Abstract

The utility model relates to novel compasses, comprising a connection bracket and a pen sleeve. The connection bracket consists of an inner bushing and an outer bushing, one end the inner bushing and one end of the outer bushing are connected by a shaft, the inner bushing and the outer bushing are provided with insertion holes, and bolts are externally arranged for fixing; the other end of the inner bushing and the other end of the outer bushing are fixedly connected with the pen sleeve, and the pen sleeve is connected with a pen body in an inserting manner. When the novel compasses are stored and carried, the pen can be taken down, the connection bracket is shortened to the shortest state, thereby reducing the volume of small compasses to store conveniently; when the novel compasses are used for drawing a circle, the length of the bushings can be adjusted according to the diameter of the circle, and the pen is inserted in the pen sleeve so that a circle can be drawn conveniently. The utility model has the advantages of simple structure, convenient use, reasonable design and the like, and effectively solves the problem that the storage and the carrying of the traditional compasses are not convenient.

Description

New-type compasses

Technical field the utility model relates to a kind of drawing appliance, especially a kind of new-type compasses of conveniently depositing.

The background technology compasses are one of main tool of drawing usefulness, but the deficiency that existing compasses exist is: relatively occupy the space, deposit and carry inconvenience.

The summary of the invention the purpose of this utility model has overcome above-mentioned said deficiency, and a kind of new-type compasses are provided, and deposits and carry inconvenient problem to solve existing compasses.

For achieving the above object, the new-type compasses of the utility model comprise the link and the pen cap, and link is made up of internal and external casing, and the connection of an end axle of internal and external casing, and establish jack on internal and external casing, and the peripheral hardware bolt is fixed; At the affixed pen cap of the other end of internal and external casing, and in pen cap interpolation type connection handwriting.

After adopting said structure, when depositing and carrying, pen can be taken off, link is contracted to the shortest, can reduce the volume of compasses, so that deposit; When drawing circle, can adjust the length of sleeve pipe, penholder is placed in the pen cap, can be convenient to the picture circle according to diameter of a circle.

The utility model has the advantages that: simple in structure, easy to use, structure has rationally solved existing compasses effectively and has deposited and carried inconvenient problem.

Description of drawings Fig. 1 is the overall structure schematic diagram of the new-type compasses of the utility model.

The specific embodiment as shown in Figure 1, the new-type compasses of the utility model comprise the link 1 and the pen cap 2, link 1 is made up of internal and external casing, and an end axle of internal and external casing connects, and establishes jack 3 on internal and external casing, peripheral hardware bolt 4 is fixed; At the affixed pen cap 2 of the other end of internal and external casing, and in the pen cap 2 interpolation types connection handwriting 5.
