Abstract
The utility model relates to a tool for teaching and studying, and in particular relates to a multifunctional compass. The utility model provides the following technical scheme: the multifunctional compass comprises two straight rods which are respectively a scribing rod and a locating rod, wherein the scribing rod and the locating rod respectively comprise a hinged end and a working end; the locating rod is articulated with the hinged end of the scribing rod; the working end of the locating rod is provided with a locating needle; the working end of the scribing rod is provided with a scribing pen core; a folding straight plate which is hung by an elastic contracting part is arranged at the part at which the locating rod is articulated with the scribing rod; and the straight plate is provided with scales. Due to the adoption of the technical scheme, the multifunctional compass which can realize location and measurement without needing the help of other measuring tools can be provided.
Description
Technical field
The utility model relates to a kind of teaching learning tool, particularly a kind of multifunctional compass.
Background technology
Compasses are a kind of circular drafting instrument that draws, traditional calipers function is comparatively single, after drawing circle, also need by ruler, radius or the diameter of circle to be implemented to measure, perhaps by ruler, compasses are positioned in the process of drawing, namely compasses can't be completed separately the circular pattern with dimensional requirement.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of need not just can implement the multifunctional compass of locating and measuring by other survey tool.
For achieving the above object, the utility model provides following technical scheme: a kind of multifunctional compass, include two straight-bars, two straight-bars are respectively scribing rod and backstay, backstay and scribing rod include respectively hinged end and working end, the hinged end of backstay and scribing rod is hinged, the place, working end of backstay is provided with pilot pin, the place, working end of scribing rod is provided with the line pen core, it is characterized in that: the hinged place of described backstay and scribing rod is provided with the folding straight plate that hangs by the elastic shrinkage part, and this straight plate is provided with scale.
Wherein, the elastic shrinkage part is the elasticity lanyard, and straight plate is comprised of at least two sections hinged plate bodys.
Adopt technique scheme, by hang folding straight plate by the elastic shrinkage part on compasses, and straight plate is provided with scale, make straight plate form the graduated ruler of tool, in use, only need the line pen core of the stretching compasses of straight plate and pilot pin place, determine that by the spacing of regulating backstay and scribing rod size both can, when need not to use, straight plate is pulled to the hinged end place of backstay and scribing rod by the pulling force of elastic shrinkage part with it, and directly plate is collapsible.After arranging like this, the size when need not just can realize the compasses drawing by the ruler of separately establishing, and also easy to carry.
The utility model further is set to: the line pen core at place, scribing rod working end is connected by dismountable knob with scribing rod, and the other end place of the pen core of ruling is provided with cutting cutter.
Adopt technique scheme, the setting of cutting cutter can be got off the circle that draws by cutting on paper.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is straight plate after folding in the utility model embodiment and the structural representation of elastic shrinkage part.
The specific embodiment
A kind of multifunctional compass as shown in Figure 1 and Figure 2, include two straight-bars, two straight-bars are respectively scribing rod 1 and backstay 2, backstay 2 includes respectively hinged end 3 and working end 4 with scribing rod 1, backstay 2 is hinged by hinge 5 with the hinged end 3 of scribing rod 1,4 places, working end of backstay 2 are provided with pilot pin 21,4 places, working end of scribing rod 1 are provided with line pen core 11, backstay 2 is provided with the hinged place of scribing rod 1 the folding straight plate 7 that hangs by elastic shrinkage part 6, and this straight plate 7 is provided with scale 71.In such scheme, by hang folding straight plate 7 by elastic shrinkage part 6 on compasses, and straight plate 7 is provided with scale 71, make straight plate 7 form the graduated rulers of tool, in use, only need the line pen core 11 of straight plate 7 stretching compasses and pilot pin place 21, determine that by the spacing of regulating backstay 2 and scribing rod 1 size both can, when need not to use, straight plate 7 is pulled to hinged end 3 places of backstay 2 and scribing rod 1 by the pulling force of elastic shrinkage part 6 with it, and directly plate 7 is collapsible.After arranging like this, the size when need not just can realize the compasses drawing by the ruler of separately establishing, and also easy to carry.
In the utility model embodiment, elastic shrinkage part 6 is the elasticity lanyard, and straight plate 7 is comprised of at least two sections hinged plate bodys 72; Need to prove, elastic shrinkage part 6 also can be rubber belt or the spring body with pulling force, is all feasible, and the hop count of straight plate 7 can be decided as required.
In the utility model embodiment, the line pen core 11 at 4 places, scribing rod 1 working end is connected by dismountable knob 8 with scribing rod 1, the other end place of line pen core 11 is provided with cutting cutter 12, and the setting of cutting cutter 12 can be got off the circle that draws by cutting on paper or cortex.
