The beneficial effects of the utility model are：
A kind of Geometric figure drawing instrument of the utility model passes through ruler, compasses, protractor, camber line drawing ruler, set square etc.
Drawing instrument is all concentrated in together, it is achieved thereby that the situation of one-object-many-purposes, it is to avoid is left behind in study and work and is painted
Figure work instrument and the situation that occurs being normally carried out.
Description of the drawings
Fig. 1 is a kind of structural representation of Geometric figure drawing instrument described in the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of Geometric figure drawing instrument of the utility model, including square box 1, fixed ruler 3, turns chi 6 and slide block
7, square box 1 be internally provided with circular hole 2, the circle centre position of circular hole 2 is provided with fixed disc 4, fixed disc 4 pass through two fixations
The inwall of chi 3 and circular hole 2 is fixed, and two fixed rulers 3 are located at same horizontal line, and 2 even partition of circular hole is two semicircles, and two
The individual chi 6 that turns is separately positioned in two semicircles, and the inner for turning chi 6 is rotatably connected with fixed disc 4 by rotating shaft 9, fixed ruler 3
With turn the groove 5 that is provided with chi 6 along its axis direction, the outer of square box 1, the outer of circular hole 2, fixed ruler 3 and turn chi 6
On be provided with graduation mark, the length of fixed ruler 3 is equal to the radius of circular hole 2, turns the radius of the length less than circular hole 2 of chi 6, groove
5 a diameter of 1mm ~ 2mm, fixed ruler 3 and the width for turning chi 6 are 3mm ~ 5mm, and two the inners for turning chi 6 are justified with fixing respectively
Two sides of disk 4 are rotatably connected, and the circular place of fixed disc 4 is provided with through hole 10, and a diameter of 4mm of fixed disc 4 ~
6mm, a diameter of 1mm ~ 2mm of through hole 10, the outer end for turning chi 6 are provided with triangle dial plate 9, the center line of triangle dial plate 9 with turn
The center superposition of chi 6, slide block 7 are arranged on and turn on chi 6, and can slide along chi 6 is turned or fixing, are provided with a hole on slide block 7.
A kind of operation principle of Geometric figure drawing instrument of the utility model is as follows：
Ruler：Four sides of rectangle frame are used as ruler, the graduation mark on outer rectangular frame edge is distance scale line；
Compasses：The through hole 10 of fixed disc 4 is positioned at the circle centre position of the circle for needing drawing, then according to the half of drawing circle
Position of the footpath adjusting slider 7 on chi 6 is turned, and be fixed（Fixed form can fasten the upper and lower plates of slide block 7 for screw；Withhold
