Description

A kind of multi-functional square
Technical field
The utility model relates to square.
Background technology
For students in middle and primary schools and Graphing of Engineering person, the frequency of utilization of square is higher, but present square generally is to be used for picture straight line or wave or measure length, and in common drawing, picture straight line, picture circular arc often can be run into, and this just needs the designer to prepare many cover drawing tools, like this, not only carry inconvenience, and, also bad management.
Summary of the invention
The purpose of this utility model provides a kind of multi-functional square, and multi-functional square of the present utility model can not only be drawn straight line, and can draw circle.
For achieving the above object, a kind of multi-functional square comprises blade; Blade is provided with a chute, and that slides on the chute is provided with rider, and an end that is positioned at chute on the blade is provided with the initial point hole.
The utility model has the advantages that: owing to be provided with rider and initial point hole, two pens be inserted into get final product picture circle or circular arc on initial point hole and the rider, can also draw straight line or wave with blade simultaneously, function is many, and purposes is wide.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
Square as shown in Figure 1, comprise blade 1, the top edge of blade 1 has the scale 11 of picture straight line, has chute 2 on the blade 1, be provided with the rider that in chute, to slide in the chute 2, described rider comprises the screw 5 with a central shaft hole 6 and is located at nut 4 on the screw that when locking nut 4, rider is fixed on the somewhere of chute, when unclamping nut 4, rider can be in chute motion arbitrarily, an end that is positioned at chute on blade 1 is provided with initial point hole 3, is provided with scale 7 at the side of chute.
When needs picture straight line or when measuring length, directly adopt the top edge and the scale 11 of blade to get final product, when needs picture circle or circular arc, two pens are inserted into central shaft hole 6 on initial point hole 3 and the rider, and the position in chute according to circular arc or radius of a circle size adjustment rider makes the pen in initial point hole motionless, the rotation blade gets final product, therefore, square of the present utility model both can have been drawn straight line, measure length, can also draw circle.
