斜め切断具に関する発明である。BACKGROUND OF THE INVENTION Wiring ducts made of vinyl chloride resin are often used for indoor wiring. This wiring duct is usually supplied as a long, straight object, and is cut to a required length at a construction site before use. When the wiring duct is constructed, it is necessary to bend and wire as shown in FIG. In order to construct the wiring duct in a bent state, linear members of a predetermined size are arranged to face each other, and the cut end thereof needs to be cut, for example, at an angle of 45 degrees. The present invention relates to an oblique cutting tool that can cut a long object such as a wiring duct for indoor wiring so that a cut end thereof is inclined at a certain angle with respect to an axial direction.

Description of the Related Art Conventionally, in order to cut a long object such as a wiring duct obliquely with respect to an axial direction, a saw or scissors-type cutting tool is used to determine an angle based on a scale, and to cut an object to be cut. It is common to cut while supporting with hand. For the scissors-type cutting tool, a special cutting tool in which a backing plate is fixed at an oblique constant angle with respect to the blade body is also devised.

There were drawbacks. In addition, a dedicated cutting tool to which the backing plate is fixed can cut only in a diagonal direction at a certain angle, so that it is necessary to use a plurality of cutting tools, for example, a plurality of types of cutting tools for at least 45 degrees and 90 degrees.

It is also possible to cut the object to be cut. Further, the guide means formed on the support bases on both the left and right sides are preferably formed so that the support points of the abutment plates move on an arc locus centered on the base end of the cutting blade where the attached abutment plates intersect. preferable.

In this case, however, the intersection of the contact plate 4 and the cutting blade 2a moves largely back and forth, and the cutting edge A situation arises in which the object to be cut must be cut at the part. However, in the present invention, since the left and right sides of the backing plate 4 are rotated along the guide means, it is possible to prevent the intersection position with the cutting blade 2a from largely changing. In particular, the guide means formed on the support bases 3 on the left and right sides is formed such that the support point of the contact plate moves on an arc trajectory centered on the base end of the cutting blade where the contact plate intersects. The backing plate 4 always intersects at the same position of the base end of the cutting blade 2a, and stably maintains a state in which an object to be cut in contact with the backing plate 2a can be reliably cut with a small force. Will be able to do that.

FIG. 1 is a plan view of an oblique cutting tool according to the present invention, and FIG. 2 is a side view. The main body of the oblique cutting tool is configured such that the receiving blade 1 and the cutting blade 2 are pivotally supported by a center screw 7, and the receiving blade 1 a and the cutting blade 2 a are provided on the front side, and the receiving blade 1 a and the cutting blade are used as the gripping portions 1 b and 2 b. The object to be cut can be cut at 2a. A spring 8 is mounted on the grip portions 1b and 2b to urge the blade body in the opening direction. As shown in FIG. 3, this cutting tool has a wide receiving blade 1a and presses the cutting blade 2a against a plane at the upper end of the receiving blade to cut an object to be cut. In order to make the upper end of the receiving blade a wide plane, a separate receiving table 1c is mounted as a part of the receiving blade 1a.

The height is substantially the same as the height of the upper end surface of the receiving blade 1a so that the workpiece can be stably placed. The support base 3 may be mounted on the receiving blade separately on the left and right, or in the case of cutting an object to be cut by the intersection of the receiving blade and the cutting blade like ordinary scissors, the passage space of the cutting blade is increased. Attach the support stand separately. For example, a support table in which a groove larger than the thickness of the receiving blade is formed by bending is fixed from the outer surface side that does not intersect with the cutting blade of the receiving blade.

のが好ましい。As shown in FIG. 3, the support base 3 is provided with a gate-shaped backing plate 4 having a relatively large notch so that the cutting blade 2a can be opened and closed. It is attached to straddle. The abutment plate 4 is positioned upright at a right angle to the support plate 3, and is positioned by bringing an object to be cut into contact with the front surface thereof. In the illustrated example, seats 4a, which are bent L-shaped rearward on both left and right sides,
4b is formed, and guide screws 10 and 11 are mounted thereon to serve as support points for the caul plate 4. By providing the seats 4a and 4b, the backing plate can be provided upright at right angles to the support base 3. Therefore, it is preferable to make the seats 4a and 4b large to some extent.

The support point of the guide screw 10 rotates along the guide hole 5, and the support point of the guide screw 11 rotates freely along the guide hole 6,
In addition, it can be fixed at an arbitrary rotation position.
That is, the right and left sides of the backing plate 4 are rotated along the guide holes 5 and 6 formed in the support base 3 so that the intersection angle with the cutting blade 2a can be changed. And the backing plate 4
To fix at the arbitrary rotation position, one guide screw
It is preferable that 11 is in a floating state and the other guide screw 10 can be tightened.

物の切断に支障を生じるようなことはない。In the embodiment of the pedestal 3 shown in FIG. 4, the area of the left pedestal on the drawing is made small and the area of the right pedestal is made large. Then, on each side right and left支受table 3, we are bored circular path of the guide holes 5, 6 around the O 1. Therefore, caul 4 becomes rotatable around the O 1. Center O 1 of FIG. 4, since the is positioned on the straight line connecting the guide screw 10 and the guide screw 11 of the patch plate 4, the rotation operation is smooth. In this case, the contact surface of the object to be cut is centered
Since not passing through O 1, the intersection of the contact surface and the cutting edge 2a of the object to be cut is, it will vary somewhat by the rotation angle. However, this change is slight and practically does not hinder the cutting of the object to be cut.

In this case, the backing plate 4 always intersects at the same position of the base end of the cutting blade 2a, and the object to be brought into contact with the same is always set at the base end of the cutting blade 2a. The stable sharpness can be maintained. In the drawing of FIG. 5, an angle scale 12 indicating an intersection angle between the backing plate 4 and the cutting blade 2a is described on the right side of the support base.

Since both 10 and 11 need to move along the guide holes, fixing one of them can fix the rotation of the contact plate 4. However, strictly speaking, there is a possibility that the clearance between the guide screw and the guide hole causes the rattle to be somewhat loose and the angle is not constant. Therefore, the position of the inclination angle which is generally used for each of the guide holes 5 and 6 is 90 degrees and 45 degrees in the illustrated example.
The swelling portions 5a and 6a are provided at positions corresponding to the degrees, and the abutment plate 4 is horizontally moved at the rotation position, and one of the guide screws 11 and 12 is engaged with the swelling portion. By tightening 10, the backing plate 4 is fixed at an accurate inclination angle without play.

囲内で被切断物切断することができる。According to the oblique cutting tool according to the first aspect of the present invention, only by rotating and fixing the contact plate provided on the support table attached to the receiving blade, the corresponding plate is cut. By cutting the object in contact with the object, the cut end can be cut at an accurate angle in an oblique direction at an arbitrary constant angle. Since the left and right sides of the backing plate move along the guide holes, the intersection of the backing plate and the cutting blade can be positioned near the base end of the cutting blade, and comfortable cutting can always be performed. The object can be cut within the range.

In addition to being able to intersect at the same position of the base end of the cutting blade, whatever the angle of the oblique cutting angle, the stable cutting operation can be maintained with a smaller force.
