Description
Technical Field
The invention relates to the technical field of office supplies, in particular to compasses.
Background
At present, in drawing teaching, a teacher needs to carry several necessary tools such as rulers, compasses and pencils simultaneously during teaching and learning of students, and the carrying is inconvenient and easy to omit. The existing compasses generally need to draw by means of other measuring tools, when making a circle, two feet of the compasses must be aligned to scales on a ruler or a set square firstly to determine the radius required by making the circle, and then the compasses are used for making the circle, so that the compasses are inconvenient to use. Moreover, the existing compasses have single function, and only one circle can be drawn at a time during drawing.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and provides the multifunctional compasses which integrate multiple functions, can reduce the carrying of drawing tools and can draw quickly and accurately.
The invention is realized by adopting the following technical scheme:
a multifunctional compass comprises a compass head, a first compass foot and a second compass foot which are hinged with the compass head, wherein the tail end of the first compass foot is provided with a compass tip, the tail end of the second compass foot is provided with a drawing pen, the multifunctional compass also comprises an arc-shaped scale, one end of the arc-shaped scale is fixedly connected with the first compass foot, the other end of the arc-shaped scale points to the second compass foot, and the lengths of the first compass foot and the second compass foot are fixed; a pen groove is formed in the side face of the first compass foot, and a gel pen is placed in the pen groove; the second compass foot is threaded with the drawing pen, a ruler groove is formed in the side face of the second compass foot, the ruler groove is trapezoidal, three trapezoidal rulers are placed inside the ruler groove, and the three trapezoidal rulers are connected end to form a triangular plate; the compass further comprises an auxiliary compass, wherein an elastic clamp is arranged on the auxiliary compass and used for clamping the first compass foot or the second compass foot.
Compared with the traditional compasses, the multifunctional compasses disclosed by the invention do not need to align two feet of the compasses with scales on a ruler or a set square when in circle making, so that the carrying of drawing tools is reduced, and the multifunctional compasses can be used for making circles and measuring the distance between the two points; the auxiliary compasses are provided, 1-3 circles can be drawn at one time, and the auxiliary compasses can be used independently; the pen groove for containing the gel ink pen is formed, so that omission is avoided; the ruler groove is used for containing the ruler, and the ruler can be combined into a set square for use.
Drawings
FIG. 1 is a schematic structural diagram of the multi-function compass according to the embodiment.
In the above figures: 1. a first compass foot; 11. a compass tip; 12. a pen slot; 2. a second compass foot; 21. a drawing pen; 22. a ruler groove; 3. a compass head; 4. an auxiliary compass; 5. an arc scale; 6. a straightedge; 61. a groove; 62. a claw is provided.
Detailed Description
Example 1
Figure 1 provides a multi-functional compass comprising a compass head 3, first and second compass feet 1, 2 hinged to the compass head 3, and an auxiliary compass 4.
The length of first compasses foot 1 and second compasses foot 2 is fixed, sets up arc scale 5 on the first compasses foot 1, the one end and the 1 fixed connection of first compasses foot of arc scale 5, the directional second compasses foot 2 of the other end. The arc-shaped scale 5 is marked with scale marks and diameter values or radius values corresponding to the scale marks. The second compass foot 2 is marked with a mark line, and when the mark line is coincident with the scale mark on the scale, the value of the scale mark is the diameter value or the radius value obtained by drawing by the compass in the state.
The auxiliary compass 4 is provided with two articulated compasses feet, the tail ends of the two compasses feet are provided with a sleeve 41, the side surface of the sleeve 41 is provided with a screwing screw rod 42, and the screwing screw rod 42 is used when an iron needle or a refill is replaced. The position of the head of the auxiliary compass 4 is provided with an elastic clamp 43 which can be clamped on the first compass foot or the second compass foot and can draw 1-3 circles at a time according to requirements. The auxiliary compass 4 has a shorter compass foot, can be used independently and is used for drawing a circle with a smaller diameter.
The end of the first compass foot 1 is fixedly provided with a compass tip 11, the side surface is provided with a pen slot 12, and a gel pen is placed in the pen slot 12.
The tail end of the second compass foot 2 is provided with a drawing pen 21, the drawing pen 21 is in threaded connection with the second compass foot 2, and the drawing pen 21 can be used independently after being unscrewed. The side of the second compass foot 2 is provided with a ruler groove 22, the ruler groove 22 is trapezoidal, three trapezoidal rulers 6 are placed inside the ruler, one end of each ruler 6 is provided with a groove 61, the other end of each ruler is provided with a claw 62 protruding outwards, and the three rulers can be combined into a set square through end-to-end connection.
In the present invention, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be understood broadly, and may be, for example, a fixed connection, a detachable connection, or an integral connection; they may be connected directly or indirectly through an intermediate. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
