Description
Technical field
The utility model relates to realia technical field more particularly to a kind of rulers convenient for positioning.
Background technique
Existing compasses are two supporting legs, and chalk, the end of another supporting leg are installed in the end of one of supporting leg
As soon as portion is a pointed steel needle, if in the bad use of blackboard upper drawing circle in teaching, the reason is that the pointed steel needle on supporting leg
It is easy to skid on blackboard, the bad determination in the center of circle, but also blackboard can be damaged.The purposes of this compasses is also relatively simple.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of ruler convenient for positioning, the teaching special ruler
Rule effectively combine ruler and compasses, are easy to use, the compasses of two traditional supporting legs are changed to single leg and are fixed, and have and stablize
With safe and reliable feature.
To achieve the goals above, the utility model is achieved through the following technical solutions:
A kind of ruler convenient for positioning, including ruler 1 are provided with reel 12 above 1 plane one end of ruler, with around
1 end of ruler of 12 side of line wheel is provided with fixed disk 11, and 1 end of ruler is compasses module 4, and compasses module 4 includes and fixation
Be provided with rotatable rotating wheel 10 between disk 11, the limited mouth 9 of fixed function be installed on rotating wheel 10, limited mouth 9 with
Rotating wheel 10 is rotated, and the line of the reel 12 is connected after being fixed by limited mouth 9 with chalk bayonet 5.
The line wheel 8 of coiling is installed between the reel 12 and limited mouth 9.
1 side of ruler is provided with handle 2 and chalk storage box 3.
Be provided with handle 6 at the top of the reel 12,6 one end of handle by the fixed rotation of bearing block 13, the other end with
7 phase of the bayonet clamping at 12 top of reel is set.
The line wheel 8 and the angled fixation of reel 12 passes through fixed axis connection with ruler 1, is equipped at cooperation
Bearing.
The limited mouth 9 is equipped with bayonet, can step up the cotton rope passed through by rotary bayonet.
Described 5 one end of chalk bayonet is equipped with groove, and the other end is equipped with pintongs bayonet.
The utility model has the beneficial effects that
The utility model effectively combines ruler and compasses, is easy to use, the compasses of two traditional supporting legs are changed to
Single leg is fixed, and determines radius using cotton rope, limits picture radius of circle by device size, has stable and safe and reliable spy
Point.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Fig. 2 Fig. 3: a kind of ruler convenient for positioning, including support 1, it is provided with above 1 plane one end of ruler
Reel 12 is provided with fixed disk 11 with 1 end of ruler of 12 side of reel, and 1 end of ruler is compasses module 4, compasses mould
Block 4 includes that rotatable rotating wheel 10 is provided between fixed disk 11, and the limit of fixed function has been equipped on rotating wheel 10
Mouthfuls 9, limited mouth 9 is rotated with rotating wheel 10, the line of the reel 12 by limited mouth 9 it is fixed after with chalk bayonet 5
It is connected.
The line wheel 8 of coiling is installed between the reel 12 and limited mouth 9.
The line wheel 8 and the angled fixation of reel 12 passes through fixed axis connection with ruler 1, is equipped at cooperation
Bearing.
The limited mouth 9 is equipped with bayonet, can step up the cotton rope passed through by rotary bayonet.
The fixed disk 11 is to be made in ruler one end of soft material, fixed on blackboard convenient for compasses.
The reel 12 is set to one end of ruler 1, and with ruler 1 by axis connection, junction is equipped with bearing.
The ruler 1 is equipped with chamfering on one side, and scale is indicated on fillet surface.
1 side of ruler is provided with handle 2 and chalk storage box 3 as shown in Figure 1:.
As shown in Figure 4: described 5 one end of chalk bayonet is equipped with groove, and cord is facilitated to fix with chalk bayonet.The other end is set
There is pintongs bayonet, facilitates the fixation of chalk.
