Abstract
The invention provides multifunctional safety compasses. The multifunctional safety compasses comprise a pencil pipe, a rotating shaft, a compass leg a and a compass leg b. A guide slot c is formed along a vertical direction of the compass leg a, a compass needle is connected in the guide slot c through a slider f, the other guide slot d is formed along a vertical direction of the compass leg b, and a pencil lead holder is connected in the guide slot d through a slider g. An eraser is disposed in the pencil pipe which is hollow, and a cap is connected above the pencil pipe through threads. Safety in use of the compasses is guaranteed for users and while functionality of the compasses is improved.
Description
Technical field
The present invention relates to a kind of compasses, especially a kind of multifunctional safety compasses.
Background technology
In mathematics and drawing, compasses commonly used are drawn, and existing compasses are directly installed on the compasses pin on the compass foot on the market, the student is in use very dangerous, and carry also inconvenience, existing calipers function is all very single simultaneously, and other things such as rubber all will carry in addition.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of multifunctional safety compasses is provided, these compasses have guaranteed user's safety in use, have increased simultaneously functional.
For solving the problems of the technologies described above, technical scheme provided by the invention is:
A kind of multifunctional safety compasses, comprise nib, rotating shaft and compasses supporting leg a, b, vertical direction along compasses supporting leg a offers a gathering sill c, be connected with a compasses pin by slide block f in this gathering sill c, vertical direction along compasses supporting leg b offers another gathering sill d, is connected with a pen core folder by slide block g in this gathering sill d.
Gathering sill c is arranged on the middle below of compasses supporting leg a, and gathering sill d is arranged on the middle below of compasses supporting leg b.
The length of gathering sill c is less than the length of compasses supporting leg a 1/2nd, and the length of gathering sill d is less than the length of compasses supporting leg b 1/2nd.
Described nib is the hollow setting, is built-in with a rubber, and a block is threaded above the nib.
By above technical scheme, with respect to prior art, the present invention has following beneficial effect:
The present invention offers a gathering sill c along the vertical direction of compasses supporting leg a, be connected with a compasses pin by slide block in this gathering sill c, when not using the compasses pin, slide block is upwards pushed away, the compasses pin returns in the compasses supporting leg a, make things convenient for the user to carry this moment, and guaranteed that the user is not stung by syringe needle; Be built-in with a rubber in the position of nib, increased the functional of compasses.
Description of drawings
Fig. 1 is the overall structure of the present invention when using;
Fig. 2 is the overall structure of the present invention when not using;
Wherein: 1 is compass leg a, and 2 is compass leg b, and 3 is gathering sill c, and 4 is gathering sill d, and 5 is slide block f, and 6 is slide block g, and 7 is the compasses pin, and 8 are the pen core folder, and 9 are block, and 10 is rubber.
The specific embodiment
Accompanying drawing discloses the structural representation of preferred embodiment involved in the present invention without limitation; Explain technical scheme of the present invention below with reference to accompanying drawing.
Figure 1 shows that the overall structure when the present invention uses, when the user need to use compasses, promote slide block f downwards, compasses pin 7 stretches out from compass leg a inside, promotes slide block g downwards, and pen core folder 8 stretches out from compass leg b inside; Fig. 2 is the overall structure of the present invention when not using, and upwards promotes slide block f, and it is inner that compasses pin 7 is return compass leg a, upwards promotes slide block g, and it is inner that pen core folder 8 is return compass leg b, and this moment, compasses can make things convenient for the user to carry; Be built-in with a rubber 10 in the position of nib, be stamped block 9 on the rubber 10, made things convenient for the user to use rubber 10, also increased the functional of compasses simultaneously.
