Abstract

The multifunctional ruler consists of main ruler and auxiliary ruler, the main ruler is rectangular plate with protractor, four sides are marked with scales, and the multifunctional ruler has the functions of various common rulers.

Description

Multipurpose ruler

The utility model relates to a kind of multifunctional ruler, especially about the tailoring rapid drafting, and can collect the multi-functional combination ruler of the function of compasses, protractor, engineer's scale, ruler, set square, template.

Commercially available multifunctional ruler just possesses 3～4 kinds of common functions simultaneously now, does not possess function more than six kinds, and existing garment-cutting scissors tailor's measure can not be accomplished quick, convenience in use, and does not possess the function of other chis.

The purpose of this utility model just provides a kind of cloth-cutting quickly and easily drawing of adapting to, and has multi-functional tool ruler.

Technical solution of the present utility model is: a kind of multifunctional ruler, main scale and secondary chi by coupling or separately use are mutually formed, it is characterized in that: main scale is a rectangular slab, protractor is arranged on it, the straight flange of protractor parallels with the long limit of main scale, on rectangle four limits of main scale, indicate scale respectively, secondary chi is the square plate that the corresponding size relation is arranged with main scale, also indicate scale on four limits of secondary chi, also have aperture on the scale of correspondence, the angle and the protractor initial point of secondary chi link.

The center line on the 90 ° of lines of the protractor on the described main scale and the long limit of main scale coincides, and the scale on the main scale on the long limit relative with the protractor arc section is to be the scale that marks to two ends respectively zero point with the center line of growing the limit, does not have the scale place at main scale, has pattern hole.

Described secondary chi, its center have a square hole, and every limit in hole is corresponding parallel with every outside of secondary chi, also has pattern hole at the no scale place of secondary chi.

It is many that the utility model compared with prior art has function, and the characteristics that the scope of application is wide, easy to use, volume is little, carry are easily especially used in clothing drafting, have more quick practical characteristics.

Fig. 1 is major and minor chi coupling figure of the present utility model.

Fig. 2 is a main scale plane of the present utility model.

Fig. 3 is a secondary chi plane of the present utility model.

Below in conjunction with accompanying drawing embodiment of the present utility model is described: main scale and secondary chi all are to be made by lucite or plastics, main scale is a rectangular slab, protractor is arranged on it, indicate scale all around, is to mark (Fig. 2) respectively to two ends zero point at the scale on b limit with the mid point on this limit, have pattern hole (circular hole of all size, square hole, delthyrium elliptical aperture etc.) at no scale place, 90 of protractor ° of lines overlap with the center line on long limit on the main scale, have scallop hole in the protractor.Secondary chi is a square plate, has square hole on secondary chi, indicates scale all around, has aperture on the scale of correspondence, and hole diameter is 2～3 millimeters, also has pattern hole (Fig. 3) at no scale place.

Claims
