Description

Use pencil more

The utility model relates to uses pencil more.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, and the big class of office appliance is write or the drawing appliance group, writing appliance and other articles for use combination technical group field.Be numbered B43L 29/00.

At present, the technology about writing appliance and the combination of other articles for use existing and that once had was all done very fruitful effort to many demands with pencil, also once designed many outstanding technical schemes.As declaring of the nineteen ninety-five Decree of Patent Office of China by Yang Xianlong, Granted publication number is CN2202645Y, China Patent No. (ZL) is: No. 94219379.2 utility model title is the utility model patent of " having interesting rotation pen ", the technical scheme that is adopted.Be a routine of great value invention aspect writing appliance and other articles for use combination technique, it has solved pen effectively and has had interesting problem.But still have some deficits, its also is difficult to solution and how allows pencil can write, setting-out, can draw round problem again.

The purpose of this utility model is to provide a kind of pencil of using more.How to allow to solve pencil can write, setting-out, can draw round problem again.

The purpose of this utility model is achieved in that this utility model uses pencil more.Mainly constitute by center of circle pin, picture round needle, hold-down screw, pencil, adjustment screw, slip ring, retainer ring.Its major part hold-down screw, center of circle pin, picture round needle are by selecting for use on the market.Retainer ring, slip ring, adjustment screw are made with the steel material.Pencil is made with timber.The utility model main body is made of retainer ring, slip ring and pencil, is fixed with center of circle pin on the retainer ring, and the slip ring upper end is fixed with the picture round needle; Below the picture round needle hold-down screw is arranged, is provided with adjustment screw in the middle of the slip ring, be painted with scale on the pencil.So just realized the purpose of this utility model.

The utility model has been compared three advantages and improvement with original writing appliance with other articles for use combination technique;

The first, because the utility model has designed retainer ring and center of circle pin in technical scheme, solve the problem of picture circle centralized positioning;

The second, because the utility model has designed scale and has been drawn on the pencil in technical scheme, solved the problem of drawing the radius of circle fixed length;

The 3rd, because the utility model has designed slip ring in technical scheme, solved the problem of drawing the elongated degree of bowlder setting-out.Thereby just can more effectively solve how to allow pencil can write, setting-out, can draw round problem again.

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is many main TV structure schematic diagrames with pencil of the present utility model;

Fig. 2 is a side-looking structural representation of using the slip ring of pencil of the present utility model more;

The numbering of parts explanation in the schematic diagram: 1 center of circle pin 2 is drawn round needle 3 hold-down screws 4 pencils 5 adjustment screw 6 slip rings 7 retainer rings

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in the figure, the multiplex pencil of the utility model. Mainly by center of circle pin (1), draw round needle (2), Hold-down screw (3), pencil (4), adjustment screw (5), slip ring (6), retainer ring (7) Consist of. Its major part hold-down screw (3), center of circle pin (1), picture round needle (2) are by market On select. Retainer ring (7), slip ring (6), adjustment screw (5) are made with Steel material. Plumbous Pen (4) is made with timber. The utility model main body is by retainer ring (7), slip ring (6) and lead Pen (4) consists of, and is fixed with center of circle pin (1) on the retainer ring (7), and slip ring (6) upper end is fixing Picture round needle (2) is arranged; Below the picture round needle (2) hold-down screw (3) is arranged, establishes in the middle of the slip ring (6) Adjustment screw (5) is arranged, and pencil is painted with scale on (4). So just realized order of the present utility model . Thereby just can solve how to allow pencil can write, setting-out, can draw round problem again.

Below by embodiment, the utility model is done more detailed description:

Embodiment 1, in use, if set up center of circle pin (1) on retainer ring (7), sets up picture round needle (2) at slip ring (6), uses hold-down screw (3) fixing mobile.Slip ring (6) is to the graduation mark of required radius length pencil (4), utilize adjustment screw (5), slip ring (6) is fixed on the pencil (4), just can be at the paper upper drawing circle finish and unload center of circle pin (1) and draw round needle (2), solution allows pencil can write, setting-out can be drawn round problem again like this.Thereby just can realize the purpose of this utility model.
