More specifically, the blade 60 is attached to the fixed arm 81 by screwing the bolt 63 passed through the through hole 810 formed in the fixed arm 81 into the bolt hole 62 formed in the blade 60. There is. Further, the blade 60 is attached to the movable arm 82 by screwing a bolt 63 passed through the through hole 820 formed in the movable arm 82 into the bolt hole 62 formed in the blade 60. Thus, the tool body 7 holds the cutting blade 6. The movable arm 82 is displaceable in the direction indicated by the arrow A1 in FIG. That is, the movable arm 82 can be displaced to approach or leave the fixed arm 81 along a plane orthogonal to the thickness direction of the blade 60.

  As shown in FIG. 2, the cover main body 3 is attached to the tool main body 7. More specifically, the cover main body 3 includes the fixed arm 81, the movable arm 82, a portion of the housing 74 around the fixed arm 81 and the movable arm 82, and the cutting blade 6 (a pair of blades 60). It is attached to the tool main body 7 so that it may be covered by the covering part 4 through (refer to FIG. 3). Here, that the covering part 4 covers the cutting blade 6 does not have to cover the cutting blade 6 from all directions, and it may cover from a part of the direction.

  A recess 414 (see FIG. 3) is formed on the inner surface of the cover main body 3 in the vicinity of the insertion hole 430. More specifically, the recess 414 is formed in the first wall portion 41. The tool main body 7 is formed with a convex portion 744 to be inserted into the concave portion 414 of the cover main body 3. The operator can attach the cover main body 3 to the tool main body 7 by inserting the convex portion 744 of the tool main body 7 into the concave portion 414 of the cover main body 3. In addition, the operator can remove the cover main body 3 from the tool main body 7 by removing the convex portion 744 of the tool main body 7 from the concave portion 414 of the cover main body 3.

  The covering portion 4 of the cover main body 3 protects the cutting blade 6 by covering the cutting blade 6. When the cutting tool 1 is stored, it is preferable that the cover main body 3 be attached to the tool main body 7 in order to protect the cutting blade 6.

  When the cover main body 3 is attached to the tool main body 7, the opening 410 is not blocked by the tool main body 7. The cover main body 3 is attached to the tool main body 7 so that the cutting blade 6 (a pair of blades 60) is positioned between the box-like portion 5 and the opening portion 410. In addition, the cover main body 3 is attached to the tool main body 7 so that the region of the covering portion 4 in which the opening 410 is formed faces the cutting blade 6. In more detail, the area | region in which the opening part 410 is formed among the coating | coated parts 4 opposes the cutting blade 6 in the thickness direction of the cutting blade 6 (a pair of blade 60).

  In addition, the box-like portion 5 has an opening 50 in a region on the cutting blade 6 side when the cover main body 3 is attached to the tool main body 7.

  The cover main body 3 is attached to the tool main body 7 so as to surround the cutting blade 6 together with the tool main body 7. More specifically, the side wall 43 and the tool body 7 surround the cutting blade 6. That is, each direction (front and back direction in FIG. 2) along the surface where the cutting blade 6 cuts the long portion 9 (that is, the surface orthogonal to the thickness direction of the cutting blade 6: surface orthogonal to the vertical direction in FIG. 2) The side wall 43 and the tool body 7 cover the cutting blade 6 from the left and right direction and the like. In other words, when the cover main body 3 is attached to the tool main body 7, as seen from the direction orthogonal to the plane where the cutting blade 6 cuts the long part 9, the cutting blade 6 has the side wall portion 43 and the tool main body 7. It is surrounded by

  Since the cover body 3 is entirely transparent, the entire cover body 3 corresponds to a transparent portion. The cover main body 3 is attached to the tool main body 7 so that the transparent portion faces the cutting blade 6. In particular, the transparent portion faces the cutting blade 6 in the direction along the plane where the cutting blade 6 cuts the long portion 9.

(Operation of cutting tool)
Hereinafter, with reference to FIGS. 2 and 4, an operation of the cutting tool 1 in the case where the long portion 9 is cut by the cutting blade 6 in a state where the cover main body 3 is attached to the tool main body 7 will be described. Below, the case where the elongate part 9 is a suspension bolt currently fixed to the ceiling, and the end of the elongate part 9 is facing the floor side (down) is demonstrated.

