The first handle 10 and the second handle 20 are hinged to each other.

That is, the first handle 10 extends to the lower side of the hinge member 12 on one side.

The second handle 20 protrudes from both sides of the hinge protrusion 23 on one side.

At this time, the second handle 20 is preferably inserted into one side of the hinge member 12.

In addition, the hinge member 12 passes through the hinge hole 13.

Thus, as the hinge protrusion 23 is rotatably inserted into the hinge hole 13, the first handle 10 and the second handle 20 are hinged based on the hinge protrusion 23.

Accordingly, the first handle 10 and the second handle 20 are rotated in opposite directions with respect to the hinge protrusion 23.

In particular, the first handle 10 and the second handle 20 can be modified in a variety of shapes, it may be made of a variety of materials.

In addition, the hinge member 12 may be detachably formed on the first handle 10, but is preferably integrally formed.

Of course, the hinge member 12 may be formed in various shapes.

In addition, the structure in which the first handle 10 and the second handle 20 are hinged may be variously modified.

On the other hand, the casing 30 serves to protect the sliding blade 40, it is formed to be open to both sides so as to expose the sliding blade 40 to both sides.

The casing 30 may be integrally formed with the first handle 10 or the second handle 20, but may be detachably formed for maintenance and compatibility.

For convenience, the casing 30 is shown detachably formed on the first handle 10.

Of course, the casing 30 may be modified in various shapes and may be made of various materials.

In particular, as an example, the first handle 10 protrudes to form a coupling protrusion 15 at one side edge, and the casing 30 is formed to recess the coupling groove 35 to enable the coupling protrusion 15 to be separated therein. do.

That is, the casing 30 is coupled to the first handle 10 as the coupling groove 35 of the casing 30 is forcibly fitted to the coupling protrusion 15 of the first handle 10.

At this time, the casing 30 is separated from the first handle 10 through the separation of the coupling groove 35 from the coupling protrusion 15 as the edge is opened by the external force.

Accordingly, the casing 30 is preferably made of a size that forcibly inserts one side edge of the first handle 10.

In addition, the slidable blade 40 is formed by cutting a cutting angle and is preferably provided with a pair to be able to cut the cutting object 2, it is supported by the casing 30 and the first handle 10, respectively desirable.

Of course, the sliding blade 40 may be made of a plurality of cutting angles, it is preferably provided in a pair.

In more detail, the sliding blade 40 includes a lower blade 42 and an upper blade 44.

The lower blade 42 is detachably fixed to one side of the first handle 10.

That is, the lower blade 42 is detachably coupled to one side of the first handle 10 by various methods such as bolting.

At this time, the lower blade 42 is fixed in position even when the first handle 10 and the second handle 20 are manipulated.

In addition, the lower blade 42 forms the insertion hole 43 to insert the cutting object (2).

In particular, the insertion hole 43 is formed at the edge of the lower blade 42, is formed to open in both the up and down direction and one direction.

Thus, the cut object 2 such as a band cable can be easily inserted into the insertion hole 43.

Of course, the lower blade 42 may be deformed into various shapes and made of various materials.

In addition, the upper blade 44 is supported by the casing 30.

In this case, the reason why the upper blade 44 is not connected to the first handle 10 supporting the lower blade 42 is that the upper blade 44 and the lower blade 42 are fixed to the lower blade 42. This is to cut the cutting object 2 inserted into the lower blade 42 by advancing back and forth at a cutting angle.

That is, only one upper blade 44 and the lower blade 42 are installed to move forward and backward.

Of course, the upper blade 44 may be formed on one side of the first handle 10, and the lower blade 42 may be supported by the casing 30.

In addition, the upper blade 44 forms a pointed corner 45 toward the insertion opening 43 side of the lower blade 42.

The pointed corner 45 serves to directly cut the cutting object 2 supported inside the insertion hole 43 when the upper blade 44 is moved in accordance with the operation of the operation unit 50.

