Abstract

The utility model relates to a multi-functional scriber which comprises a scale and is characterized in that one end of the scale is provided with a rotating shaft, the bottom end of the rotating shaft is provided with a sucker, a slider is arranged on the scale in a sliding manner, and a chalk clamp device is arranged at the bottom of the slider. After the technical scheme is adopted, one end of the scriber can be easily fixed on a blackboard to draw a circle, a straight line can be drawn through the pushing of the slider, and an angle can be drawn through the rotating of the scale and the pushing of the slider. The multi-functional scriber has the advantages of ingenious design and convenience for use and achieves the purpose of having multiple functions.

Description

Multi-functional setting-out device
Technical field
The utility model relates to a kind of teaching aid, relates to a kind of multi-functional setting-out device particularly.
Background technology
In teaching processes such as mathematics, often need arrive setting-out on blackboard, as draw circle, picture triangle or other figure; When drawing these figures, need use different line tools, draw circle like needs with compasses; Draw straight line or triangle with set square,, particularly drawing bowlder with compasses because the plate face of blackboard is harder; The stiff end of compasses is generally nail or draw point, is not easy to fix, so it is just relatively difficult to draw fenestra.In addition, no matter be compasses or set square, picture circle that can only be independent is straight line or triangle perhaps, and can not reach the purpose of one-object-many-purposes.
The utility model content
The problem that the utility model will solve is to above problem, and a kind of multi-functional setting-out device of easy to use, diverse in function is provided.
For addressing the above problem, the technical scheme that the utility model adopted is:
Multi-functional setting-out device comprises scale, it is characterized in that: an end of said scale is provided with rotating shaft, and the bottom of rotating shaft is provided with sucker, is slidingly fitted with slide block on the scale, and the bottom of slide block is provided with the chalk clamping device.
As a kind of prioritization scheme:
Said chalk clamping device comprises the pen stand that is fixedly connected with slide block, accompanies chalk in the pen stand.
As a kind of prioritization scheme:
The top of said slide block is provided with holding screw.
As a kind of prioritization scheme:
Said scale is provided with the retaining head away from an end of rotating shaft.
The utility model is taked above technical scheme, has the following advantages: 1, an end can very easily be fixed on the blackboard upper drawing circle; 2, promote slide block and can draw straight line; 3, rotary scale and promotion slide block can be drawn the angle.The utility model design is ingenious, easy to use, has reached the purpose of one-object-many-purposes.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Accompanying drawing 1 is the structural representation of multi-functional setting-out device among the utility model embodiment;
Accompanying drawing 2 is the side-looking structural representation of multi-functional setting-out device.
Among the figure: the 1-scale; The 2-rotating shaft; The 3-sucker; The 4-slide block; The 5-holding screw; 6-keeps off head; The 7-pen stand.
The specific embodiment
Embodiment: as depicted in figs. 1 and 2, multi-functional setting-out device comprises scale 1, and an end of said scale 1 is provided with rotating shaft 2, and the bottom of rotating shaft 2 is provided with sucker 3, is slidingly fitted with slide block 4 on the scale 1, and the bottom of slide block 4 is provided with the chalk clamping device.
Said chalk clamping device comprises the pen stand 7 that is fixedly connected with slide block 4, accompanies chalk 8 in the pen stand 7.
The top of said slide block 4 is provided with holding screw 5.
Said scale 1 is provided with retaining 6 away from an end of rotating shaft 2.
During use, sucker 3 is fixed on the blackboard, unclamps holding screw 5, the position of adjustment slide block 4, the holding screw 5 of screwing, rotary scale 1 is drawn circle, through the distance of adjustment slide block 4, the concentric circles of the different-diameter that can draw; Draw straight line if desired, can unclamp holding screw 5, slide block 4 is slided along scale 1 get final product, draw the angle if desired, can be after finishing straight line, rotary scale 1 is drawn one again, forms the angle.Design ingenious, easy to use, diverse in function.
