Abstract
The utility model relates to a student ruler, which comprises a main ruler, wherein the inner side surface of the bottom part of the main ruler is provided with a main ruler disc which is siamesed with the main ruler. The main ruler disc is provided with a connecting hole of the main ruler. The center of a circle of the main ruler disc is a cross point of the inner side edge and the bottom edge of the main ruler. The student ruler also comprises an auxiliary ruler, wherein the inner side surface of the bottom part of the auxiliary ruler is provided with an auxiliary ruler disc which is siamesed with the auxiliary ruler. The auxiliary ruler disc is provided with scale lines of angles, and a connecting hole of the auxiliary ruler. The center of a circle of the auxiliary ruler disc is a cross point of the inner side edge and the bottom edge of the auxiliary ruler. The auxiliary ruler disc is arranged above the auxiliary ruler disc and is movably connected through a connecting shaft and a nut. The outer side surface of the main ruler is provided with a pencil clamp which is provided with a chute, and a bolt is positioned in the chute. The bolt is fixed on the outer side surface of the main ruler. The pencil clamp is glidingly connected through the bolt along the outer side surface of the main ruler. The bolt is used for locking tightly the pencil clamp. A row of circle drawing holes is arranged along the longitudinal direction of the main ruler. The utility model has the advantages of simple structure, and convenient and visual angle lines of drawing circles and figures.
Description
Technical field
The utility model relates to a kind of figure surveying and mapping tool, especially a kind of multi-functional student's chi.
Background technology
In the prior art, multi-functional student's chi generally is that ruler, set square, protractor simple combination are used together, draws the figure have certain angle and the round belt of drawing certain radius come inconvenience for the student, and also intuitive and convenient not during the angle of spirogram shape.
Summary of the invention
The purpose of this utility model provides a kind of picture circle and the convenient student's chi intuitively of picture shape angle line.
To achieve these goals, the utility model student chi comprises main scale, it is characterized in that: on the medial surface of main scale bottom, have one with the main scale disk of main scale disjunctor, main scale connecting hole, the center of circle of main scale disk are arranged is the inner side edge of main scale and the intersection point on base in design on the main scale disk; Other comprises a secondary chi, have on the medial surface of the bottom of secondary chi one with the secondary chi disk of secondary chi disjunctor, have the angle index line on the secondary chi disk, secondary chi connecting hole, the center of circle of secondary chi disk are arranged is the inner side edge of secondary chi and the intersection point on base in design on the secondary chi disk; Secondary chi disk be contained in the main scale disk above, flexibly connect by connecting axle, nut; The lateral surface of main scale is equipped with pencil holder, has chute on the pencil holder, and screw is positioned at chute, and screw is fixed on the lateral surface of main scale, pencil holder by screw along being slidingly connected the screw lock pencil holder on the lateral surface of main scale; Along design on the main scale longitudinal direction one row's picture circular hole is arranged.
The utility model can utilize main scale, secondary chi separately when using as ruler, or main scale, secondary chi are launched into 180 degree uses.When using, only need the corresponding respectively both sides of desiring angle measurement in main scale, secondary chi limit, read value from secondary chi then, promptly get and desire the angle measurement number of degrees by the angle index of main scale sideline correspondence as protractor.When drawing the angle, the reverse operating of doing aforesaid operations gets final product.
The utility model makes that this chi is simple in structure, is easy to carry owing to take said structure, and it is convenient directly perceived to draw circle and picture shape angle line, and scale numerical value more easily reads.
