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

As shown in FIG. 1, the present invention forms a rail groove 1 on the side of the knife body 10 so that the reciprocating body 20 can move back and forth.

In the reciprocating body 20, a rail 21 is formed on the inner side of the leg, and the rail 21 is fitted into the rail groove 1 of the knife body 10 to reciprocate.

A rotary body 3 is formed at the rear of the knife body 10 to be rotated by the shaft 4, and a tooth 22 is formed at the lower end of the leg of the reciprocating body 20 so that the tooth 22 is a rotary body. The gear tooth (5) of (3) is passed up by the upper side. Then, the rotating body 3 rotates in accordance with the operation of pulling and pushing the reciprocating body 20.

The rotary blade 6 is attached to the shaft 4 of the rotary body 3, and the rotary blade 6 rotates with the rotation of this rotary body 3. This enables cutting of dices, which will be described later. In front of the rotating body 3, horizontal blades 7 are horizontally installed on the upper part, and vertical blades 8 are vertically installed at a plurality of heights at regular intervals.

On the other hand, the front and rear of the reciprocating body 20 is composed of a shape in which the handle 23 is erected slightly about 30-35 degrees from the horizontal. Handle 23 is to hold the place by hand to facilitate the pulling and pushing the reciprocating body 20

The fastening part 25 is comprised in the upper surface of the reciprocating body 20, and the cover 27 is assembled on it. The lid 27 has a built-in elastic body 28 which is a pressure spring. Thus, when the radish is put into the fastening portion 25 and covered with the cover 27, the radish is lowered below the fastening portion 25. In the case where the radish is large, it may be cut to a size that can be properly inserted into the fastening portion 25.

After mounting the radiator to the fastening portion 25, take the reciprocating body 20 to the knife body 10 to assemble the rail 21 into the rail groove (1). And when the handle 23 is pulled and pulled down the fastening portion 25, the radish is cut down vertically by hitting the horizontal blade (7), and further proceeds to the horizontal cut by the horizontal blade (7)

And the square blade enters long in the form of a rotary blade (6) is rotated to cut into diced form to drip off

When pulling the reciprocating body 20, the stepped portion 66 is formed at the rear to prevent the reciprocating body 20 from being pushed from the end of the pulling or from the knife body 10.

Thus, after pulling the reciprocating body 20, the limit of the pulling distance is given so that it does not escape from the knife body 10 so that there is no disconnection of the continuous back and forth reciprocating motion flow.

The operation thereof will be described in more detail with reference to FIG. 2 below.

As shown in Figure 2, when the primary cutting by the vertical blade (8) is made, the vertical cutout portion 11 is formed in the radish and at the same time the secondary cutting is made while passing through the horizontal blade (7) 12) is made and finally the rotary blade (6) is rotated and raised from the bottom up to the length of the sputum mochi cut into a certain length to create a longitudinal incision (13). The longitudinal cutout portion 13 breaks out of the cube-shaped dice 14 by a predetermined length by the rotary blade 6 rotating and cutting.

The rotation of the rotary blade 6 rotates and cuts the rotary blade 6 by the force because the rotating body 3 rotates by pulling the handle 23. In this case, as shown in FIG. 1, the elastic body 28 embedded in the cover 27 is always pressed down on the radish, so when the above cutting operation is finished, the radish is lowered down again, and the same cutting operation is performed again.

The following describes the slicing operation.

3 is a separate cutting knife 30

The knife 30 is formed with a protruding pin 31 on the lower left side, the blade 32 is formed on the right end protruding.

The blade 32 forms a concave engaging portion 33 at regular intervals.

The coupling hole 31 of the chakal 30 is coupled to the engaging projection 35 formed in the knife body 10 shown in Figure 1 to prevent movement. In this case, the stepped portion 36 is provided at the lower end of the chapel 30 side leg so that the stepped portion 36 spans the side top portion 37 of the knife body 10. Thus, the knife 30 is allowed to span without falling into the space 38. Then, the vertical blade 8 is positioned in the coupling portion 33 formed between the blades 32 so that the blade 32 and the vertical blade 8 are located side by side at the same interval. Therefore, it is possible to slice vertically at regular intervals. And after passing the vertical blade (8) at the same time is to be cut by the horizontal cutting by the horizontal blade (7)

In the above, the vertical blade (8) and the blade 32 is the upper surface of the blade as shown in Figure 3 to be made of the unprocessed surface 39 (the lower vertical portion and the blade of the recessed groove 41) Is made of the machining surface 40

The reason why the recessed grooves 41 are formed is to prevent them from being heard when grinding radish.

When radishes are cut, radishes are caught on the blade and always lifted up, so the radish is formed in the shape of a hook to prevent the radish from being lifted. To avoid injury

4 is another embodiment of a reciprocating body 20.

As shown in the present embodiment, the insertion hole 24 is formed at the rear of the reciprocating body 20 so that the rear cover 45 can be inserted and mounted. The rear cover 45 formed a vertical blade hole 44 vertically.

A side of the rear cover 45 may be provided with a locking jaw 60 to be tightly fitted into the insertion hole 24. Or it may be made of other rail configuration for mounting the rear cover 45, of course.

The function of the rear cover 45 is to drop the last remaining radish pieces from the knife body 10 when the cut radish cut of the radish mounted on the fastening part 25 is completed. That is, when the handle 23 is pulled out in a state in which the reciprocating body 20 is mounted on the knife body 10, a longitudinal blade hole 44 is formed in the rear cover 45 to pass through the horizontal blade 7. can do. At this time, since the rear cover 45 covers the entire periphery vertically and pulls it out, the vertical blade 8 of the knife body 10 and the residues of the dices remaining on the rear can be removed by pushing.

5 is an embodiment for improving the assembly of the knife body 10

As shown in FIG. 1, since the knife body 10 has a complicated structure, a configuration example of an assembly part for facilitating assembly thereof is illustrated in FIG. 5.

However, the present invention is not limited to the assembly structure of this embodiment.

As shown in FIG. 5, in this embodiment, the rotatable assembly 51 is assembled to the main frame 50 of the knife body 10.
