Description
Technical Field
The invention relates to a multifunctional teaching aid for measuring length and angle and shaping patterns, and belongs to the field of teaching aids.
Background
The teaching aid is a real object aiming at spreading science and technology and educating people, and is an indispensable device in teenager science and technology activities. But present teaching aid function is all more single, needs multiple teaching aid cooperation to use usually in the teaching experiment, not only inconvenient carrying, influences the demonstration effect moreover. Traditional teaching aids in the industry are single function teaching aids, such as rulers, protractors and compasses for rounding, and can only perform single actions. This kind of traditional type teaching aid molding is different, and the mr of being not convenient for carries, and simultaneously, modern education requires the mr to make various geometric figure, also does not make things convenient for the mr to accomodate when the end. Therefore, the multifunctional teaching aid is particularly important, not only solves the problem that a plotting teacher walks with large and small tools, but also increases the interest of learning and drives the enthusiasm of students.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a multifunctional teaching aid for measuring length and angle and shaping patterns, so that the technical problems are solved.
In order to achieve the purpose, the invention adopts the technical scheme that: a multifunctional teaching aid for measuring length and angle and shaping patterns comprises a holding end head; one side of the holding end is connected with the fixed seat; the first compass leg and the second compass leg are connected to the fixed seat through the fixed screws by the fixed seat; the first compass leg is a compass leg with a measuring scale function; a retractable protractor is arranged between the second compass leg and the first compass leg; the starting point of the protractor at one end of the retractable protractor is fixedly connected to the inner side face of the first compass leg; the other end of the retractable protractor penetrates through a slotted hole formed in the second compass leg and is fixedly connected with the fixed seat.
Furthermore, the head end of the first compass leg is a hinged end with a connecting hole, and a groove is formed in the hinged end of the first compass leg and used for embedding the second compass leg; and a connecting hole is formed in the second compass leg.
Furthermore, a square insertion groove opening is formed in the position, connected with the storable protractor, of the fixed seat, and an arc-shaped groove channel is formed in the fixed seat.
Further, the arc length of arc channel is unanimous with the maximum motion angle of the vertical axis of teaching aid and compasses leg one.
The invention has the beneficial effects that: the invention solves the problem of single functionality of the traditional teaching aid, provides the drawing and functions required by teachers or students in the daily learning process: circle, straight line and measurement angle; the multifunctional teaching aid solves the problem of the other types of models of most novel multifunctional teaching aids, is easier to be accepted by the public and is simpler to carry.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the attachment of the compasses leg according to the invention;
fig. 3 is a schematic side view of the structure of the present invention.
In the figure: 1. the compass comprises a holding end, a holding end 2, a fixing seat 3, a fixing screw 4, a first compass leg 5, a first compass leg 6, a second compass leg 7, a retractable protractor 71 and an arc-shaped groove channel.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
As shown in fig. 1, 2 and 3, a multifunctional teaching aid for measuring length, angle and setting patterns comprises a holding end 1; one side of the holding end head 1 is connected with the fixed seat 2; the first compass leg 5 and the second compass leg 6 are connected to the fixed seat 2 through the fixed screw 3 by the fixed seat 2; the first compass leg 5 is a compass leg with a measuring scale function; an storable protractor 7 is arranged between the second compass leg 6 and the first compass leg 4; the protractor starting point 4 at one end of the retractable protractor 7 is fixedly connected to the inner side surface of the first compass leg 5; the other end of the retractable protractor 7 penetrates through a slotted hole formed in the second compass leg 6 and is fixedly connected with the fixed seat 2.
In the preferred embodiment, the head end of the first compass leg 5 is a hinged end with a connecting hole, and a groove is arranged on the hinged end and is used for embedding the second compass leg 6; and a connecting hole is formed in the second compass leg 6.
In the preferred embodiment, the position where the fixed seat 2 is connected to the storable protractor 7 is provided with a square socket opening, and the fixed seat 2 is provided with an arc-shaped channel 71 therein.
Preferably, the arc length of the arc-shaped groove channel 71 is consistent with the maximum movement angle of the teaching aid vertical axis and the first 5 compasses legs.