At this time, the upper blade 44 is advanced while maintaining a cutting angle with the lower blade 42 to sufficiently cut the cutting object (2).

Of course, the upper blade 44 is deformable to a variety of shapes, it is preferable to be made of a durable material such as a metal material so as to sufficiently cut the cutting object (2).

 In particular, when the surface to be cut by the upper blade 44 has a straight shape, the cut object 2 may cause injury to an operator.

Therefore, it is preferable that the upper blade 44 forms a convex portion 47 at the edge of the pointed corner 45.

The convex portion 47 of the upper blade 44 is formed so as to be convex in the opposite direction to the lower blade 42 side of the pointed corner (45).

Therefore, the cut surface of the cutting object 2 cut | disconnected by the convex part 47 of the upper blade 44 is formed round.

In this case, the lower blade 42 preferably protrudes the support protrusion 46 to support the convex portion 47 of the upper blade 44.

Of course, the curvature of the upper curved surface of the support protrusion 46 and the inner curvature of the convex portion 47 are preferably formed the same.

In particular, the support protrusion 46 may be detachably formed on the lower blade 42, but is preferably integrally formed.

On the other hand, the upper blade 44 is advanced in the direction of the object to be cut 2 by the operation unit 50 as the first handle 10 and the second handle 20 narrow each other by the external force.

That is, the operation unit 50 is provided inside the first handle 10 and the second handle 20 and inserted into the lower blade 42 when the first handle 10 and the second handle 20 rotate in opposite directions. It serves to cut the cutting object (2).

In this case, the operation unit 50 includes a knob 52, a sleeve 54, and an elastic member 56.

The knob 52 is formed on the second handle 20 to rotate together when the second handle 20 rotates.

In more detail, the knob 52 moves in the direction of the first handle 10 on the hinge portion of the first handle 10 and the second handle 20, that is, on the same trajectory of the circumferential surface protruding from both sides of the hinge protrusion 23. It is formed in the second handle 20.

Therefore, when the second handle 20 rotates with respect to the hinge protrusion 23, the knob 52 rotates reciprocally along the arc trajectory in the same direction as the hinge protrusion 23.

In this case, the knob 52 may be detachably formed on the second handle 20, but may be integrally formed on the second handle 20.

In addition, the knob 52 may be modified in various shapes.

In addition, the sleeve 54 is supported by the knob 52.

At this time, the manner in which the sleeve 54 is caught by the knob 52 can be variously modified, but for convenience, the sleeve 54 is illustrated as being caught while being inserted into the knob 52 by a protrusion.

In addition, the sleeve 54 connects the upper blade 44 to move forward with the knob 52 and to push the upper blade 44 toward the cutting object 2.

At this time, the manner in which the sleeve 54 connects the upper blade 44 is variously applicable.

As an example, the sleeve 54 forms a fitting protrusion 58, and the upper blade 44 forms a fitting hole portion 48 that accommodates the fitting protrusion 58.

Thus, the upper blade 44 is easily detachable from the sleeve 54.

In addition, both sides of the elastic member 56 are respectively connected to the first handle 10 and the sleeve 54. In addition, the elastic member 56 rotates the first handle 10 and the second handle 20 in the opposite direction with respect to the hinge protrusion 23 and elastically moves the sleeve 54 forward when removing the external force that narrows the gap. To restore.

At this time, the elastic member 56 is preferably made of a coil spring.

In addition, the structure in which the elastic member 56 is connected to one side of the first handle 10 and the structure connected to the other side of the sleeve 54 may be variously applied.

Of course, the elastic member 56 is preferably detachably connected to the first handle 10 and the sleeve 54.

In particular, since the sleeve 54 is hooked to the knob 52, the knob 52 is retracted in the other direction of the first handle 10 by the elastic restoring force of the elastic member 56 when the external force is removed.

At this time, the knob 52 is preferably the distance to the reverse by the elastic restoring force of the elastic member 56 is limited.

