Reference numeral 5 denotes a square plate-shaped suction cup having a size and wall thickness such that it can be accommodated in the groove 1c, and a central portion of the lower surface thereof slightly protrudes from the lower surface of the groove 1c. A circular thick portion 5a is integrally formed. Further, a lifting shaft 6 is provided upright at the center of the upper surface of the plate-shaped suction cup 5 .

Reference numeral 7 denotes a circular hole for warping the suction cup formed in the lower plate part 1b of the ruler base frame 1, and 8 denotes a through hole bored concentrically with the circular hole 7 in the upper plate 1a of the ruler base frame 1. The lifting rod 6 of the plate-shaped suction cup 5 described above passes through the circular hole 7 and the through hole 8 and projects onto the upper plate portion 1b.

Reference numeral 9 denotes an operating piece, and the upper end of the lifting shaft 6 is connected to the pin 1 in the forked part formed at its base end.
It is pivoted via 0. The pivot position is located slightly below the center of the wall thickness of the operating piece 9, which allows the operating piece 9 to be inverted 180 degrees.
