Abstract
The utility model relates to daily supplies, in particular to a compass for drawing fixed-angle circular arcs. The novel compass comprises a spindle, a hinge, a left compass leg, a right compass leg, a pen, a dial, a pointer, a compass point, leg fixing brackets, a pen point and a pen head. The spindle is connected with the hinge through a screw, and the left and right compass legs are fixedly connected with the hinge through a connecting shaft. The pen is mounted at the bottom of the left compass leg through another connecting shaft and can rotate leftwards and rightwards around the connecting shaft. The pen point is fixedly connected with the lower end of the pen through another screw, and the pen head is fixedly connected with the lower end of the pen point. The pointer is connected with the middle portion of the right compass leg, and the dial is fixedly connected with the middle of the right compass leg with the same as a shaft and attached to the surface of the pointer. The compass point is fixedly connected with the lower end of the right compass leg, and the leg fixing brackets are connected with the lower portion of the right compass leg and capable of overturning up and down. The novel compass has the advantages that the defect that a conventional compass can only be used for drawing unknown-angle circular arcs is overcome.
Description
Technical field
The utility model relates to a kind of articles for daily use, and especially a kind of picture is decided angle circular arc compasses.
Background technology
The compasses kind of Cun Zaiing is a lot of in the market, nearly all type all can only be painted the circular arc of unknown angle, yet in actual drawing work, many times all need picture to decide the circular arc of radian, traditional compasses one like this are that the picture circular arc is difficult for accurate its radian size, the requirement hornwork, very inconvenient, and not too economical; The 2nd, when picture is decided the radian circular arc, need to alter, waste time and energy, efficient is poor.
The utility model content
The utility model is intended to address the above problem, and a kind of novel bow compass is provided, and it has overcome it and has overcome traditional compasses and can only draw unknown angle circular arc and drawback consuming time, waste materials, and its technical scheme that adopts is as follows:
A kind of picture is decided radian circular arc compasses.Comprise rotating shaft, hinged joint, left side compasses leg, right compasses leg, handwriting, dial, pointer, the compasses point, Gu foot support, nib and nib, described rotating shaft is connected with hinged joint by screw, described left compasses leg, right compasses leg is affixed by connecting axle and hinged joint, described handwriting is loaded on left compasses leg lower end by connecting axle also can be around the connecting axle left-right rotation, described nib is affixed by screw and handwriting lower end, described nib and nib lower end are affixed, described pointer is connected with right compasses leg middle part, described dial serves as that axle is fixed on the leg middle part with right compasses leg, described compasses point is affixed with right compasses leg lower end, and described solid foot support is connected in right leg bottom and can spins upside down.
The utlity model has following advantage: simple in structure, easy to use, the ingenious combination of protractor and compasses, it is more time saving and energy saving to make picture decide the radian circular arc, improves mapping efficient.
