The present invention relates to a safety cut for cutting the paper using a knife or ruler in the past when cutting the paper using office or stationery. As a result, when cutting along the sides of the ruler while pressing the ruler with one hand, holding the knife with the other hand, the knife was missed and the hand was injured or the desired cutting point was missed. This requires user inconvenience and safety.

In addition, there was a groove at the top of the ruler to cut it using elasticity. When replacing the blade, the whole sheath must be replaced, not the method of replacing only the blade. When the sheath moves elastically, the blade comes out of the ruler and hurts. There are a lot of possibilities, and even when carrying a bag or other, there is a risk that the blade will come out and get hurt. Also, when cutting paper, it is difficult to control the depth of the blade because it depends on the senses.

In order to secure the advantages and disadvantages of the above, the sides of the ruler were wrapped in a c-shape and grooves were provided in the rail to prevent any detachment, and springs were used so that the blades entered and exited constantly. It is a structure that is cut only by the depth, and the blade is tightened with bolts, and if the blade is not used, it can be replaced with a cutter blade that is generally used.

The present invention has been devised to solve the above problems, and the groove 12 is formed on one side of the body of the body 1, in which the room is drawn, with a predetermined length, and the bottom surface also has a step and the step (15). ), The body of the ruler and the c-shaped cutlery (4) is wrapped and fastened and coupled, and the spring (6) is inserted and coupled between the knife holder (4) and the sheath (2), and the spring (6) also has a constant elasticity. It is very important and there is a groove to cut the sheath (2) in the middle of the cutlery (4), and the locking jaw (10) is located on both sides of the middle of the cutlery (4) to prevent the sheath (2) from being separated and the sheath ( 2) There is also a hook (7) on both sides is fastened to prevent the movement of the spring (6) there is a spring fixing protrusion (9) on the upper surface of the knife base to prevent movement. In addition, there is a nut groove (8) to fasten the blade (5) in the middle of the sheath (2), and when replacing the blade (5), it is possible to loosen the knife tightening bolt (3) and replace it with a general cutter blade (5). It is a very important task that the blade 5 is coupled to one side of the ruler (1) is very important, and when the body (1) and the knife holder (4) is combined, the knife holder (4) is thicker than the body ruler (1) It is important to be able to move smoothly when the small amount of cutlet (4) injection material is also composed of acetal material slip smoothly.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

First, the present invention will be described with reference to FIGS. 2A, 2B, and 2C.

Body (1), sheath (2), knife bolts (3), knife holders (4), blades (5), the spring (6) is combined to form a pair.

As long as a certain length on one side above the body (1) has a groove (12) and step (13) on the upper side, the sheath (2) no longer serves to prevent the advance departure and a certain height on the lower side There is a step (15) of the groove 12 and the step (13) of the upper surface, and the step (15) of the lower surface acts as a rail [Fig. 2b] the portion of the c-shaped cutlery (4) wrapped around the force Combination to prevent separation, as shown in Figure 2c so that the scabbard (2) in the middle of the knife base (4) can be combined, so that the hook (7) of both sides of the sheath can be fastened to both sides of the groove crushing There is a locking jaw (10) to prevent the departure of the sheath (2).

As shown in Fig. 2a, the spring 6 is bound between the spring fixing protrusion 9 and the sheath 2 on the upper side of the cutlery 4 so that the sheath 2 is raised upward and is always elastic to enter a certain depth. When cutting by pressing the sheath (2) is always to move up and down (17) as much as the gap between the sheath (2) and the knife (4). In addition, the groove (16) made to fit the blade (5) beneath the sheath (2) has a step by the thickness of the blade (5) to prevent the blade (5) to move from side to side, and the blade (5) from the bottom through the sheath ( 2) Tighten with knife tightening bolt (3) in the nut groove (8) in the middle is assembled. When replacing the blade (5), only the small cutter knife blade (5), which is generally used, can be replaced, so it can be used semi-permanently.

Cutlery (4) and sheath (2) to the body (1) made of a pair of wrapped in a U-shape is fastened and coupled.

Referring to Fig. 3a and Fig. 3b, the operation sequence is shown by aligning the side 14 of the body to the ground to be cut and pressing the sheath 2 so that the cutlery 4 is close to the surface to be cut. When the knife holder (4) and the knife blade (5) move along the rail groove (12) and press down, the knife blade (5) comes down by cutting force (18) and cuts the spring (6) when it is released from the sheath (2). By the blade (5) is raised up again (17) can be easily cut again by moving the sheath (2) and the knife tray (4) to the desired position, where you want to cut on the side 14 of the body when cutting Press the sheath (2) vertically or horizontally in accordance with the pull is configured to continue cutting.

Referring to Figure 2a, as described above, the present invention has a grid scale drawn on the body 1 so that it can be easily cut to fit the desired length, and only the blade 5 can be replaced, which is very economical and only when cutting. (5) is protruded to be very safe and the body structure (1) and the knife base (4) is a coupling structure wrapped in the c-shape to prevent the separation of the blade (5) is not cut at once (18) Can also continue to cut in the same position and the blade (5) is to enter the ground only a certain depth (18), so that the ground is cut to a certain depth and can be safely and easily cut.
