Description
Technical field
This utility model belongs to teaching aid technical field, particularly to a kind of Simple compasses.
Background technology
Existing compasses typically have independent two lower limb, and one is leg, and another draws circle.This knot
Structure is more firm, is suitable for life-time service.But, in teaching process, the rings such as some occasion is such as outdoor
Saving and consider for simplicity, this compasses volume is relatively big, not readily portable.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of simple circle
Rule, can meet the rounding demand in general teaching process, and be convenient for carrying.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of Simple compasses, including ruler body, one end of ruler body is spininess, passes through bearing pin at this end
One one end connecting the first bar, the other end of the first bar connects one end of the second bar by bearing pin two, and second
The other end of bar is provided with hold assembly.
Described ruler body, the first bar and the second bar are straight plate structure, and respective residing plane is the most parallel.
Described hold assembly is arranged on the lateral surface of the second bar by torsion spring, hold assembly has annular or
Person's semi-circular hole, the bar length direction of hole length direction and the second bar is consistent.
Compared with prior art, this utility model meets the rounding demand in general teaching process, and side
Portable belt.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is the end view of this utility model the second bar.
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings with embodiment.
As it is shown in figure 1, a kind of Simple compasses, including ruler body 1, one end of ruler body 1 is spininess,
Connecting one end of the first bar 3 at this end by bearing pin 1, the other end of the first bar 3 passes through bearing pin 24
Connecting one end of the second bar 5, the other end of the second bar 5 is provided with hold assembly 6.Wherein, ruler body 1,
First bar 3 and the second bar 5 are straight plate structure, and respective residing plane is the most parallel.
As in figure 2 it is shown, hold assembly 6 is arranged on the lateral surface of the second bar 5 by torsion spring, clamping part
Having annular or semi-circular hole on part 6, the bar length direction of hole length direction and the second bar 5 is consistent.
Use process of the present utility model is:
When using as common ruler, the first bar 3 and the second bar 5 are turned to residing for ruler body 1
In plane, now, owing to hold assembly 6 is positioned at the lateral surface of the second bar 5, the most do not affect as directly
Chi uses.When using as compasses, pull out the first bar 3 and the second bar 5, by chalk or other paint
Figure pen is arranged in hold assembly 6, can realize picture with the spine end of the second bar 5 for the center of circle and justify.
