The three angles of the set square body are 90 degrees, 30 degrees and 60 degrees respectively. A triangular hole is formed in the middle of the set square body. A circular hole is formed in the 60-degree-angle side and a chute is formed in the bevel edge; a cavity is formed in the chute and the protractor is fixedly connected with a rotary shaft; the ruler and the protractor are of an integrated structure; the pen sleeve assembly comprises a pen inserting hole, a fastening adjusting knob, a sliding block and an extending section; the fastening adjusting knob is connected with the pen inserting hole, one end of the pen inserting hole is connected with the extending section, and the extending section is connected with the sliding block; the sliding block is embedded in the cavity and used for moving in the chute. The combined type compass set square is reasonable in design and structure, convenient to use and capable of drawing arcs of different angles easily.
Description
Technical field
The utility model relates to educational aid field, especially a kind of Combined compasses set square.
Background technology
In the middle of daily study and work, be widely used drafting instrument, these drafting instruments mainly comprise set square, ruler, compasses and protractor.Traditional set square is all the set square of a special purpose, in study or teaching drawing course, often needs to be used in conjunction with other drafting instruments.While drawing the circular arc of special angle, need compasses and protractor to be used in conjunction with, speed is slow and process is loaded down with trivial details, and drawing efficiency is low, and thing is how not portable.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, provide a kind of Combined compasses set square, draw the enough easily circular arc of various angles of reasonable, the easy to use and prodigiosin of its project organization.
The utility model solves the technical scheme that its technical problem adopts: a kind of Combined compasses set square, comprise set square, protractor, ruler, fixed point round platform, pen cap assembly and bearing, three angles of described set square are 90 °, 30 ° and 60 °, centre is provided with tri-angle-holed, 60 ° of angle one sides are provided with circular hole, and hypotenuse is provided with chute; In described chute, be provided with cavity volume; Described protractor is fixedly connected with rotating shaft; Described ruler and protractor are integral structures; Described pen cap assembly comprises pen plughole, fastening adjustment knob, slide block and extension; Described fastening adjustment knob is connected with pen plughole, and one end of described pen plughole is connected with extension, and described extension is connected with slide block; Described slide block is embedded in cavity volume for moving in chute; Described bearing is to be embedded in circular hole, and the outer rolling circle of bearing is connected with circular hole secure fit, and the interior rolling ring of bearing is connected with rotating shaft secure fit; Described protractor is to be connected by bearing rotary with described set square.Described fixed point round platform is arranged on the position corresponding with rotating shaft, the protractor back side.
Further, two right-angle sides and the hypotenuse of described set square are provided with scale.
The beneficial effects of the utility model are: described a kind of Combined compasses set square, adopt the set square of this kind of design, combined the function of ruler, protractor, compasses on the architecture basics of traditional triangle plate, its rotating part adopts bearing to connect, picture circular arc is smooth and easy, draws arbitrarily various angle circular arcs.
