Abstract

The utility model relates to a novel drawing compass which belongs to a drawing instrument and overcomes the disadvantages that exist in other instruments. The novel drawing compass has the structural relationship that a handle is fixed on a bracket, a needle leg is connected on the bracket by a fixed shaft, a pencil leg is connected on the bracket by the fixed shaft, a needle leg pull rod and a pencil leg pull rod are connected on the bracket by the fixed shaft, a needle leg rotation rod is connected on the needle leg by the fixed shaft, the needle leg pull rod is connected on the needle leg rotation rod by the fixed shaft, a pencil leg rotation rod is connected on the pencil leg by the fixed shaft, the pencil leg pull rod is connected on the pencil leg rotation rod by the fixed shaft, a drawing needle installation hole and a drawing needle hold-down screw are arranged on the needle leg rotation rod and a paintbrush installation hole and a paintbrush hold-down screw are arranged on the pencil leg rotation rod; the variable-angle compass has the advantages of simple structure, convenient use, high drawing precision, time conservation and labor conservation.

Description

Novel drawing compass

One, technical field:

The utility model relates to a kind of drawing appliance, especially novel drawing compass.

Two, background technology:

Compasses in the drafting instrument are varied at present, but ubiquity the problem of angle automatically, influences cartographic accuracy, incur loss through delay the drawing time.

Three, summary of the invention:

The purpose of this utility model provides a kind of easy to use, the cartographic accuracy height, save time, the novel drawing compass in labour-saving, it has overcome the shortcoming that other utensil exists, the purpose of this utility model is to realize like this, it is by handle, support, fixed axis, fixed axis, stitch, the stitch pull bar, fixed axis, fixed axis, the stitch swingle, draw the pin housing pin, fixed axis, pin, pin pull bar, fixed axis, fixed axis, the paintbrush installing hole, the paintbrush housing pin, draw the pin installing hole, pin swingle interconnects and forms, handle is fixed on the support, stitch is connected on the support by fixed axis, pin is connected on the support by fixed axis, a stitch pull bar and a pin pull bar are connected on the support by fixed axis, the stitch swingle is connected on the stitch by fixed axis, the stitch pull bar is connected on the stitch swingle by fixed axis, pin swingle is connected on the pin by fixed axis, pin pull bar is connected on the pin swingle by fixed axis, the stitch swingle is provided with picture pin installing hole and draws the pin housing pin, and a pin swingle is provided with paintbrush installing hole and paintbrush housing pin.

The pen that in use can reach the pin of stitch and a pin is all the time perpendicular to the purpose on picture plane,

During work, parallel principle and linkage characteristic according to parallelogram, pull bar driven rotary bar rotated when pin and stitch drew back, the paintbrush that makes the pin of stitch and a pin is all the time perpendicular to the picture plane, these angle compasses are simple in structure, easy to use, the cartographic accuracy height saves time, laborsaving.

Four, description of drawings:

1, handle 2, support 3, fixed axis 4, fixed axis 5, stitch 6, stitch pull bar 7, fixed axis 8, fixed axis 9, stitch swingle 10, picture pin housing pin 11, fixed axis 12, a pin 13, a pin pull bar 14, fixed axis 15, fixed axis 16, paintbrush installing hole 17, paintbrush housing pin 18, picture pin installing hole 19, a pin swingle

Five, the specific embodiment:

In Fig. 1: handle 1 is fixed on the support 2, stitch 5 is connected on the support 2 by fixed axis 3, pin 12 is connected on the support 2 by fixed axis 11, a stitch pull bar 6 and a pin pull bar 13 are connected on the support 2 by fixed axis 4, stitch swingle 9 is connected on the stitch 5 by fixed axis 7, stitch pull bar 6 is connected on the stitch swingle 9 by fixed axis 8, pin swingle 19 is connected on the pin 12 by fixed axis 14, pin pull bar 13 is connected on the pin swingle 19 by fixed axis 15, stitch swingle 9 is provided with picture pin installing hole 18 and draws pin housing pin 10, and a pin swingle 19 is provided with paintbrush installing hole 16 and paintbrush housing pin 17.
