Description
Technical field
The utility model relates to a kind of schooling apparatus, and especially one carries scale, can be from the compasses of main regulation.
Background technology
Compasses are that it is one of indispensable instrument during we handle official business, learn for the instrument of picture circle and circular arc.It is made up of a hinge of two parts connection, and the connecting portion in the middle of it can adjust.In life; when common compasses construction, need use chi tool measuring radius, in the situation that there is no chi tool, the figure of making standard be had to significant limitation; in more situation, be to make figure; meanwhile, because the connecting portion of compasses is hinge, after the long-time use of compasses; hinge place is easily loosening; in the time of graphing, usually there will be the problem of dislocation, make troubles to Plot Work person.
Utility model content
For the above, the purpose of this utility model is to provide a kind of compasses, and it can be dismantled with assembled, can adapt to different planes, has effectively solved the problems referred to above.
In order to realize the technical scheme that the purpose of this utility model adopts be:
A kind of compasses, comprise backstay, chi tool device, mobile device and a tool, and chi tool device is made up of sleeve and shaft, and both link together, and jacket casing is combined on backstay, and the stack shell of sleeve is provided with screwed hole a supporting bolt; Shaft is provided with groove, and on shaft, goes back fit and mobile device, and mobile device connects the tool of beginning to write.
In some embodiments, backstay upper end is provided with Anti-slip handle, and lower end is provided with pilot pin, and being centered close on same straight line of pilot pin and backstay, thus, facilitates backstay location and rotation backstay.
In some embodiments, chi tool device side end face is provided with scale, and thus, convenient adjustment made radius of graph, and the other end of chi tool device is also provided with limiting plate, thus, can prevent that mobile device from departing from shaft.
In some embodiments, the left and right end of mobile device is provided with the through hole running through, and thus, through hole passes for shaft, and the upper and lower side of mobile device is provided with the through hole running through, and thus, through hole is used for placing a tool.
In some embodiments, the through hole of mobile device upper end is provided with the collar, and the collar is provided with screwed hole a supporting bolt, thus, can change the fixed position of a tool.
In some embodiments, tool is pencil or propelling pencil, in the time that a tool is positioned at the through hole of mobile device upper and lower side, its center line is vertical with the center line of shaft groove, simultaneously, the center line of shaft groove is vertical with the center line of backstay, thus, is convenient to pilot pin and nib at grade.
All parts of the present utility model combines, not only can be by regulating mobile device to choose radius of a circle, and by the sleeve of adjustable ruler tool device, can change the height of a tool, can adapt to the drafting of high bottom surface, no longer only, only limit in one plane map, in contrast to traditional compasses, it is more practical.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 has schematically shown the structure of the compasses of a kind of embodiment of the utility model.
As shown in Figure 1, a kind of compasses, comprise backstay, chi tool device, mobile device and a tool, and backstay upper end is provided with Anti-slip handle, and lower end is provided with pilot pin, and being centered close on same straight line of pilot pin and backstay; Chi tool device is made up of sleeve and shaft, and jacket casing is combined on backstay, between the two can relative sliding, and the stack shell of sleeve is provided with screwed hole a supporting bolt; Shaft is fixed on and on sleeve and on shaft, is provided with groove; The left and right end of mobile device is provided with the through hole running through, the through hole of left and right end is linked on shaft, the upper and lower side of mobile device is provided with the through hole running through, and the bunghole of upper and lower side passes for a tool, and a tool is pencil or propelling pencil, in the time that a tool is positioned at the through hole of mobile device upper and lower side, its center line is vertical with the center line of shaft groove, and meanwhile, the center line of shaft groove is vertical with the center line of backstay, thus, be convenient to pilot pin and nib at grade.
As shown in Figure 2, chi tool device side end face is provided with scale (numerical value arranges voluntarily in the time producing), the convenient radius of adjusting while mapping, and the other end of chi tool device is also provided with limiting plate, thus, can prevent that mobile device from departing from shaft.
As shown in Figure 3, the front end face of mobile device is provided with screwed hole a supporting bolt, by regulating the degree of tightness of screw thread, can impel mobile device move and fix.
When the utility model uses, jacket casing is combined on backstay, choose according to demand suitable position, screw subsequently the bolt on sleeve, increase the frictional force of itself and backstay, thereby chi tool device is fixed, again a tool is placed in mobile device, bolt by the collar is fixed a tool (principle is with the bolt on sleeve), the mobile device that finally slides is to suitable distance, and by the bolt on mobile device, mobile device is fixed on to (principle is with the bolt on sleeve) on shaft, just can graphing after pilot pin is fixed.
These are only embodiments more of the present utility model, to those skilled in the art, not departing under the prerequisite of the utility model creation design, also can carry out some distortion and improvement, these all belong to the utility model protection domain.
