters the soft layer 36 of the base adsorbent 16. The base adsorbent 16 may be provided with a soft layer 36a on the entire surface of the magnetic body as shown in FIGS.

As shown in FIG. 11, the base adsorbent is
A circular magnet 17 having substantially the same diameter as the cylindrical attraction portion 19
In this case, the circular surface of the attraction surface 19a and the circular surface of the circular magnet 17 are attracted by mutual magnetic force,
Since the cutting edges 14a of the cutting blade 14 can be reliably positioned at a specific position of the circular magnet 17, the soft layer 3 of the circular magnet 17 can be surely positioned.
The cutting edge 14a can be thrust into the blade 7.

Further, the base adsorbent may be provided with a yoke which surrounds the magnet with a silicon steel plate or the like. , In this case, at the same time as sucking the suction part 18 more strongly,
The cutting edge 14a of the cutting blade 14 can be more reliably thrust into a specific position of the base adsorption body. Further, it is possible to prevent the base adsorbent from interfering with other ferromagnetic metal pieces by restricting the effect of the magnetic force in the unnecessary direction by acting the magnetic force only in the direction of the attraction portion.

In the present embodiment, the base adsorbent 16 is made of a magnet, but it may be made of a ferromagnetic metal piece, for example, as long as it can magnetically attract the attracting portion 18. It is good if possible. In this embodiment, the base adsorbent 16 is formed in a substantially rectangular shape in a plan view, but it may be formed in a triangular shape or a donut shape in a plan view. It is good if magnetic attraction is possible. In this embodiment, the soft layer 36 is formed by attaching a synthetic resin film to the base adsorbent 16. For example, a synthetic resin coating, leather, wood, paper, rubber or soft metal is used as the base. It may be attached to the adsorbent body 16.
It suffices that the cutting edge 14a is softer than a magnet or a ferromagnetic metal piece and that the cutting edge 14a of the cutting blade 14 can penetrate even a little.

In the present embodiment, the cutting tool 10 is provided with a guide plate 38 for guiding the cutting blade 14 when cutting the soft thin material P as shown in FIGS. The guide plate 38 is made of hard synthetic resin and is formed in a thin plate-like oblong shape. Then, a guide hole 40 for guiding the main body 12 is opened substantially at the center. Therefore, the guide plate 38
Accurately inserts the main body 12 into the guide hole 40 to guide the movement of the cutting blade 14 incorporated in the main body 12,
In addition, it is possible to perform reliable cutting.

In the present embodiment, the guide plate 38 is made of hard synthetic resin, but it may be made of soft synthetic resin or metal. In the present embodiment, the guide plate 38 is formed in a thin plate-like rectangular shape, but it may be formed in, for example, a thin plate-like circular shape or a triangular shape. It would be nice if we could guide. In the present embodiment, the guide plate 38 guides the movement of the cutting blade 14 by the guide hole 40. However, this may guide the movement of the cutting blade 14 at the end of the guide plate 38. Is only required to be able to guide the movement of the cutting blade 14. Incidentally, reference numeral 42 in the figure is a stop pin for fixing the suction portion 18 to the cutting blade 14. In the figure, L is a cutting trace showing a trace of the soft thin material P being cut by the cutting blade.

Next, the operation of the cutting tool 10 according to the embodiment will be described with reference to FIGS. 1 and 2. In FIG.
An operator who performs the cutting (hereinafter referred to as “operator”) places the base adsorbent 16 on the back surface side of the portion where the soft thin material P is cut. At this time, the soft layer 36 is brought into contact with the back surface side of the soft thin material P. Then, grasp the main body 12 by hand,
The bottom wall 12c is brought into contact with the soft thin material P so that the base adsorbent 16 is directly below. Then, the suction unit 18 and the base adsorption member 16 perform magnetic attraction, and the cutting blade 14 including the suction unit 18
Is moved to the bottom wall 12c side, and the blade edge 14a is projected from the projecting port 22. Then, the cutting edge 14 a protruding from the protruding port 22 penetrates the soft thin material P and projects into the soft layer 36.

