Description
Technical field
The utility model relates to a kind of teaching aid, especially a kind of compasses for teaching.
Background technology
At present, often need teacher on blackboard, draw various figure in mathematical education process, wherein use many drawing tools to have compasses, compasses comprise two supporting legs, and the end of a supporting leg is provided with needle point, locate for the center of circle, another supporting leg is provided with pen, but because the needle point of compasses is relatively more sharp-pointed, little with the contact area of blackboard, easily skid during operation, cause mapping inaccurate, and when exerting oneself excessive, may blackboard surface be damaged, make troubles to teaching; In addition the chalk clamping device of compasses does not have a kind of clamper portable and easy to use in use, and changing the deficiencies in the prior art will at the enterprising Row sum-equal matrix of the structure of compasses.
Prior art can not meet the needs of people, and for making up prior art deficiency, the utility model aims to provide a kind of compasses for teaching.
For achieving the above object, the utility model by the following technical solutions: a kind of compasses for teaching, at least comprises chalk clamp gripping member, rotation regulation foot, connector, handle, swing handle, fixing regulation foot, sucker and bolt; Described chalk clamp gripping member is arranged on rotates regulation foot bottom, and is connected with rotation regulation foot; Described rotation regulation foot and fixing regulation pin top are rotationally connected by connector; Described swing handle is arranged on connector top, and is fixedly connected with connector; Described handle is connected with swing handle is vertical; Described sucker is connected with fixed gauge sole end by bolt.
As further technical scheme of the present utility model: described chalk clamp gripping member comprises thread groove, tailstock, chute, circular arc projection, slide bar and retainer; Described thread groove to be opened in retainer and to be threaded with rotation regulation foot; Described slide bar is inserted in tailstock, and slide bar two ends are inserted in chute; Described circular arc projection is arranged on retainer top inner side.
Preferred: described rotation regulation foot bottom offers the screw thread coordinated with thread groove; Described sucker is rotational structure by bolt and fixing regulation foot junction.
Compared with prior art, the beneficial effects of the utility model are: this compasses for teaching, by original chalk sleeve is improved, chalk more easily uses in clip, and convenient disassembly, in addition fixed gauge sole end adopts sucked type structure, such that overall entering shape, to draw bowlder more convenient, more stable.
Overall structure is simple, practical, easily manufactured, is easy to promote the use of.
