[0013]

[Invention of claim 1] When the object to be cut is chopped by the chopping device according to claim 1, the main body case together with the operating rod is once removed from the object to be cut storage case, and is placed in the object to be cut storage case. Store the object to be cut, and reattach the main unit case to the object storage case together with the operating rod.

Then, while holding the main body case with one hand to prevent its rotation, the upper end of the operating rod is pushed down with the other hand, and the operating rod is lowered together with the cutting blade at the lower end. After the cutting blade cuts the object to be cut, the hand is released from the upper end of the operating rod.

When the upper end of the operating rod is pushed down by the other hand while holding the main body case with one hand to prevent its rotation, the cylindrical body attached to the operating rod descends in the cylindrical portion of the main body case. While rotating in a certain direction. Therefore, the cylindrical body is rotatable only in the certain direction with respect to the actuating rod by the reverse rotation preventing means, and the actuating rod is not rotatable because the upper end thereof is manually pushed. Therefore, the cylindrical body attached to the operating rod rotates in the certain direction with respect to the operating rod. That is, when the operating rod descends, only the cylindrical body attached to the operating rod rotates in the certain direction, and the operating rod and the cutting blade attached to the lower end of the operating rod do not rotate. In other words, the cutting blade descends vertically without rotating and cuts the object in the object storage case.

After the cutting blade cuts the object to be cut, when the hand is released from the upper end of the operating rod, the operating rod is returned to the upper position by the return spring together with the cutting blade. The cylindrical body attached to the actuating rod rises in the cylindrical portion of the main body case and rotates in the opposite direction. However, since the cylindrical body is rotatable only in the predetermined direction with respect to the operating rod by the reverse rotation preventing means and does not rotate in the opposite direction to the operating rod, the operating rod and the cutting blade together with the cylindrical body. Rotate in the opposite direction.

In this way, when the operating rod descends,
Only the cylindrical body attached to the operating rod rotates in the certain direction, the operating rod and the cutting blade attached to the lower end of the operating rod do not rotate, but when the operating rod rises, the cutting rod and the cutting blade are cut. The blade rotates with the cylinder in the opposite direction. That is, by repeating the vertical movement of the operating rod, the cutting blade at the lower end of the operating rod gradually rotates in the opposite direction. Therefore,
As a result of sequentially cutting the cut object in the cut object storage case at different angles, the cut object is chopped.

[Invention 2] When the operating rod is moved up and down while the cutting blade is vertically inserted into the cutting blade through hole of the dust removing plate, the dust removing plate is cut without moving vertically. Since the blade is rotated together with the blade, scraps and the like of the object to be cut attached to the cutting blade are scraped off from the cutting blade by the dust removing plate when the cutting blade is raised. Therefore, it is possible to prevent dust and the like from being cut into the main body case above the dust removing plate.

[Invention of Claim 3] Since the cutting blade is formed by bending a plate-like body into a fold shape, the object to be cut in the object storage case is cut at a plurality of positions at the same time. Therefore, the cutting efficiency is improved.

[Invention of Claim 4] Since the cutting blade is attachable to and detachable from the operating rod, cleaning of the cutting blade, the inside of the main body case and the like is easy.

[Invention of Claim 5] Since the object storage case is transparent, it is possible to visually check the chopping condition during the chopping work.

[Invention of Claim 6] When the bottom of the object storage case is removed, the object placed on the cutting board can be chopped by a chopping device (see Fig. 3).
