  Next, effects of the cutting tool 3 and the cutting system 30 having the above-described configuration will be described. In order to cut the material to be cut 100, that is, the base body 1 or the cover body 2 to a predetermined length using the cutting tool 3, first, the material to be cut 100 is applied to the inner surface support portion 7 of the support 5. Place (see FIG. 3). Here, the auxiliary support member 8b is located at the first rotation position facing the inner surface support portion 7 side. The material to be cut 100 includes a base body 1 and a cover body 2. The base body 1 and the cover body 2 are assembled with each other to form a protective cover. In this assembly, the engaging piece that becomes the hooked piece 101 is engaged with the engaged portion 501. . And in embodiment of illustration, in order to cut | disconnect both the base body 1 and the cover body 2 simultaneously, these base bodies 1 and the cover body 2 were piled up (in detail, the upper and lower sides were reversed. In a state in which the cover body 2 is accommodated in the base body 1, the base body 1 is placed on the inner surface support portion 7.

  Therefore, as shown in FIGS. 4 and 5, the blade body 6 is rotated to the support body 5 side by rotating the operation handle 10, that is, by operating the operation handle 10, so that these base bodies 1 and The cover body 2 is cut. At this time, the cover body 2 is pressed by the blade body 6 and tries to rotate along the surface of the inner surface support portion 7 so as to escape from the blade body 6, but the hooked piece 101 formed on the cover body 2. However, it is latched by the latching | locking part 5a provided in the support body 5, and rotation of the cover body 2 is controlled. Thus, by restricting the rotation of the cover body 2, the cover body 2 is stably supported, and the cover body 2 can be cut smoothly.

  And since the latching | locking part 5a is provided in the side with the rotational axis 200 of the blade body 6 in the inner surface support part 7, the cover body 2 is pressed by the blade body 6, and from the blade body 6 When it tries to rotate along the surface of the inner surface support portion 7 so as to escape, a tensile stress is generated between the pressing portion of the cover body 2 and the hooked piece 101 hooked on the hooking portion 5a. For this reason, during this time, no buckling occurs when compressive stress occurs, and deformation of the cover body 2 is suppressed. Furthermore, by providing the recess 7 a in the inner surface support portion 7, it is possible to prevent the ridges 102 formed in the cover body 2 from being crushed by the inner surface support portion 7.

  In addition to the inner surface support portion 7 that supports the inner surface of the material to be cut 100, the support 5 supports the outer surface of the side portion of the material to be cut 100 and the outer surface support portion that can adjust the distance from the inner surface support portion 7. 8 is provided, the workpiece 100 having various sizes can be stably supported by the support body 5 by adjusting the interval. In other words, the cutting tool 3 can correspond to a material 100 having a relatively small size (see FIGS. 3 to 5) because the auxiliary support member 8b is positioned at the first rotation position (see FIGS. 3 to 5). Since the support member 8b is positioned at the second rotation position, it is possible to correspond to the material 100 having a relatively large size (see FIG. 6).

  In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, when cutting the wiring / piping material protective cover using the cutting tool 3, the base body 1 and the cover body 2 are cut separately by overlapping the base body 1 and the cover body 2 without cutting simultaneously. May be. In the illustrated embodiment, the hooked piece 101 is provided in the cover body 2, but when the base body 1 is provided, the hooked piece 101 provided in the base body 1 is hooked. The hook 5a of the cutting tool 3 may be formed. Further, the protective cover may not be composed of the base body 1 and the cover body 2 but may be composed only of the cover body.

  Moreover, although the latching | locking part 5a is provided in the side with the rotational axis 200 of the blade body 6 in the inner surface support part 7, according to the position of the to-be-latched piece 101, the other of the inner surface support part 7 is provided. Or the outer surface support portions 8 and 9 may be provided.

Moreover, although the outer surface support part 8 is comprised by the fixed support part 8a and the auxiliary | assistant support member 8b, the space | interval with the inner surface support part 7 is adjusted , For example, the outer surface support part 8 is as follows. By sliding relative to the base portion 5b or the main body 11, the distance from the inner surface support portion 7 may be adjusted. However, although this is a reference example, this adjustment mechanism is not necessary and may be omitted .

  Moreover, although the rotation means 300 is provided with the ratchet mechanism 310, it may be provided with another booster mechanism, and without providing these mechanisms, the operation handle 10 is simply the blade body. 6 may be directly connected.
