Abstract

The utility model relates to the innovation of a pair of traditional compasses which is designed for solving the problems of complicated varieties and structure, functional defect, etc. of the existing drawing instruments. The multipurpose compasses with a sliding rod mainly adopts the purpose-made 'sliding rod' as a supporting leg, and a ' pen clamp' is used for combining the 'sliding rod' with a pen, and the size of a radius can be adjusted by changing the position of the ' pen clamp' in a 'sliding rod slot ' and changing the included angle of the ' pen clamp' and the 'sliding rod'. Consequently, circular arcs with desired colors and sizes can be drawn. The utility model can greatly eke out the shortages of a pair of common compasses, simplify the complexity of the drawing instrument and provide a better and more practical tool for drawing, and has the advantages of natural resources saving, etc.

Description

Many with litter compasses device

The utility model belongs to the innovation to tradition " compasses ".

" compasses " are one of the most common, topmost drawing instrument, known by common people, just because of this, its structure like fixed for: but enough make in conjunction with two legs of opening and closing at the top.And set out thus " plotter " made is numerous and diverse especially to the utmost, not only uses inconvenience, and has many defectives.As: the institute's circular arc of painting look is difficult to hope; Center of circle leg easily slides; " the plotter cost is in down difficult, costs an arm and a leg etc.Tracing it to its cause, mainly is the constraint that is subjected to the conventional construction principle, and complicated means go to solve a simple problem of using extremely to the greatest extent! Just think: a center of circle leg if can be provided, and make it with existing pen in conjunction with and reach, surpass the function of common compasses, then many problems will be readily solved!

The utility model is just for addressing the above problem, and design provide center of circle leg---" using litter compasses device " for pen arbitrarily more.

It mainly is made up of " slide bar " and " pen card " two big parts, " slide bar " again by: sliding tray, turn to pin, turn to three critical pieces formations of pin (seeing view 1 for details).During use pen is put into " pen card " change then its in the position of " sliding tray " and with the angle of " slide bar ", transfer to required radius after, fix with " gim peg " (promptly 6).The utility model both can make " slide bar " separately perpendicular to the plane, and also pen and " turning to pin " also can make pen and " turning to pin " while perpendicular to same plane (to satisfy the vertical usability of drawing pen etc., as Fig. 2,3) simultaneously perpendicular to the plane.

Advantage and the effect of comparing the utility model with prior art are embodied in following main aspect: at first, overcome center of circle leg in the use and slide, thereby and can make two legs improve accuracy greatly perpendicular to same plane simultaneously; Secondly because another leg appointed by the user, thereby make the color of painting can satisfy any wish of user fully; The 3rd, the composition structure of " plotter " will be greatly simplified in application of the present utility model, save a large amount of natural resources and social resources, reduce cost, price many-sided benefits such as realization resource, enterprise, consumer.

Below in conjunction with Figure of description the utility model is further specified

Fig. 1 is view of the present utility model, part sectioned view.

Fig. 2 makes " slide bar " independent use schematic diagram perpendicular to the plane.

Fig. 3 makes " slide bar " and pen simultaneously perpendicular to conplane use schematic diagram.

Following content respectively represented in code name in the accompanying drawing: 1. 2. cards of slide bar, 3. sliding trays 4. turn to pin 5. to turn to pin 6. gim pegs 7. pen arbitrarily.

In Fig. 1, pen card (2) places and is fixed on sliding tray (3) by gim peg (6) and is used for fixing any pen (7) and regulates radius.Turn to pin (4) but left-right rotation, but the elasticity at knot mouthful place should suit to have only with record book in accordion form is moving and can make it degree of rotation.Turn to the rotation direction of pin (5) and rotate pin (4) on the contrary.

In Fig. 2, pen inserted and fix with gim peg (6) after pen card (2) back is adjusted the angle of pen and slide bar (1) and pen card (2) relative position in the sliding tray is transferred to required radius again.

In Fig. 3, on the using method basis of Fig. 2, bending turns to pin (4) to make it perpendicular to the plane, can make pen and vertical and same plane of " turning to pin " while.

Claims

1. use the Slide rod type compass device one kind, it is mainly formed, be it is characterized in that by " slide bar " and " pen card " two parts more: " slide bar " by: sliding tray, turn to pin, turn to three critical pieces formations of pin

2. according to claim 1ly many use the Slide rod type compass device, it is characterized in that: the pen card is limited to and slides in the sliding tray and rotate.

3. according to claim 1ly many use the Slide rod type compass device, it is characterized in that: turn to pin and the rotation that turns to pin vertical mutually on direction (but turn to the pin left-right rotation, turn to the pin can the front and back rotation).