  First, the long portion 9 is passed through the opening 410 from the outside of the cover main body 3 toward the cutting blade 6. Thereby, one end of the elongated portion 9 is disposed inside the cover main body 3.

  The movable arm 82 is separated from the fixed arm 81 when viewed from the opening 410 side. At this time, the long portion 9 is disposed in the space between the pair of blades 60.

  When the trigger switch 73 is pressed, the motor housed in the housing 74 is driven, whereby the movable arm 82 is displaced in a substantially right direction (direction indicated by arrow A1 in FIG. 4) of the sheet of FIG. As the movable arm 82 is displaced, the blade 60 attached to the movable arm 82 is displaced, and the blade 61 of the blade 60 is attached to the blade 61 of the blade 60 attached to the fixed arm 81. Sandwich the long portion 9 between them to generate a shearing force on the long portion 9. Thus, the cutting blade 6 (a pair of blades 60) cuts the long portion 9 in a plane intersecting the longitudinal direction of the long portion 9. In short, the pair of blades 60 shears the long portion 9 across the long portion 9 from both sides in the sandwiching direction (the same direction as the arrow A1). In the present embodiment, the cutting blade 6 cuts the long portion 9 in a plane orthogonal to the longitudinal direction of the long portion 9.

  When the long portion 9 is cut and divided into two, the lower end portion (fragment 91) of the long portion 9 divided into two drops into the inside of the box-like portion 5. In FIG. 2, two fragments 91 of the cut long part 9 are illustrated. As described above, when the cutting tool 1 is used, the worker can easily recover the fragments 91 by the cover main body 3. In particular, by holding the handle 71 with one hand and pressing the trigger switch 73, the operator can cut the long portion 9 using only one hand and recover the fragment 91.

  Further, even when the long portion 9 is cut by the cutting blade 6, even if the fragments 91 of the long portion 9 are scattered without falling vertically, the covering portion 4 covers the cutting blade 6, so the fragments 91 are The possibility of scattering to the outside of the cover main body 3 is reduced.

  When cutting the long part 9 with the cutting blade 6, the operator looks at the long part 9 and the cutting blade 6 inside the cover main body 3 through the transparent cover main body 3, and the long part 9 and the cutting blade 6 It can be aligned with the Further, since the box-like portion 5 of the cover main body 3 is also transparent, the operator can view one or more pieces 91 of the long portion 9 in the box-like portion 5.

  In the above, the case where the long part 9 is fixed to the ceiling and one end of the long part 9 faces the floor side (down) has been described, but the direction of the long part 9 is any direction It may be. For example, even when the long part 9 is fixed to a wall or the like and one end of the long part 9 faces in the horizontal direction, the long part 9 can be cut by the cutting blade 6. Moreover, the long part 9 may not be fixed.

  As described above, the cutting tool 1 is highly convenient in that the long portion 9 can be cut by the cutting blade 6 even when the cover main body 3 is attached to the tool main body 7. The long portion 9 can also be cut with the cutting blade 6 in a state where the cover main body 3 is not attached to the tool main body 7.

  By the way, when the movable arm 82 is displaced and the pair of blades 60 of the cutting blade 6 sandwich the long portion 9, at least one of the long portion 9 and the cover main body 3 displaces the movable arm 82 ( Clamping direction: may be displaced in the same direction as the arrow A1). As a result, the long portion 9 may be displaced relative to the cover main body 3 in the sandwiching direction. For example, when the elongated portion 9 is fixed, the cover main body 3 is displaced in the pinching direction together with the tool main body 7.