Thus, the first handle 10 forms a stopper 53 to limit the pulling of the knob 52 by the elastic member 56.

The stopper 53 serves to support the knob 52 which is formed on the first handle 10 and moves backward.

Of course, the stopper 53 may be applied in various shapes and may be detachably formed on the first handle 10, but may be integrally formed.

In addition, the upper blade 44 and the lower blade 42 are positioned inside one side of the first handle 10 and the casing 30, while maintaining a state of being superimposed on one side of the first handle 10 as much as possible. It is preferred to be manipulated. In addition, the insertion hole 43 of the lower blade 42 for inserting the cutting object 2 is preferably formed as deep as possible in the width direction within the possible range. This is to maximize the cutting force applied to the cutting object (2).

Thus, the first handle 10 forms the support member 16 to support the lower blade 42 and the upper blade 44 on both sides.

That is, the support member 16 extends to face each other at one side of the first handle 10 to support the corresponding edges of the lower blade 42 and the upper blade 44.

Of course, the supporting member 16 facing each other forms a connecting portion 17 which is connected to each other, and the connecting portion 17 is interviewed with the lower side of the lower blade 42 to detach the lower blade 42. It is preferable to.

The support member 16 may be detachably formed on the first handle 10, but may be integrally formed.

In addition, the support member 16 and the connection portion 17 can be modified in various shapes.

On the other hand, the sleeve 54, which is advanced by the external force, advances the upper blade 44 in the direction of the cutting object 2.

At this time, the upper blade 44 is preferably installed to be straight forward in the casing (30).

Thus, the support member 16 preferably forms guide grooves 18 at both inner edges to guide the straight forward and backward movement of the upper blade 44.

That is, both edges of the upper blade 44 can be linearly moved forward and backward along the guide groove 18 inside the support member 16.

Of course, the guide groove 18 may be formed on the inner surface of the casing (30).

3 and 4 show a state of cutting the cutting object 2 with a cutter.

At this time, the state in which the first handle 10 and the second handle 20 are opened as far as possible in the other direction with respect to the hinge protrusion 23 is an initial state.

In this initial state, the operator inserts the cutting object 2 into the insertion hole 43 of the lower blade 42.

At this time, the cutting object 2 is preferably in a state inserted perpendicular to the surface of the lower blade (42).

Then, when the worker grips the first handle 10 and the second handle 20 tightly, the first handle 10 and the second handle 20 rotate in opposite directions with respect to the hinge protrusion 23. Done.

Then, the first handle 10 and the second handle 20 to narrow the gap.

Accordingly, the knob 52 of the second handle 20 rotates along the arc trajectory in the same direction as the second handle 20 with respect to the hinge protrusion 23.

Thus, the knob 52 pushes the sleeve 54 forward in one direction of the first handle 10.

At this time, as the sleeve 54 is advanced, the elastic member 56 connecting the sleeve 54 and the first handle 10 is tensioned.

As the sleeve 54 is advanced, the upper blade 44 connected to the sleeve 54 is advanced along the guide groove 18 of the support member 16.

At this time, the upper blade 44 is advanced while maintaining the cutting angle with the lower blade (42).

Thus, the upper blade 44 cuts the cutting object 2 inserted into the insertion hole 43 of the lower blade 42.

 In addition, when the external force holding the first handle 10 and the second handle 20 is removed, the elastic member 56 is contracted in the axial direction by the elastic restoring force.

In the meantime, the first handle 10 and the second handle 20 are rotated so as to be opened with respect to the hinge protrusion 23.

The knob 52 rotates backward in the same direction as the second handle 20.

Thus, the sleeve 54 is reversed by pulling the elastic member 56.

At this time, the knob 52 moves backward until the stopper 53 is engaged.

In particular, since the upper blade 44 is connected to the sleeve 54, it retracts with the sleeve 54 and returns to the initial position.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom.
