Description

A kind of single armed white board compasses with a scale
Technical field
The utility model belongs to educational aid field, and particularly one is with graduated white board compasses.
Background technology
Compasses often need to use in our daily teaching process, compasses are very early while withstand on another side on blackboard by thimble to clip chalk, this traditional compasses are adapted at body of wall blackboard uses, along with the continuous progress of society, body of wall blackboard substantially steps down from the stage of history, the substitute is blank, blank is smooth, impetus is bad fixing, above-mentioned this traditional compasses just can not employ, in order to ensure that compasses can use on blank, we must make certain amendment to traditional compasses, Chinese patent literature CN201012594Y discloses a kind of white board compasses, comprise magnet, the collar, expansion link and draw-in groove, magnet is cylindrical structure, magnet is provided with the collar, the collar is flexibly connected with magnet, the collar and expansion link affixed, draw-in groove is provided with away from the end of the collar at expansion link, the compasses of this improvement can use on blank, but also there is certain defect, dish not with a scale on compasses, when needs are precisely drawn, these compasses just cannot have been accomplished, use inconvenience, moreover, expansion link is in use easily subjected to displacement deviation, normally uses and brings great inconvenience, reduce service efficiency to us.
The technical problems to be solved in the utility model is to provide a kind of Novel whiteboard compasses of drawing accurate, easy to use.
Utility model content
Draw not precisely for solving above-mentioned prior art, use the problems such as inconvenient, service efficiency is low, the utility model adopts following technical scheme:
The utility model provides a kind of single armed white board compasses with a scale, comprise holder, fixed bar, the collar, connecting rod, pen clip and paintbrush, described holder is fixed on external blank, described fixed bar is fixed on described holder, the described collar is movably arranged on described fixed bar, described connecting rod is fixedly connected with the collar, described connecting rod is provided with dial, described pen clip to be movably arranged on described connecting rod and can to move along connecting rod, and described paintbrush is fixedly clamped on described pen clip.
As to improvement of the present utility model, described holder is magnet.
As to further improvement of the utility model, described in be fixed on as vacuum cup.
The beneficial effects of the utility model are: on connecting rod, arrange dial, can draw required circle accurately, and one end is fixed one end and rotated, and use more convenient, service efficiency is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Refer to Fig. 1, a kind of single armed white board compasses with a scale, comprise holder 1, fixed bar 2, the collar 3, connecting rod 4, pen clip 5 and paintbrush 6, described holder 1 is fixed on external blank 7, holder 1 can select magnet or vacuum cup, as long as can fixed bar be fixed on blank, preferably vacuum cup is used as holder, described fixed bar 2 is fixed on described holder 1, the described collar 3 is movably arranged on described fixed bar 2, described connecting rod 4 is fixedly connected with the collar 3, described connecting rod 4 is provided with dial 41, described pen clip 5 to be movably arranged on described connecting rod 4 and can to move along connecting rod 4, described paintbrush 6 is fixedly clamped on described pen clip 5, during operation, pen clip 5 and paintbrush 6 are moved on the corresponding scale of dial 41 and fixes, paintbrush 6 dominated by hand also makes it rotate on blank 7, fixed bar 2 maintains static, the just connecting rod 4 of movement, ensure that the round size drawn is accurate by dial, and one end rotating manner is fixed in one end, ensure neither to there will be offset deviation in drawing processes, use more convenient, picture efficiency is higher, and traditional compasses are all not with a scale, the circle drawn is not accurate, and pole is easily subjected to displacement deviation when drawing, affect picture efficiency, use inconvenience, can be addressed this problem by above-mentioned improvement.
