Claims

[Claims for Utility Model Registration] A support stand 1 having a concave portion 22 having an arcuate cross section on its upper end surface, a support stand driving means 3 for linearly moving the support stand 1 in a horizontal direction by a fixed distance, and a flat surface 12 on the upper side. has an arcuate surface 11 on the lower side and is formed into a roughly arcuate cross section, fits into the recess 22 of the support base 1 and is supported by the support base 1,
a swivel block 10 that is swingably provided within the recess 22 along its inner peripheral surface; swivel block driving means 13, 14 for rotating the swivel block 10 to a desired rotation angle;
15, 16, and 17, so that the flat surface 12, which is inclined with respect to the linear movement direction of the support base 1 due to the rotation of the swivel block 10, acts as a wedge surface due to the linear movement of the support base 1. A quantitative cutting device characterized by having the following configuration.
