Abstract

The utility model discloses a pair of novel practical compasses, which is characterized in that one end of a scale is perpendicularly connected to a supporting leg with an ejector at the bottom through a connecting part, a pen leg with a bottom end capable of clamping a brush is perpendicularly arranged at the other end of the scale through a vernier, and an observation hole and a fastening bolt are arranged on the vernier. Through the arrangement, when the pair of the practical compasses is used during circle drawing, the distance between the supporting leg and the pen leg, namely the radius of a circle to be drawn, can be determined by moving the vernier. The pair of novel practical compasses has a simple structure, and is convenient and practical.

Description

The novel practical compasses
Technical field
The utility model relates to a kind of teaching aid, is a kind of novel practical compasses specifically.
Background technology
Compasses are a kind of circle tools, and mostly existing compasses are to connect support with bipod, draw bowlder, need confirm that compasses need picture radius of circle size with ruler, the unit or the camber line that just can draw and meet size, and operation is trouble comparatively, makes troubles to teaching.
Summary of the invention
The purpose of the utility model is that a kind of novel practical compasses that need can on compasses, directly confirm the picture radius of circle are provided.
To achieve these goals; The utility model vertically is connected with the supporting leg of bottom band thimble through connector at an end of scale; The other end at scale vertically is provided with the leg that paintbrush can be clamped in the bottom through vernier, on said vernier, is provided with peep hole and fastening bolt.
Through above setting, the utility model can be confirmed the distance between a utility model supporting leg and the leg through moving cursor drawing bowlder, just needs the picture radius of a circle, accurately draws circle.The utility model is simple in structure, and is convenient and practical.
Description of drawings
Combine accompanying drawing that the utility model is further specified at present.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, scale, 2, supporting leg, 3, a leg, 4, vernier, 5, connector, 6, paintbrush, 7, thimble, 8, peep hole, 9, fastening bolt.
The specific embodiment
As shown in Figure 1; The utility model vertically is connected with the supporting leg 2 of bottom band thimble 7 through connector 5 at an end of scale 1; The other end at scale 1 vertically is provided with the leg 3 that paintbrush 6 can be clamped in the bottom through vernier 4, on said vernier 4, is provided with peep hole 8 and fastening bolt 9.Through above setting, the utility model is being drawn bowlder, can just need the picture radius of a circle through the distance between moving cursor 4 definite the utility model supporting legs 2 and the leg 3, accurately draws circle.