Next, the worker, as shown in FIG.
Move 2 to the desired shape. Then, the cutting blade 14 penetrating the soft thin material P cuts the soft thin material P into a desired shape. At this time, the magnetic attraction force of the suction unit 18 acts on the base suction body 16, and the suction force causes the base suction body 16 to interlock with the cutting edge 14a. That is, the blade edge does not move on the base adsorbent 16 but always contacts the base adsorbent 16 when the soft thin material is cut.

When the guide plate 38 is used to cut a desired shape, the guide plate 38 is placed on the front side of the soft thin material P so that the base adsorbent 16 is located in the guide hole 40. The main body 12 may be inserted into the guide hole 40 and the above operation may be performed.

Therefore, when the soft thin material P is cut, the base adsorbent 16 is always in contact with the cutting edge 14a, so that the lower surface of the soft thin material P can be cut without being scratched by the cutting edge 14a, and at the same time the base can be cut. Since the suction body 16 can be interlocked with the cutting blade 14 without any restriction,
The soft thin material P can be cut into any shape or size, and accurate cutting work can be performed quickly.
Since the base adsorbent 16 and the suction portion 18 sandwich the object to be cut and magnetically attract each other, the cutting edge 14a can penetrate the object to be cut without pressing the object to be cut on a work table or the like. Therefore, for example, even when the newspaper N or the like is held in an unstable state as shown in FIG. 12, the cutting tool 10 can safely and easily cut out the newspaper N. Furthermore, since the cutting edge 14a of the cutting blade 14 is built in the main body 12 unless the suction force generated by the magnetic force acts on the suction portion 18, it is possible to prevent an injury or an accident due to an unexpected protrusion of the cutting edge.

The cutting tool 10 of the present invention may be used for a cloth attaching operation in the interior finishing of a house. That is, in the cloth tensioning work at the time of finishing the interior of the house, when cutting the cloth into a desired shape with a cutter, if the paper is too strongly cut, the paper on the surface of the underlying plasterboard may be cut with the cutter, and When the base is an iron door or steel, there is a problem that rust occurs because the rust preventive paint applied to the surface of the base is scraped off with a cutter. However, by using the cutting tool 10 of the present invention, The adsorbent 16 receives the cutting edge 14a under the cloth, so that the above-mentioned problem can be solved.

The cutting tool 10 of the present invention is not limited to the above-mentioned embodiments, but may be modified arbitrarily within a range not departing from the essence of the invention described in the claims.

Since the blade edge of pierces the object to be cut and is in contact with the same base adsorbent, the cutting blade moves and protrudes from the main body only by the magnetic attraction of the base adsorbent during cutting. It is built in and can prevent the cutting blade from moving and protruding from the main body. As a result, it is possible to prevent injuries and accidents due to the unexpected protrusion of the cutting blade and to ensure safety. When the base adsorbent is separated from the vicinity of the cutting blade, the cutting blade is instantly built into the main body,
For example, even if the cutting tool runs out of control at the time of cutting, injury or the like due to the cutting blade can be prevented, and safety when using the cutting tool can be improved.

Further, according to the cutting tool of claim 4, since at least the blade contact surface of the base adsorbent body is provided with the soft layer into which the blade tip of the cutting blade projects, the cutting blade is cut at the time of cutting. Since the object to be cut can be reliably penetrated, complete and reliable cutting can be performed.

Further, according to the cutting tool of the fifth aspect, since the attraction portion and the base adsorption body are provided with circular magnets having substantially the same diameter, the circular surfaces of the attraction portion and the foundation adsorption body are displaced from each other. Since the cutting edges are matched with each other without fail, the cutting edge of the cutting blade can be reliably positioned on the circular surface of the base adsorbent, and the cutting edge can be projected into the soft layer.
