Abstract
The utility model relates to a sucker type circle tool, which comprises a circle tool body. A rotating shaft is arranged at one end of the circle tool body, a sucker is connected to the rotating shaft, the circle tool is provided with graduation marks, and a chalk fixing portion is arranged along the graduation mark direction and comprises a plurality of chalk fixing holes. Therefore, when the sucker type circle tool is used for describing a circle, the circle of a corresponding radius can be descried according to the radius of the circle to be described by putting chalks into the corresponding chalk fixing holes, fixing the sucker to a chalkboard and rotating the circle tool body through the rotating shaft.
Description
Technical field
The utility model relates to a kind of cyclograph, relates in particular to a kind of sucked type cyclograph.
Background technology
The teacher generally uses compasses when the blackboard upper drawing circle, because the surperficial smoother of blackboard is easy in the process of drawing circle, make compasses landing from the blackboard, and the circle of drawing different radii to need to regulate the radius of compasses cumbersome.
The utility model content
The utility model is in the process of drawing circle, compasses landing from the blackboard easily, and draw the cumbersome deficiency of radius that the circle of different radii needs to regulate compasses, a kind of sucked type cyclograph is provided.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of sucked type cyclograph comprises the cyclograph body, one end of described cyclograph body is provided with rotating shaft, be connected with sucker in the described rotating shaft, has scale on the described cyclograph body, along having the chalk fixed part on the direction of described scale, described chalk fixed part comprises a plurality of chalk fixing holes.
The beneficial effects of the utility model are: use the utility model sucked type cyclograph to draw bowlder, according to drawing the radius of a circle size, chalk is put in the corresponding chalk fixing hole, again sucker is fixed on the blackboard, and by rotating shaft rotation cyclograph body, can draw by the chalk in the chalk fixing hole has the circle of relevant radii.
Description of drawings
Fig. 1 is the front view of the utility model sucked type cyclograph;
Fig. 2 is the vertical view of the utility model sucked type cyclograph.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
Fig. 1 is the front view of the utility model sucked type cyclograph, and Fig. 2 is the vertical view of the utility model sucked type cyclograph.Shown in Fig. 1 and 2, described sucked type cyclograph comprises cyclograph body 2, one end of described cyclograph body 2 is provided with rotating shaft, be connected with sucker 1 in the described rotating shaft, has scale 3 on the described cyclograph body 2, along having chalk fixed part 4 on the direction of described scale, described chalk fixed part 4 comprises a plurality of chalk fixing holes 5.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
