[Embodiment of device]

    (First Embodiment of the Invention)   A cutting tool according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 7. Reveal 1 is a front view of a cutting tool according to the present embodiment, and FIG. 2 is a cutting view according to the present embodiment. 3 is a plan view of the cutting tool according to the present embodiment, FIG. 3 is a front view of the cutting tool according to the present embodiment, and FIG. FIG. 5 is a bottom view of the cutting tool, FIG. 5 is an exploded view of a main part of the cutting tool according to the present embodiment, and FIG. Of operation of the cutting tool according to the embodiment, FIG. 7 shows an operation of the cutting tool according to the present embodiment. You

[0009]   In each of the above drawings, the cutting tool according to the present embodiment has a blade 11 for cutting into an object to be cut. Blade portion 1, a handle portion 2 formed on the base end 13 side of the blade portion 1, and a tip 12 of the blade portion 1. And a support portion 3 for rotatably supporting the blade and an insertion groove for fixing the support portion 3 to receive the blade portion 1. 41 and a base 4 on which a blade receiving portion 41 is formed. It is a configuration in which the shape of the blade 11 is formed by being raised in a curved shape from the lower end surface of the support portion 3. .

[0010]   The blade portion 1 includes a blade 11, a tip 12 and a base end 13 as shown in FIG. As described above, the blade 11 in the direction of the tip 12 bulges in a curved shape and is rotated by the support portion 3. A round hole 14 (see FIG. 5 (b)) is formed in the distal end 12 to be fixed at the base end. 13 is the formation covered with the handle 2. However, the base end 13 is covered by the handle portion 2. Alternatively, the base end 13 may be exposed and the base end 13 itself may form the handle 2.

[0011]   A metal plate 42 made of stainless steel is provided on the base 4, and the base 4 is not inserted. Pores 43 are formed corresponding to the through grooves 41. In this way, insert the course into the base 4 41 Is formed, the pores 43 are formed in the metal plate 42, and the blade portion is formed even when the handle portion 2 is lowered. The blade 11 of 1 does not come into contact with the base 4 or the metal plate 42, etc. No blade spillage.

[0012]   The support portion 3 is rounded in the lateral direction in order to rotatably fix the tip 12 of the sword portion 1. A hole 31 is formed, and the round hole 31 and the round hole 14 of the sword portion 1 are aligned with each other to bolt. 32 is inserted and the tip of the bolt 32 is tightened with the nut 33 so that the tip 12 is Will be supported.

[0013]   Next, the operation of the cutting tool according to the present embodiment will be described. Lift the handle 2 The rotation of the tip 12 of the blade 1 causes a large gap between the metal plate 42 and the blade 11. . For example, an elliptical object to be cut is inserted into this gap, and the lifted handle 2 is lowered. . By lowering the gap, the gap becomes smaller, and the curved portion of the blade 11 of the blade portion 1 becomes a pair to be cut. Contact an elephant. The tip of the blade 11 is formed in a curved shape, and the external force generated on the object to be cut first It works in the direction of the end 12 and does not work in the direction of the base 13 at all, securely fixing the object to be cut. Since there is no movement, even if there is movement, it moves toward the tip 12 and It is surrounded by the blade 11 and the metal plate 42 and eventually fixed, so external force is efficient. It can be easily transmitted to the object to be cut. Also, the movement trajectory of the blade 11 Since the tip 12 of the blade part 1 is fixed on the support part 3, it is restricted to a predetermined trajectory. It is safe because

[0014]   Whether or not an external force in the direction of the base end 13 acts on the object to be cut is determined from the lowest point of the blade 11 to the tip 1. It depends on whether or not the object to be cut contacts the blade 11 on the second side (left side in the drawing). Blade 11 When touches the object to be cut at the lowest point, external force is applied to the object to be cut vertically downward. (Fig. 6 (a) showing the state when they come into contact with each other), The external force applied to the object to be cut by the blade 11 by rotating the tip 12 is also a component in the tip 12 direction. Is large (Fig. 6 (b) showing the state when the blade 11 enters the object to be cut). It is possible to appropriately cut the object to be cut without escaping. See Figure 6 Then, in FIG. 6B, the force of the horizontal component toward the tip 12 is larger than that in FIG. 6A. You can see that it is getting bigger. Here, the horizontal arrow in the figure is the horizontal component. , And the vertical arrow indicates the force of the vertical component.

