Description

Novel compasses

Technical Field

The utility model belongs to the technical field of stationery, concretely relates to novel compasses.

Background

Compasses are used for drawing circles or strings in mathematics and drawing, and are commonly used for drawing rulers and compasses. The compasses are made of metal, plastic and the like, and comprise two parts which are connected through a hinge and can be adjusted. In the prior art, the compasses comprise a pen point, a rotating shaft, compass support legs, a ruler, a hinge, a pen body, a pen point, a compass tip and a small lug, wherein the lower end of the pen point is inserted and connected at the upper end of the pen body, the lower end of the pen body is in threaded connection at the upper end of the pen point, the flush end of the small lug is welded in the middle of the outer side of the compass support legs, and the lower end of the compass support legs is clamped and connected at the upper end of the compass tip. The centre of gravity of the existing compasses is easily stressed by a user unevenly, so that the compasses are easy to deviate, and the produced drawing is not accurate enough.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough of prior art is overcome to aim at, a novel compasses is provided.

In order to solve the technical problem, the utility model discloses a technical scheme as follows:

the utility model provides a novel compasses, includes the compasses pole, the cover has the weighting piece on the compasses pole, is equipped with the recess on the compasses pole, the weighting piece below is connected with the ring carrier, is equipped with stop screw on the ring carrier, and it has the compasses arm to keep away from stop screw end hinged joint on the ring carrier, compasses arm top is connected and is provided with the holder, be equipped with adjusting screw between compasses arm and holder, be equipped with the screens screw on the holder.

As an optimized technical scheme of the utility model, the lightening hole has been seted up at compasses arm middle part.

As an optimized technical proposal of the utility model, the bottom end of the compass rod is provided with a storage box.

As an optimal technical scheme of the utility model, be equipped with the round hole on the holder, the round hole is connected with the pencil, the round hole diameter is greater than the pencil diameter.

Compared with the prior art, the utility model has the advantages of it is following:

the utility model discloses a novel compasses, install on the compasses pole and set up the lightening hole on the compasses arm through setting up the weight, can make the focus concentrate on the compasses pole, make the stable in structure of compasses, the centre of a circle can not take place the skew during drawing a circle, the mapping is more pleasing to the eye, can remove along the recess on the compasses pole through setting up the ring carrier on the compasses pole, and fix its position through stop screw, make the circle of drawing scope of compasses bigger for ordinary compasses, the compasses arm is installed on the ring carrier, can realize 90 degrees rotations, the holder is installed on the compasses arm simultaneously, the rotation that can realize 180 degrees makes the radius control range of drawing a circle bigger. Adjusting screw is used for the position of fixed holder, and the screens screw is used for fixed pencil, adjusts through the cooperation between the three screw on the compasses for the compasses have simple structure, and the centre of a circle is stable, draw the big advantage of circle radius control range, because adjustable between the ring carrier of compasses, compasses arm and the holder, can accomodate into the size of compasses pole with it when accomodating the compasses, accomodate the picture like the compasses and show, the structure is ingenious easily to carry.

In the figure: 1. a compass bar; 2. a weighting block; 3. a limit screw; 4. an annular support; 5. a compass arm; 6. a pencil; 7. a clamping member; 8. an adjusting screw; 9. a clamping screw; 10. a pen core box; 11. a circular hole; 12. and (4) a groove.

Detailed Description

The present invention will be further illustrated by the following specific examples, which are carried out on the premise of the technical scheme of the present invention, and it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.

As shown in the attached drawing, the novel compasses comprise a compass rod 1, wherein a weighting block 2 is sleeved on the compass rod 1, a groove 12 is formed in the compass rod 1, an annular support 4 is connected to the lower side of the weighting block 2, a limit screw 3 is arranged on the annular support 4, the end, away from the limit screw 3, of the annular support 4 is hinged to a compass arm 5, a lightening hole is formed in the middle of the compass arm 5, a clamping piece 7 is connected to the top of the compass arm 5, a round hole 11 is formed in the clamping piece 7, the round hole 11 is connected with a pencil 6, the diameter of the round hole 11 is larger than that of the pencil 6, an adjusting screw 8 is arranged between the compass arm 5 and the clamping piece 7, a clamping screw 9 is arranged on the clamping piece 7, and an object placing box 10 is arranged at the bottom end of the compass rod 1.

Specifically, different from ordinary compasses, install the weight on the compasses pole and set up the lightening hole on the compasses arm, can make the focus concentrate on the compasses pole, make the stable in structure of compasses, the centre of a circle can not take place the skew during the drawing of circle, the mapping is more pleasing to the eye, ring carrier on the compasses pole can move along the recess on the compasses pole, and fix its position through stop screw, make the circle range of drawing of compasses bigger for ordinary compasses, the compasses arm is installed on ring carrier, can realize 90 degrees rotations, the holder is installed on the compasses arm simultaneously, the rotation that can realize 180 degrees makes the radius control range of drawing the circle bigger. Adjusting screw is used for the position of fixed holder, and the screens screw is used for fixed pencil, adjusts through the cooperation between the three screw on the compasses for the compasses have simple structure, and the centre of a circle is stable, draw the big advantage of circle radius control range, because adjustable between the ring carrier of compasses, compasses arm and the holder, can accomodate into the size of compasses pole with it when accomodating the compasses, accomodate the picture like the compasses and show, the structure is ingenious easily to carry.
