Detailed description of the invention
As depicted in figs. 1 and 2, a kind of plane circular arc scoring tool, rule 1 initiating terminal is fixedly connected with locator 2, positioning sliding block I 3 and positioning sliding block II 4 is provided with from left to right successively on the right side of locator 2, rule 1 all runs through positioning sliding block I 3 and positioning sliding block II 4, positioning sliding block I 3 upper surface is run through and is provided with center of circle pilot pin 5, tip position is downward, elastic device is provided with between center of circle pilot pin 5 and positioning sliding block I 3, locator 2 upper surface is run through and is provided with marking-off pin 6, positioning sliding block II 4 lower surface is provided with universal wheel 7, marking-off pin 6 needle point, the lower surface of center of circle pilot pin 5 needle point and universal wheel 7 is in same level, rule 1 and locator 2 fixedly connect.
Preferably, described positioning sliding block I 3 and positioning sliding block II 4 are provided with locking knob 8.
As shown in Figure 2, preferably, described center of circle pilot pin 5 is notch cuttype column structure, top diameter is greater than below diameter, minor diameter cylinder mid portion is provided with groove 9, and groove 9 width is corresponding with rule 1 width, and rule 1 runs through positioning sliding block I 3 and is slidably connected with groove 9 simultaneously.
