Abstract
The utility model relates to a multi-purpose drawing ruler, which belongs to the technical field of stationery fabrication. The utility model comprises a main ruler and a second ruler. A semicircle protractor is arranged on the main ruler, a rotary shaft is arranged at the center of the semicircle protractor, and a pointer-type ruler is hinged on the rotary shaft. The secondary ruler is combined with the main ruler through a sliding groove, and a boss is arranged at the intersection part and clamped into the sliding groove. The secondary ruler is perpendicular to the main ruler. A fastening button is arranged on the secondary ruler, and can be used to freely position the secondary ruler on the main ruler. For use, outer side of the main ruler is used to draw straight lines, the pointer-type ruler on the semicircle is used to draw angle sides, and the main ruler and the second ruler are used together to draw parallel lines or rectangles. The utility model can fulfill drawing demands of students, and is featured with easy and quick use.
Description
Technical field
The utility model relates to a kind of multifunctional drawing ruler, belongs to stationery manufacturing technology field.
Background technology
Existing various ruler, no matter be ruler, or T-square, perhaps all there are some shortcomings in some other multi-functional ruler, exactly can't realize with one the ruler equidistant straight line that draws the angle or the polygon of any angle between the 0-180 degree of drawing.Promptly use a ruler to draw, step is many, and is not easy to operate.
Summary of the invention
The utility model provides a kind of reasonable in design, convenient and practical multifunctional drawing ruler at the deficiencies in the prior art.
The purpose of this utility model is achieved through the following technical solutions: a kind of multifunctional drawing ruler, by main scale, secondary chi is formed, wherein main scale is provided with half garden protractor, protractor center, half garden is provided with rotating shaft, is hinged with a pointer chi plate in the rotating shaft, and secondary chi combines with main scale by chute, the joint portion is provided with a boss, sticks in the chute.
Secondary chi keeps right-angle relationship on main scale.
Secondary chi is provided with a tightening knob, arbitrarily the position of fixed joint chi on main scale.
When the utility model used, straight line was drawn in the available main scale outside, draws angle line with the pointer chi plate on the half garden chi, cooperates with major and minor ruler to draw parallel lines or rectangle.Use this structure one cover drawing rule, can satisfy student's needs of drawing, uses very convenient fast.
Description of drawings
Accompanying drawing is the utility model structural representation.
Wherein: 1, main scale, 2, secondary chi, 3, pointer chi plate, 4, tightening knob, 5, chute.
The specific embodiment:
Embodiment: structure as shown in drawings.Form by main scale 1, secondary chi 2, pointer chi plate 3, tightening knob 4, chute 5, wherein, main scale is provided with half garden protractor, and protractor center, half garden is provided with rotating shaft, be hinged with a pointer chi plate in the rotating shaft, secondary chi combines with main scale by chute, and the joint portion is provided with a boss, sticks in the chute, when secondary chi is slided on main scale, keep right-angle relationship with main scale, also be provided with a tightening knob on the secondary chi, arbitrarily the position of fixed joint chi on main scale.During use, straight line is drawn in the available main scale outside, draws angle line with the pointer chi plate on the half garden chi, cooperates with major and minor ruler to draw parallel lines or rectangle.
