Claims

[Claims for Utility Model Registration] (1) One end of a first straightedge and one end of a second straightedge are overlapped and rotatably supported on the first shaft, and the second straightedge The upper part has an arm rotatably supported at one end on a second axis parallel to the first axis, and the other end of the arm extends over the first straightedge. The straightedges are combined so as to be slidable along the longitudinal direction, and further include a holder for fixing and holding the sliding end of the arm at an arbitrary position on the first straightedge; A flexible angle ruler in which the sliding end of the arm on the first straight ruler is moved and fixed, thereby making it possible to arbitrarily adjust and fix the intersecting angle formed by the first straight ruler and the second straight ruler. (2) The ends of the first and second straight rulers that are supported by the first shaft do not extend beyond an arc with a radius of 1/2 the width of each ruler, centered on the first shaft. The flexible angle ruler according to claim (1) of the utility model registration, which is a shape. (3) The end of the arm on the third axis side does not protrude from the side of the first straightedge opposite to the second straightedge, and the end of the arm on the second axis side Utility model registration claim No. 1 characterized in that the second straight edge does not protrude beyond the side opposite to the first straight edge.
The flexible angle ruler described in (1).
