When the connecting column Ⅱ6 slides in the slide groove 102, it drives the connecting rod Ⅱ4 to move, so that the connecting rod Ⅱ4 rotates with the middle part as the center of the circle. The pointer 61 is fixedly set on the connecting column Ⅱ6 and is aligned with the scale 21. When the connecting column Ⅱ6 moves, the pointer 61 slides on the surface of the scale 21.
