A rotary pin 10, a motor 8 for rotating the cutting edge 4, and additionally a cover 6 of the cutting edge 4, and a handle 9.

In the following, the operation relationship of the conventional grinding machine configured as described above will be described.

When the pipe 3 is placed on the top of the base 2 placed on the ground, and the pipe 3 is perpendicular to the cutting edge 4, the pipe 3a is moved to the fixed plate 5b fixed by moving the fixing plate 5a from side to side. 3) is pressed and fixed.

When the motor 8 is operated, the cutting edge 4 rotates. At this time, when the operator grasps the handle 9 and applies a force downward, the grinding machine 1 is centered on the first rotary pin 10. The pipe 3 is cut vertically while turning in the direction of the applied force.

However, since the base 2 is plate-shaped, it is difficult to fix the pipe already installed by the fixing plates 5a and 5b formed on the top of the base 2, and during the cutting, the friction generated by the rotation of the cutting edge 4 is cut. When the grinding machine 1 moves, the cutting blade 4 is inserted into the cutting groove to be cut and destroyed.

The fragments of the cutting edge 4 thus broken can run in all directions, and the fragments can cause disaster to those around them.

Even if such a disaster does not occur, the cutting surface is not cut vertically by the movement of the grinding machine 1, and a clean cutting surface cannot be obtained.

The present invention is provided to solve the problems of the prior art as described above, the object of the present invention is to provide a fastener of the cutting device to have a precise cutting and a clean cutting surface by fixing the cutting device to the position to be cut. .
