Problems solved by technology

[0002] Commonly used rulers include straightedge, triangular ruler, semicircular ruler, etc. These rulers have to be lifted up after drawing to be able to move, and it is annoying to use for a long time. In the era of fast and fast everything, inflexible rulers are eliminated
In the prior art, there is only a cylindrical ruler, and there is no combination of circle and straightness. It will roll when used, and the movement is unstable, which will affect the line drawing

Embodiment Construction

[0012] The invention will be further described below in conjunction with the drawings and embodiments:

[0013] figure 1 Among them, a round and straight ruler, the cylinder 1 is sealed at both ends, the center of both ends is open, the surface of the cylinder 1 has a scale 4; the oblique end surface of the straight piece 2 has a scale 4, and a straight piece 2 The two ends are connected to the connecting edge 3 to form a ruler with grooves, and each connecting edge 3 has a screw hole 5 at its end.

[0014] figure 1 In the embodiment shown, the two screw holes 5 of the two connecting edges 3 are pressed against the holes at both ends of the cylinder 1, and the screws 6 are tightened to form a quick-moving drawing ruler. One hand grasps one straight piece 2 and the other straight piece 2 Stick the drawing paper low and draw the line with the pen in the other hand.

[0015] figure 1 In the illustrated embodiment, the screw 6 is unscrewed to become two independent square rulers and ...

Abstract

The invention discloses a cylinder and straight piece integrated ruler. A cylinder is in a cylindrical shape, two ends of the cylinder are sealed, openings are formed in the centers of the two ends, and scales are arranged on the surface of the cylinder. The number of straight pieces is two, each straight piece is in a trapezoidal shape, scales are arranged on the surfaces of the inclined ends of the straight pieces, two ends of the straight pieces are connected with connecting sides to form the ruler with grooves, and screw holes are formed in the end of each connecting side. When the ruler is used, the screw holes of the connecting sides are attached to the holes in the two ends of the cylinder, screws are screwed on the screw holes, one straight piece is grabbed by one hand, the other straight piece is attached to drawing paper in a lower manner, and a pen is grabbed by the other hand to draw lines. Moving and drawing are rapid, and the ruler can be divided and disassembled to be used.

Description

Technical field [0001] The present invention relates to stationery, which refers to a ruler that is round and straight. Background technique [0002] Commonly used rulers include straightedge, triangle ruler, semicircle ruler, etc. These rulers must be lifted after drawing before they can be moved. It is annoying to use for a long time. In an era when everything is fast and fast, inflexible rulers are eliminated. . In the prior art, there is only a cylindrical ruler, and there is no integration of the circle and the straight. When it is used, it will roll and move unstable and affect the line drawing. Summary of the invention [0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a round and straight ruler. A ruler is composed of a square ruler and a cylinder ruler. The line can be drawn on the square ruler or the cylinder ruler, mainly after drawing. Can move quickly to draw the next line, saving time, and can move diagonally. ...
