Abstract
The utility model relates to a learning tool, in particular to modified compasses. The modified compasses comprise a dividing ruler. The modified compasses are characterized in that a fixed original point is arranged at one end of the dividing ruler, a moving paining point which is fixed through an adjustable bolt is further arranged on the dividing ruler, and a telescopic ruler is arranged in the dividing ruler. Therefore, the modified compasses have the advantages of being simple in structure, capable of adjusting the radius of a drawn circle according to needs and broadening the extension range and the application range of circle drawing, convenient to use and practical.
Description
(1) technical field
The utility model relates to a kind of schooling apparatus, particularly a kind of improvement compasses.
(2) background technology
Compasses commonly used are that two movable leg are formed, a fixed origin, and one is opened rotation picture circle.The circle of wanting divider calipers to decide radius or diameter needs the cooperation of rule, draws after measuring with compasses earlier again, and is the size that the length of two legs determines the picture circle, and often size can not be general, little is used for self-study, big is used for teacher's demonstration.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, provide a kind of simple in structure, easily transfer radius, convenient and practical improvement compasses.
The utility model is achieved by the following technical solution:
A kind of improvement compasses comprise rule, it is characterized in that: rule one end is provided with fixed origin, also is provided with on the rule with the fixing mobile picture point of adjustable bolt.
Improvement compasses of the present utility model is characterized in that: be provided with shrinkage-rule in the rule.
Therefore, the beneficial effects of the utility model are: these improvement compasses, and simple in structure, can adjust the picture radius of circle as required, flexible yardstick and the range of application expansion of drawing circle, convenient and practical.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model.
Among the figure, 1 rule, 2 fixed origin, 3 bolts, 4 move picture point, 5 shrinkage-rules.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises rule 1, it is characterized in that: rule 1 one ends are provided with fixed origin 2, also are provided with the mobile picture point of fixing with adjustable bolt 34 on the rule 1; Be provided with shrinkage-rule 5 in the rule 1.
Adopt improvement compasses of the present utility model, draw bowlder and pin the fixed origin 2 of rule 1 one ends, determine radius at rule 1 as required, drawing bowlder is fixed on adjustable set bolt 3 on the rule 1, be the center of circle with fixed origin 2,3 mobile picture points 4 of rotating bolt satisfactory circle that just can draw, when length requirement is too big, shrinkage-rule 5 can be extracted out, to increase radius of a circle, mobile picture point 4 is provided with draw-in groove, can fix multiple paintbrush, as pencil, chalk etc., to adapt to different user demands.Therefore, the beneficial effects of the utility model are: these improvement compasses, and simple in structure, can adjust the picture radius of circle as required, flexible yardstick and the range of application expansion of drawing circle, convenient and practical.
Claims (2)
1. improvement compasses comprise rule (1), and it is characterized in that: rule (1) one end is provided with fixed origin (2), also are provided with on the rule (1) with the fixing mobile picture point (4) of adjustable bolt (3).
2. improvement compasses according to claim 1 is characterized in that: be provided with shrinkage-rule (5) in the rule (1).