  Therefore, as shown in FIG. 4, the opening 410 formed in the cover 4 has an opening width in a direction along the sandwiching direction (the same direction as the arrow A1) when the cover main body 3 is attached to the tool main body 7. L1 is larger than the opening width L2 in the direction orthogonal to the direction. In other words, when the cover main body 3 is attached to the tool main body 7, the opening 410 is formed such that the longitudinal direction of the opening 410 is along the sandwiching direction. Furthermore, the opening width L1 is larger than the distance L3 between the pair of blade portions 61 when the movable arm 82 and the fixed arm 81 are positioned apart from each other. Thereby, even if the movable arm 82 is displaced and the pair of blades 60 sandwich the long portion 9 from both sides in the sandwiching direction, the long portion 9 and the portion around the opening portion 410 in the cover main body 3 do not easily contact . The opening width L1 may be equal to or larger than the distance between the pair of blade portions 61 when the distance between the movable arm 82 and the fixed arm 81 is maximum.

(Modification of the embodiment)
Next, modifications of the embodiment will be listed. The following modifications may be implemented in combination as appropriate.

  In the cover main body 3, the open area through which the long portion 9 passes is not limited to the opening 410. The open area may not be surrounded by a member such as the first wall 41 or the like. For example, the open area may be formed in a notch by extending the opening 410 (open area) of the cover main body 3 of the embodiment to the first long side 412. Moreover, the open area may be formed in the whole of the area in which the first wall portion 41 is disposed in the cover main body 3 of the embodiment.

  Further, the open area is not limited to being formed in the first wall portion 41. For example, the open area may be formed in the side wall 43.

  Also, the open area is not limited to being formed in the covering portion 4. For example, the open area may be formed in the box-like portion 5 or may be formed across the covering portion 4 and the box-like portion 5.

  Moreover, the area | region in which the open area | region (opening part 410) is formed among the coating | coated parts 4 does not need to be opposite to the box-like part 5. FIG.

  Also, the box-like portion 5 may not protrude from the second wall portion 42, but may protrude from the side wall portion 43.

  Moreover, the box-like part 5 may be attachable to and detachable from the covering part 4.

  Further, the cover main body 3 may have a configuration in which the dimensions of the box-like portion 5 can be changed. For example, a plurality of box-like parts 5 having different dimensions may be removable from the covering part 4. The worker may properly use the plurality of box-like parts 5 having different dimensions according to the length (the length of the fragment 91) for cutting the long part 9.

  Further, the configuration of the cutting tool 1 is not limited to the configuration in which the long portion 9 is sheared by sandwiching the long portion 9 with the pair of blades 60 of the cutting blade 6. For example, the configuration of the cutting tool 1 cuts the long portion 9 by causing a cutting blade (not limited to the shape of the cutting blade 6 according to the embodiment) in contact with the long portion 9 The configuration may be The cutting blade may be, for example, a saw (including a circular saw).

  Moreover, the cover main body 3 does not need to be formed transparently. However, it is preferable that at least one part of the part which opposes the cutting blade 6 when the cover main body 3 is attached to the tool main body 7 is transparent. In particular, it is preferable that at least a part of a portion of the cover main body 3 opposed to the cutting blade 6 in the direction along the surface where the cutting blade 6 cuts the long portion 9 is transparent. Moreover, it is also preferable that at least one part of the box-like part 5 is transparent.

  Further, the cover main body 3 may not surround the cutting blade 6 together with the tool main body 7. The cover body 3 may cover the cutting blade 6 from a part of the direction. For example, the cover main body 3 may be configured to include at least the box-like portion 5 and a flat covering portion which is connected to the box-like portion 5 and covers the cutting blade 6 from one direction.

  In addition, the cutting tool 1 may be supplied with power from an external power source such as a commercial power source instead of a battery. When a battery is used as a power source, the battery may be a primary battery or a secondary battery. Moreover, although the cutting tool 1 of this embodiment is an electric tool driven by electric power, the cutting tool 1 is not limited to an electric tool. The cutting tool 1 may be, for example, a pneumatic tool driven by compressed air supplied from a pneumatic pump using a pneumatic pump as a power source, or driven by hydraulic pressure supplied from a hydraulic source using a hydraulic pump as a power source. It may be a hydraulic tool.

(Summary)
As described above, the cutting tool cover 2 according to the first aspect includes the cover main body 3. The cover main body 3 is attached to a tool main body 7 that holds the cutting blade 6.
