Abstract
The invention discloses a teaching compass, which comprises a ruler; wherein, one end of the ruler is provided with a turntable; a fixed device used for bonding with a writing plate is arranged on the turntable; the ruler is connected with the turntable by a rotating shaft and can carry out circular motion by taking the rotating shaft center as a circular point; a slide groove and a slide block are arranged on the ruler; the slide block is arranged in the slide of the groove and holes are arranged on the slide block for putting teaching pens. Compared with the traditional compass, the novel teaching compass has a completely different design proposal which has simple structure and a plurality of applications.
Description
Technical field
The present invention relates to educational aid, be specially educational compasses.
Background technology
Existing educational compasses generally comprises two mobilizable jibs, but uses and inconvenience.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of novel educational compasses is provided.
The present invention has adopted following technical proposals to solve above-mentioned technical problem:
A kind of educational compasses, comprise ruler, wherein, ruler one end is provided with rotating disk, and rotating disk is provided with the fixture that is used for the clipboard applying, and it can the rotating shaft center be that round dot is done the circumference rotation also that ruler is connected through rotating shaft with rotating disk, ruler is provided with chute and slide block, slide block is located in the chute, establishes the hole on the slide block, is used to place teaching pen.
Preferable, above-mentioned ruler is provided with scale.
Preferable, the fixture that can fit with clipboard on the above-mentioned rotating disk is sucker or magnet.
Preferable, be attached with deformable material around the hole on the above-mentioned slide block, can do suitably distortion with fixing teaching pen according to the size of built-in teaching pen such as chalk or water-color paintbrush.
When clipboard contains iron, magnet is set on the rotating disk, thereby with rotating disk fixing with clipboard on, lettering pen is inserted slide block, the diameter of the position adjustments circumference by adjusting slider, thereby realize the purpose of picture circle or circular arc.
When clipboard not during iron content, on the rotating disk sucker can be set, thereby with rotating disk fixing with clipboard on, realize the purpose of picture circle or circular arc.
Owing to be the ruler design, therefore also can be used as conventional ruler.
The present invention compares with traditional compasses, and design is different, simple in structure fully, and one-object-many-purposes.
