Abstract

The utility model discloses novel compasses. The novel compasses are characterized in that: a drawing support rod is movably connected with one end of a fixing support rod through a spindle; the middle part of the drawing support rod is movably connected with a strut bar through the spindle; the support rod is provided with a plurality of fixing holes; the middle part of the fixing support rod is provided with fixing pins which are matched with the fixing holes; a chalk is arranged at the lower end of the drawing support rod through a locking screw; and a fixing foot is arranged at the lower end of the fixing support rod. By the structure, during drawing, the size of the circle can be directly set according to the radius of the circle which is required to be drawn, and the compasses are fixed to ensure that the circle is convenient to draw and the drawing of the circle is easy to operate. The novel compasses have a novel design and practicability.

Description

Novel bow compass
Technical field
The utility model relates to a kind of novel bow compass.
Background technology
In daily teaching and propaganda work, people need make the picture circle on vertical planes such as blackboard, wall, glass, this needs compasses, compasses commonly used comprise Gauge for the centre of a circle pin and mapping rule pin, usually be subjected to certain limitation making the picture bowlder, when drawing, tend to bad fixing than great circle, it is inaccurate to draw circle, and can relatively require great effort.
Summary of the invention
The purpose of this utility model is that a kind of easy to use, round novel bow compass accurately of picture is provided.
To achieve these goals, drawing pole of the present utility model and fixedly an end of pole be movably linked together by rotating shaft, middle part drawing pole is connected with support bar by the rotating shaft activity, on described support bar, be provided with a plurality of fixing holes, be provided with the steady pin that matches with fixing hole in the fixing middle part of pole, the lower end that chalk is located at drawing pole by fastening bolt, fixing feet is located at the fixedly lower end of pole.
By above setting, the utility model is being made the picture bowlder, can directly set the size of circle according to the size of need picture radius of circle, fixes, and makes the picture circle become convenient and easy to operate, and the utility model is novel, has practicality.
Description of drawings
Now the utility model is described in further detail in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, drawing pole 2, fixedly pole 3, support bar 4, fixing hole 5, steady pin 6, chalk 7, fixing feet
The specific embodiment
As shown in Figure 1, drawing pole 1 of the present utility model and fixedly an end of pole 2 be movably linked together by rotating shaft, middle part drawing pole 1 is connected with support bar 3 by the rotating shaft activity, on described support bar 3, be provided with a plurality of fixing holes 4, be provided with the steady pin 5 that matches with fixing hole 4 in the fixing middle part of pole 2, the lower end that chalk 6 is located at drawing pole 1 by fastening bolt, fixing feet 7 is located at the fixedly lower end of pole 2.By above setting, can determine the size of picture radius of circle by selecting fixing hole 4 and the length that steady pin 5 cooperates, and not yielding, make the picture circle become convenient and easy to operate.