[0015]   If the blade 11 contacts the object to be cut on the tip 12 side from the lowest point, The force acts on the tip 12 direction component, and the tip 12 direction component becomes large after that, so the cutting target The object can be cut appropriately without escaping (see Fig. 7. (B) shows the state when the blade 11 has entered the object to be cut). Figure 7, in comparison with FIG. 7 (a), FIG. 7 (b) shows a horizontal direction toward the tip 12 direction. You can see that the power of the minute is increasing.

[0016]   When the blade 11 contacts the object to be cut on the base end 13 side (right side in the drawing) from the lowest point Means that the external force acts on the base end 13 direction component at the time of contact, and thereafter the base end 13 direction component is large. Therefore, the object to be cut escapes and cannot be cut properly. However The above description assumes that friction does not work on the metal plate 42. According to Since the object to be cut is placed on the metal plate 42, a drag force is generated vertically upward. If friction occurs on the metal plate 42, a small force of the base end 13 direction component acts. Even if it does, it does not move because there is a static friction force obtained from the drag force and the friction coefficient, and cutting This will have no particular effect on. The friction coefficient here is determined only by the metal plate 42. If there is seawater on the object to be cut, the metal plate 42, or the metal plate 42 In this case, factors such as seawater are taken into consideration.   In addition, when the blade 11 enters the object to be cut, the wear that acts between the blade 11 and the object to be cut. Whether the rubbing force and the cutting condition of the blade 11 move the object to be cut in the direction of the base end 13 Get involved.

[0017]   As described above, according to the cutting tool of the present embodiment, the portion of the blade 11 in the tip 12 direction is cut into a groove. Since it is raised in a curved shape, the cut object placed in the gap created by lifting the handle 2 By lowering the handle 2 onto the target, the curved portion of the blade 11 first comes into contact, and thereafter the support 3 is moved. The blade 11 rotates around the center, and an external force of the blade 11 on the object to be cut is generated in the direction of the tip 12. Since it does not occur in the direction of the base end 13, the object to be cut does not move to the base end 13 side and is reliable. Can be cut into

[0018]   In addition, in the cutting tool according to the present embodiment, a protrusion for fixing an object to be cut such as a pick. It is also possible to form the stopper 44, which is a product, on the metal plate 42 so that the object to be cut is moved. It can be cut smoothly without moving. Specifically, as shown in FIG. A nail-shaped stopper 44 is provided on the metal plate 42 to pierce and fix the object to be cut. As shown in FIG. 8B, a plurality of barb-shaped stoppers 44 are provided on the metal plate 42, and It is also possible to make the cutting target difficult to move.

[0019]   In addition, in the cutting tool according to the present embodiment, a protrusion for fixing the object to be cut such as a pick. It is also possible to form a protrusion on the metal plate 42 with the projection directed toward the tip 12, and When the elephant is placed, the protrusions do not interfere, and when cutting the If a force is generated, the protrusion will generate a large drag force and the object to be cut will not move. It can be cut smoothly. Specifically, as shown in FIG. ) Is an enlarged view of the main part of the dotted circular part in (a)), and there are multiple protrusions facing the tip 12 direction. By providing the barb-like stopper 44 on the metal plate 42, the tip 1 can be moved from the base end 13 direction. It can be easily done when inserting the object to be cut in two directions and placing it, and when actually cutting The protrusion of the stopper 44 makes it difficult for the object to be cut to move, so that the cutting can be performed smoothly. You can

[0020]

[Effect of device]

  As described above, in the present invention, the shape of the blade portion near the tip of the blade is changed to the shape below the support portion. Since it is formed by bulging in a curved shape from the end surface, it is possible to cut the object to be cut before the lowest point of the blade. The blade on the end side contacts the object to be cut and applies shearing force in the tip direction to cut it. The object to be cut can be reliably cut without moving in a direction that hinders cutting. By the lever principle, the force applied to the force point is smoothly supported by the supporting part as a fulcrum The effect is that it is easy to cut and can be cut easily.

[0021]   Further, in the present invention, since the stopper is provided near the blade receiving portion, It moves even if an external force in the horizontal direction occurs on the object to be cut sandwiched between the blade receiving part and the blade. Even if the blade on the proximal side from the lowest point of the blade contacts the object to be cut without being fixed There is an effect that the object to be cut can be surely cut.

[0022]   Further, in the present invention, the protrusion of the stopper protrudes toward the tip of the blade. Therefore, when placing the object to be cut in the direction from the base end of the blade to the tip, It can be easily placed without the projection of the blade becoming an obstacle, and the stopper is cut when cutting. The object can be fixed and cut reliably, and after cutting, the object to be cut is cut into two This has an effect that the object to be cut can be easily taken out.
