【Example】

 1 to 3 are views of a first embodiment of scissors to which an office knife according to the present invention is attached. As shown in the figure, the first embodiment according to the present invention comprises scissors 1 and an office knife connected to one side of a blade 2 of the scissors 1.

The seat 2a is formed on one side of the blade portion 2 of the scissors to provide a place for installing the office knife 4, and two seats are provided at appropriate positions of the seat 2a for connecting with the office knife 4. Provide a fixing hole. Further, the office knife 4 has an upper plate 80 having a guide elongated hole 90 forming an expansion hole 90a at one end; a blade 5 having a connecting hole 5a near the one end; and two connecting protrusions protruding from the lower surface. 6, a pair of longitudinal upper plate fixing portions 20 formed in parallel to each other, a pair of longitudinally protruding inner partition walls 30 formed in parallel to each other, and formed on one side of the inner partition wall. It is composed of a sheath 10 formed of a concave and convex portion 55; a flexible portion 60 having a locking projection 70, a guide portion 60a having an insertion projection 60b, and a slider 75 made of a slider knob 50.

After the insertion protrusion 60b of the slider 75 is coupled to the coupling hole 5a of the blade 5, the blade 5 is positioned on the partition wall 30 formed in the sheath 10. The upper plate 80 is placed on the upper plate fixing portion 20 of the sheath 10. At this time, the knob 50 of the slider 75 projects through the expansion hole 90a formed at one end of the guide elongated hole 90. The width of the upper plate 80 is slightly wider than the width of the pair of upper plate fixing parts 20, and the upper plate 80 is made of an elastic thin plate. When pressure is applied, the upper plate 80 is easily fitted and fixed to the upper plate fixing part 20. .

The office knife 4 having the above-described structure has scissors by inserting the coupling protrusion 6 protruding from the lower surface of the sheath 10 into the fixing hole 3 formed in the seat 2a of the scissor blade 2. Combined with 1. At this time, an adhesive agent is used to fix the seat 2a and the lower surface of the sheath 10.

Hereinafter, an example of use of scissors provided with an office knife will be described.

That is, by moving the slider knob 50 of the office knife 4 back and forth, the blade 5 of the office knife 4 moves in and out of the sheath 10. At this time, when the slider knob 50 of the slider 75 is pushed forward and backward, the locking projection 70 of the elastic portion 60 is moved back and forth. Since the locking projection 70 of the elastic portion 60 moves back and forth along the uneven portion 55 formed on one side of the partition wall 30, the blade 5 connected to the slider 75 moves in and out of the sheath 10. When the blade 5 comes out of the sheath for a suitable length to use, the pushing action is stopped. Then, the locking projection 70 is inserted into the uneven portion 55 by the restoring force of the elastic portion 60, and the blade 5 does not move during use.

The concavo-convex portion 55 is formed on one side of the partition wall 30 so that the upper plate 80 is not separated from the upper plate fixing portion 20 by the force applied on the upper plate 80 during use of the office knife 4.

Since the upper plate 80 is made of a thin plate, it is separated from the upper plate fixing portion 20 when a bending force is applied. Therefore, the blade 5 and the slider 75 are taken out of the sheath 10 and the blade 5 is removed. Should be replaced.

The office knives 4 are combined in the reverse order.

4 to 6 are views showing a second embodiment of scissors having an office knife according to the present invention.

As shown in the figure, the second embodiment according to the present invention is a scissor 1 having two fixing holes 3 on one side of a scissor blade 2 and an office having two coupling protrusions 6 on the back surface of the scissors 1. It consists of a knife 4. The office knife 4 is a general one in which the blade 5 can be replaced at one end of the sheath. In this case, it is not necessary to form a seat for installing the office knife on one side of the blade portion 2 of the scissors as in the first embodiment, so that the scissors to which the office knife is attached can be easily installed. It can be manufactured.

7 to 9 are views showing a third embodiment of scissors to which an office knife according to the present invention is attached.

As shown in FIGS. 7 to 9 and the first embodiment, the third embodiment is composed of scissors 1 having a seat 2a on one side of a blade 2 of scissors and an office knife 4. There is. Here, the blade 5 of the office knife 4 can be separated and replaced from the upper side of the rear end of the sheath 12. The sheath 12 of the office knife 4 has a recess 21 having two coupling holes 31 on its lower surface and a detachable coupling piece 41 having two insertion protrusions 51 corresponding to the coupling holes 31.

After the coupling hole 5a of the blade 5 and the protrusion (not shown) of the slider 40a shown in FIG. 9C are coupled as described in the first embodiment, the blade 5 and the slider 40a are separated from each other. It is placed in the sheath.

The blade 5 moves in and out of the sheath as the slider knob 40 moves back and forth.

As shown in FIGS. 9A, 9B, and 9C, when the blade 5 of the office knife 4 is replaced, the connecting piece 41 is separated from the sheath 12 and the slider knob 40 is moved to the end of the sheath 12. When pushed to the part, the slider 40a comes out from the sheath 12. At this time, when the blade 5 connected to the slider 40a is short, the blade 5 and the slider 40a can be taken out from the sheath 12 together, but when the blade 5 is long, after the slider 40a and the blade 5 are separated, After the slider 40a is taken out of the sheath through the recess, the sheath 12 is slanted so that the blade 5 starts sliding.

In the first, second and third embodiments of the present invention, as shown in FIGS. 1, 4, 5 and 7, a blade insertion slit 100 for breaking a part of the blade 5 of the office knife 4 is provided. Formed on one side of the handle 105 of the scissors 1, the user can use the new part of the blade 5 by removing the old part of the blade 5.
