Abstract
The utility model discloses a multifunctional learning system capable of stimulating learning interests. A plotter comprises a positioning leg, a positioning pin, a painting brush leg, a painting brush, a painting brush holding device, a spring, an adjusting knob and a knob. Due to the fact that the spring is arranged inside the painting brush holding device, the painting brush is capable of being retracted moderately according to the physical strength of hand, the damage degree of the painting brush is reduced and the wholeness of a drawing is guaranteed. The positioning pin can be further changed to be in a magnet type or in a sucker type so that a pair of compasses can better meet different needs. The multifunctional learning system capable of stimulating learning interests has the advantages of being simple, practical, low in cost and good in practicality.
Description
Technical field
The utility model belongs to the instruments used for education field, relates in particular to a kind of multifunctional learning system that can arouse the interest in study.
Background technology
In modern teaching, especially in the teaching of mathematics or geometry, to need to use the aids such as set square, ruler, compasses, existing compasses location is moved back and is stylus structure, the paintbrush bare terminal end is that clamping screw or other add and hold device, and existing compasses in use easily cause fractureing of paintbrush, also can cause the material to required picture to cause damage, affected the effect of teaching, and function singleness, be unfavorable for teaching.
The utility model content
For paintbrush frangibility and the paintbrush leg that exists for existing compasses causes damage to material, the present invention proposes a kind of multifunctional learning system that can arouse the interest in study.
The utility model is achieved in that described plotter comprises location leg, pilot pin, paintbrush leg, paintbrush, paintbrush clamping device, spring, adjustment knob, knob; Location leg and paintbrush leg link together by a fixed axis, the following knob that pilot pin is fixed in the location leg by extruding also is fixed on the axle, the paintbrush clamping device is bolted on the paintbrush leg, it is inner that paintbrush is positioned at the paintbrush clamping device, the top of adjusting knob and paintbrush clamping device is threaded connection, adjust knob for the screw thread on band and the paintbrush clamping device is complementary, it is characterized in that, the inside of paintbrush clamping device is equipped with spring.
Further, the diameter of the diameter of spring and paintbrush and adjustment knob is close.
Further, described spring, paintbrush directly contact, and the diameter of paintbrush is greater than the diameter of spring, and the diameter of knob is greater than the diameter of spring.
Further, described pilot pin adopts magnet-type or sucked type.
The utility model provides can arouse the interest in study the multifunctional learning system, advantage is: the existence of paintbrush clamping device contained spring, so that paintbrush can be according to the size of hand-power amount, inside contracting of appropriateness, less its degree of losing, guaranteed the integrality of drawing, pilot pin can change to magnet-type or sucked type in addition, is that compasses better meet different requirements.This invention is simple and practical, and cost is lower, and good practicality is arranged.
Description of drawings
Fig. 1 be the utility model provide can arouse the interest in study the structural representation of multifunctional learning system.
Among the figure: 1, location leg 11, pilot pin 2, paintbrush leg 21 paintbrushes 22, paintbrush clamping device 23, spring 24, adjustment knob 3, knob.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1 shows that the utility model provides can arouse the interest in study the structure of multifunctional learning system.For convenience of explanation, only show the part relevant with the utility model.This can arouse the interest in study the multifunctional learning system architecture as follows:
Location leg 1 and paintbrush leg 2 link together by a fixed axis, the following knob 3 that pilot pin is fixed in location leg 1 by extruding also is fixed on the axle, paintbrush clamping device 22 is bolted on paintbrush leg 2, paintbrush 21 is positioned at paintbrush clamping device 22 inside, the top of adjusting knob 24 and paintbrush clamping device 22 is threaded connection, adjusting knob 24 is complementary for the screw thread on band and the paintbrush clamping device 22, be used for adjusting the length of paintbrush 21, spring 23 is positioned at the inside of paintbrush clamping device 22, suitable with the inner space of paintbrush clamping device 22, the diameter of the diameter of spring 23 and paintbrush 21 and adjustment knob 24 is close.Spring 23, paintbrush 21 directly contact, and the diameter of paintbrush 21 is greater than the diameter of spring 23, and the diameter of knob 24 is greater than the diameter of spring 23.
Multifunctional learning system that can arouse the interest in study provided by the invention, practical approach is as follows: at first paintbrush 21 is put into paintbrush clamping device 22, knob 24 is adjusted in turn, adjust knob 24 by turn and force spring 23 extruding paintbrushes 21, be paintbrush 21 expose suitable from length, pilot pin 11 is positioned over drawing or other position that need to draw that needs picture shape with hand grip knob 3, then the strength that relies on hand, turning knob 3 draws circle or the arc that needs, because the existence of spring 23, in the use procedure of compasses, paintbrush can be according to the size of hand-power amount, can appropriateness inside contract, reduced to a certain extent the degree of losing of paintbrush 21, guaranteed the success rate of figure, the pin of pilot pin 11 can be replaced by magnet-type or sucked type in addition, can allow compasses better meet different requirements.
The utility model provides can arouse the interest in study the multifunctional learning system, advantage is: the existence of paintbrush clamping device 22 contained springs 23, so that paintbrush 21 can be according to the size of hand-power amount, inside contracting of appropriateness, less its degree of losing, guaranteed the integrality of drawing, pilot pin 11 can change to magnet-type or sucked type in addition, is that compasses better meet different requirements.This invention is simple and practical, and cost is lower, and good practicality is arranged.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
