Abstract

The utility model relates to eight-purpose compasses for students. A compass bar of the compasses and a graduated disc on the compass bar are provided with graduations. The utility model has the functions of a straightedge, a scale, a set-square and a protractor. A compass leg of the compasses is provided with pencil compasses, ink-dipping compasses and needle compasses which can be changed for use. A handle of the compasses is hollow structured and is provided with an eraser used for error correction of the pencil compasses. Integrated with the functions of various compasses, the utility model has the advantages of low cost, complete functions, firm and durability, flexible operation, convenient carrying, etc., and is the favorable tool for student learning.

Description

Eight-purpose compasses for students

The utility model relates to a kind of student garden rule of school supply and stationery.

In school supply and stationery, student garden rule are student's indispensable stationery, and therefore, various students garden rule are used and given birth to, and for example: commercially available dual-purpose, three usefulness student gardens rule have plumbous rule, dip in water rule, purposes such as divider, and still, the function of these student garden rule is less, if To be improved.

The purpose of this utility model is that the function of the various students of collection garden rule is an one, provides a kind of simple and easy, convenient, and more attains perfect student garden rule.

The utility model is to realize above-mentioned purpose like this: the solid handle transformation of the way of pass student garden rule is the hollow handle structure and loads onto rubber; Scale garden at gauge bar and gauge bar is marked with ruler, engineer's scale, set square, the scale of protractor; Load onto the convertible lead rule that are used in rule foot position, dip in water rule and divider, thereby made it to reach the function of a thing eight usefulness.

The eight usefulness student gardens rule of adopting the utility model to provide, available engineering plastics manufacturing, cost is low, and function is complete, and firm and durable is used flexibly, and is easy to carry.

Be specific embodiment of the utility model below:

Figure one is the overall pattern of eight usefulness student gardens rule;

Figure two is the rearview and the cutaway view of eight usefulness student gardens rule;

Eight usefulness student gardens rule are on the basis of pass student garden rule, to its solid handle part, and gauge bar scale position, rule pin conversion position, the novel student garden of improving, combining rule.

It with the solid handle of pass student garden rule change system into can setting-in rubber (1) hollow handle (2), and hollow handle (2) is connected rotation with gauge bar (4) (5) by rotating shaft (3), gauge bar (4) (5) is scale garden shape and trapezoidal, be carved with the scale of ruler, engineer's scale, set square, protractor on the plane of its gauge bar (4), clamping bolt (7) and the garden nut (9) of rule underfooting about leading to will be convertible dip in water rule (6) and divider lead and advise (8) and fix.

Garden rule gauge bars (4) (5) stretch can make ruler, engineer's scale.Summit with the open-work centrally aligned institute angulation of rotating shaft (3) transfers to the angle that matches with triangle with gauge bar (4) (5) then, can read angle value, makes protractor and uses.Draw the sole sideline earlier, with the open-work centrally aligned sole sideline end points of rotating shaft (3), measure required angle again, when being drawn as hypotenuse, can making set square and use.Measure and finish the central point and the radius point in garden earlier, fork gauge bar (4) (5), the clamping bolt (7) of rule pin and garden nut (9) can dip in the usefulness of water rule, divider and plumbous rule by using loosening and fixedly dipping in water rule (6) and the plumbous rule of divider (8).When plumbous programming line drawing is staggered the time, the correction of the hollow handle (2) of band rubber (1) can being touched the pillow.

Claims

1, a kind of student garden rule, it is characterized in that: the scale garden of gauge bar and gauge bar is marked with scale, and convertible plumbous rule are equipped with the position in rule foot, dip in water rule and divider.

2, student according to claim 1 garden rule is characterized in that: the handle of garden rule is hollow-core construction and rubber is housed.
