Description
Technical field
The utility model relates to a kind of chi, particularly a kind of compasses chi.
Background technology
Ruler and compasses all are our the most frequently used drafting instruments, but these two kinds of drafting instruments separate, and are separate, carry not to be very convenient.All need install pen core when using compasses at every turn, also will unload pen core after finishing using, not so pen core ruptures easily.The center of circle pilot pin of common compasses is shifted easily, and not only the center of circle is not easy the location, and diameter of a circle also deviation can occur.Use common compasses to draw bowlder and at first will measure radius of a circle, and then draw circle according to the radius of measuring by ruler, complex steps, and make mistakes easily.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of simple, convenient ruler and the compasses chi of compasses and usefulness.
For solving the problems of the technologies described above, described compasses chi, comprise ruler, it is characterized in that being provided with slide rail in the middle of this ruler, be provided with coaster in a side of slide rail, the lower end of this coaster is provided with flexible automatically center of circle pin, the upper end of coaster is provided with button, the opposite side of slide rail is provided with coaster, and the lower end of this coaster is provided with automatic pen core, and the upper end of coaster is provided with button.Described button is a removable lining cap, is provided with rubber in the cap, unloads cap when using rubber as need and just can use, and is easy to operate.
On the ruler of described compasses chi, be provided with salient point respectively in 0 scale and full scale place, better fixed block, coaster is unlikely to skid off slide rail when operation.Because coaster is significantly less than the width of ruler, so can not influence the function of use of ruler because of the existence of coaster.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the utility model compasses chi.
Among the figure: 1. ruler, 2. slide rail, 3. coaster, 4. center of circle pin, 5. button, 6. coaster, 7. pen core, 8. button automatically.
The specific embodiment
As shown in Figure 1, a kind of compasses chi, comprise ruler 1, it is characterized in that being provided with slide rail 2 in the middle of this ruler, be provided with coaster 3 in a side of slide rail 2, the lower end of this coaster is provided with flexible automatically center of circle pin 4, the upper end of coaster 3 is provided with button 5, the opposite side of slide rail 2 is provided with coaster 6, and the lower end of this coaster 6 is provided with automatic pen core 7, and the upper end of coaster 6 is provided with button 8.When using compasses to draw, press the button 5, stretch out the fixedly center of circle of center of circle pin, press the button 8 again and promptly can stretch out pen core, regulate the distance of two coasters, just can draw, easy to use, draw accurately.
Described button 8 is a removable lining cap, is provided with rubber in the cap, unloads cap when using rubber as need and just can use, and is easy to operate.On the ruler 2 of described compasses chi, be provided with salient point respectively, better coaster be fixed between slide rail and be unlikely to skid off slide rail in 0 scale and full scale place.Because coaster is significantly less than the width of ruler, so can not influence the function of use of ruler because of the existence of coaster.
