Description

A kind of plotter
Technical field:
The utility model is to belong to teaching aid.
Background technology:
The utensil that teacher uses when imparting knowledge to students drawing is the amplification version of common compasses; Common compasses only are fit to the plane mapping, and are unsuitable for drawing on blackboard; On blackboard, draw, often need to have measured length with rule earlier; Want fixedly both sides of both hands during drawing, apparatus is very big; Very inconvenient, also can increase error, and efficient is low.
The utility model content:
The utility model is exactly at the problems referred to above, provides a kind of and can directly measure length, plotter easy to use.
For achieving the above object, the utility model adopts following technical scheme, has the sucker of protractor above the utility model comprises, the screw rod on its structural feature sucker top is provided with ruler, is with the slide block with hole on the ruler, and ruler end is provided with block.
The beneficial effects of the utility model:
An end of the present utility model is provided with sucker, plays fixation, can directly measure scale, has so just reduced the step of prior tolerance scale; Be difficult for being fixed on the blackboard thereby solved former compasses articles for use needle point, chalk is had no progeny and is inconvenient to take out, and the compasses bipod is difficult for the technical problem of leveling.The sucker top also is provided with protractor, can measure required angle, can draw arc or angle.The utlity model has multiple use, improved the efficient of teaching and study greatly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The suction 8 that has protractor 5 above the utility model comprises, the screw rod 6 on sucker 8 tops is provided with ruler 4, is with the slide block 3 with hole 2 on the ruler 4, and ruler 4 ends are provided with block 1.
Also be provided with dial 7 on the screw rod 6 of sucker 8; Stir sucker 8 with dial 7 and rotate, can reach the angle of required ruler 4.
During use, chalk can be fixed in the hole 2, draw the fixedly center of circle of bowlder sucker 8, move the slide block 3 that is with chalk and select corresponding scale, rotate 360 ° and get final product.Throughput hornwork 5 selects the rotation of the respective corners number of degrees to get final product when drawing arc.Select the respective corners number of degrees when drawing the angle, move the slide block 3 that is with chalk afterwards and get final product.
