Description

Stationery cutter knife

The present invention relates to a stationery cutter knife. More specifically, the cutter blade is cut using a blade cutter in a state in which the cutter blade is not separated from the case, and the cutter blade inserted into the blade cutter is cut by the compressive force of the cutting blade and then safely received into the recovery groove. It is about a cutter knife.

As a cutting tool of the general cutter blade 30, a cover 10 mounted at the end of the stationery cutter knife case 20 is used as shown in Figures 1a and 1b. The cover 10 serves as a blade cutter 40 and is used separately from the case 20 when cutting the blade.

As shown in FIG. 1B, an insertion groove 11 is formed inside the cover 10, and the cutter blade 30 is inserted into the insertion groove 11 to be in close contact with the cover 10, and then moved upward and downward by applying an appropriate force to the cover 10. The cutter blade 30 is cut.

However, when the proper force is not applied to the cover 10 or when the angle of both hands is slightly distorted, the cut blade 30a may pop out, resulting in a risk of injury, and the recovery of the cut blade 30a. Not only not easy, the blade also had a problem that is not properly cut based on the cutting guide 31.

In addition, the hassle of having to separate the cover 10 from the cutter knife case 20 for cutting the cutter blade 30 is also pointed out as a problem.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, the main purpose of cutting the cutter blade is that the cutter blade is inserted into the through groove of the cutting piece in the state that the blade cutter is not separated from the case. It is intended to provide a stationery cutter knife that can be safely accommodated in the recovery groove after being cut by the rotational compression force.

Hereinafter, with reference to the accompanying drawings the technical configuration and effects of a preferred embodiment that can achieve the object of the present invention is as follows.

Figure 2 is an exploded perspective view of the cutter knife for stationery of the present invention, Figure 3 is a perspective view of the blade cutter of the present invention.

As shown in FIG. 2, the blade cutter 40 is pressed into the cutter knife case 20 in which the adjustment wave groove 21 for adjusting the protrusion length of the cutter blade 30 is formed, and the cutter blade 30 Inserted into the through groove 42 of the blade cutter 40, the cover 10 is fitted to the end of the case 20.

The blade cutter 40 is composed of a cutting piece 43 formed with a cutter body 41 and a cutting protrusion 44, the cutter body 41 and the cutting piece 43 is smaller than 90 ° while contacting one side with each other It is formed in the form of an acute angle, the through groove 42 through which the cutter blade 30 penetrates is formed in the cutter body 41.

As the material of the blade cutter 40, a synthetic resin having excellent elasticity capable of smoothly moving the upper and lower elastic movements of the cutting piece 43 is used, or the upper half is made of synthetic resin, and the lower half is made of rubber. The material is used, which is because when the blade cutter 40 is inserted into the case 20, a portion of the rubber material is completely adhered to the bottom surface of the case 20, so that the cut blade 30a is cut into the case 20. This is because the function of the recovery groove 50 is improved as it is not discharged to the rear.

The upper surface of the front end portion of the case 20 is formed with a cutting opening groove 22 through which the cutting protrusion 44 of the blade cutter 40 can be penetrated at the time of cutting the blade, and has the same shape as the cut blade pieces 30a. Is formed. That is, the cutting protrusion 44 of the blade cutter 40 and the cutting opening groove 22 and the blade piece 30a of the case 20 have the same shape.

Figure 4a is a cross-sectional view showing an embodiment for cutting the cutter blade 30 by using a knife cutter 40 inserted into the case 20, as shown in Figure 4a is already inserted into the through groove 42 The cutting guide 31 of the cutter blade 30 is positioned at the tip of the blade cutter 40 and then cut and cut by the rotational compression force applied to the cutting protrusion 44 of the cutting piece 43. The cutting piece 43, which is safely received into the recovery groove 50 and at the same time completed the cutting mission, is returned to its original position by the elastic force of the synthetic resin.

In order to ensure that the cutting guide 31 of the cutter blade 30 is positioned at the tip of the blade cutter 40, the continuous spacing of the adjusting wave groove 21 for adjusting the protruding length of the cutter blade 30 may be cut. What is necessary is just to form it easily.

In addition, the recovery groove 50 is a space formed with the inclined surface 23 of the case 20 while the front end of the blade cutter 40 inserted into the case 20 is caught by the inclined starting point P of the case 20. , This space becomes a recovery groove 50 for receiving the cut blade (30a).

Figure 4b is a cross-sectional view of another embodiment for cutting the cutter blade 30 of the present invention, has the same configuration as Figure 4a. However, in one embodiment of Figure 4a, the cutter body 41 and the cutting piece 43 is formed integrally in the form of an acute angle while contacting one side with each other, in the other embodiment of Figure 4b the cutter body 41 and the cutting piece One side of the 43 is rotatably connected via the hinge 60, and a spring 61 is installed between the bottom face of the cutting piece 43 and the upper surface of the cutter body 41 to allow the cutting piece 43 to be cut. Cut through the cutter blade 30 is configured to elastically return to the original position.

As described above, although the preferred embodiment according to the present invention is illustrated and described, the present invention is not limited to the above-described embodiment. That is, the blade cutter 40 can be made of a transparent body and an opaque body, and the material may also be used other than synthetic resin and rubber, and the connection structure of the cutter body 41 and the cutting piece 43 is also designed. Various changes and modifications may be made by those skilled in the art.

Stationary cutter knife equipped with a knife cutter as described above is not only convenient because the knife cutter does not have to be removed from the case when cutting the blade, but also a problem that the conventional blades are not protruded or cut properly when cutting. By overcoming the problem, cutting of the cutter blade can be performed more safely and quickly.
