Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The present invention provides the simple compass ruler shown in accompanying drawing 1-6, comprises ruler main body 1, and the surface of ruler main body 1 is provided with scale line 9, and described ruler main body 1 is provided with for fixing compasses fulcrum (can It is a gel pen, or it can be a pencil, a ballpoint pen, a positioning needle), and the center of the circle positioning through hole 3 is flush with the zero scale of the scale line 9; the damping on the ruler main body 1 A slide block 2 is connected, and the slide block 2 is positioned away from or close to the center of the circle 3 along the arrangement direction of the scale line 9, and the slide block 2 is provided with at least one device for fixing the line drawing (it can be a pencil or a Gel pen, ballpoint pen) installation through hole 4, the connection line between the center of the installation through hole 4 and the center of the circle center positioning through hole 3 is parallel to the sliding direction of the slider 2. Insert the compass fulcrum into the center positioning through hole 3, then insert the line drawing device into the installation through hole 4, move the slider 2 to the position of the target scale line 9, rotate the ruler body 1 around the compass fulcrum and pass the line drawing device Draw a circle, the operation is simple and convenient, which can greatly improve the efficiency of drawing arcs.

As shown in accompanying drawing 1 and accompanying drawing 4, described ruler main body 1 is provided with strip-shaped hole 5, and the two sides of strip-shaped hole 5 are respectively provided with a chute 6, and the two ends of described slider 2 are respectively provided with in the corresponding chute 6. The slide block 2 slides along the chute 6 in the strip hole 5 of the ruler main body 1, and it is very convenient to adjust the arc diameter.

As shown in accompanying drawing 5, on the basis of the structure in Fig. 4, the structure of the first clamping position is added. A wave-shaped groove 12 matching with the wave-shaped protrusion 11 is provided on the upper side. The wavy protrusion 11 is engaged with the wavy groove 12, which can prevent the slider 2 from loosening with the ruler body 1 during the drawing of the arc, resulting in irregular drawing of the arc, and can make the drawing of the arc more stable. .

As shown in accompanying drawing 6, on the basis of the structure in Fig. 4, the second locking structure is added. A toothed groove 14 matching with the toothed protrusion 13 is provided on the inner side. Through the snap fit between the tooth-shaped protrusion 13 and the tooth-shaped groove 14, it can prevent the slider 2 and the ruler main body 1 from loosening during the drawing of the arc, resulting in irregular drawing of the arc, and can make the drawing of the arc more stable. .

As shown in Figure 3, the upper surface of the slider 2 is provided with a button 7, and the button 7 is arranged in the middle of the slider 2, which can make the slider 2 more stable in the process of pushing the slider 2.
