Further, the mutual spacing between the upper cutting blades 4 and the mutual spacing between the lower cutting blades 5 may be appropriately determined depending on the curved surface of the tile to be cut.

The embodiment of the present invention is constructed as described above, and by aligning the cutting part of the tile with the cutting line of the upper and lower cutting blades 4 and 5 and rotating the operating arm 3, the upper and lower cutting blades 4 and 5 can be cut. .

In addition, with respect to the movable operation trajectory of the operation arm 3,
Since the cutting lines of the lower cutting blades 4 and 5 are arranged at a certain angle, the tiles can be cut in a more natural posture, and the intended cutting position of the tiles can be easily confirmed, which also makes the work easier. Efficiency can be improved. Furthermore, the amount of tiles inserted into the pocket space 6 can be reduced, and interference with the frame body 2 can be prevented.

Further, according to this embodiment, the upper and lower cutting blades 4 and 5 are supported by the respective mounting bodies 34 and 21, and the mounting bodies 34 and 21 are pivotally connected to the upper and lower supports 27 and 14 so as to be able to swing freely. Therefore, as shown in Figure 7,
Even if the material to be cut K is inclined or has a curved cross section, the upper and lower cutting blades 4 and 5 will be able to cut the material K by swinging around the mounting pins 33 and 22 of each mounting body 34 and 21. This ensures that it comes into contact with the top and bottom surfaces of the Therefore, the material to be cut K does not rotate in the direction of the arrow as in the conventional case, and regardless of the inclination angle and curved shape of the material to be cut, it can be cut almost as it is, which is extremely convenient. Stable workability can be obtained.

Further, the upper and lower cutting blades 4 and 5 are provided in pairs, and are arranged in series at positions displaced back and forth in the cutting line direction of the material to be cut K with respect to the respective mounting pins (horizontal axes) 33 and 22. Therefore, when cutting the material K, it is possible to cut the material K along the desired cutting line.
