Abstract
The utility model relates to a mathematics learning tool is used in teaching, including first lock body and second lock body, be equipped with a plurality of telescopic links in the first lock body, the telescopic link right side is equipped with the spring, the spring left side is equipped with the ejector pad, be equipped with the rotary rod on the second lock body, rotary rod both ends symmetry is equipped with the lug. The utility model discloses a set up the telescopic link, the more convenient user's logarithmic word that lets carries out the plus -minus, through setting up the rotary rod, better opening and shutting to first lock body and second lock body is controlled, has increased the number of times that the user moved the brain and started, has increased the enjoyment of study, and simple structure, reasonable in design, convenient operation, safe and reliable.
Description
Technical field
The utility model relates to education sector, particularly relates to a kind of teaching mathematical studying instrument.
Background technology
Along with the development of society, education is also more and more paid attention to by people, particularly to the education of children, more should do from little, the existing mathematical tool to Primary School Children education is varied, but principle more complicated, interest is not strong, and operate inconvenience, and hand brain can not combine, thus learning efficiency is reduced, learning interest declines.
Utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, provides a kind of teaching mathematical studying instrument.
The utility model is achieved through the following technical solutions:
Mathematical studying instrument is used in a kind of teaching, comprises the first lock body and the second lock body, is provided with multiple expansion link in described first lock body, spring is provided with on the right side of described expansion link, be provided with pushing block on the left of described spring, described second lock body is provided with swingle, and described swingle two ends are arranged with projection.
As optimal technical scheme of the present utility model, described swingle is articulated and connected on the second lock body.
As optimal technical scheme of the present utility model, described expansion link and swingle are ten, and are evenly distributed on the first lock body and the second lock body.
As optimal technical scheme of the present utility model, described expansion link and the first lock body are slidably connected.
As the preferred technical scheme of the utility model, it is 10 newton that the thrust of described expansion link is added summation.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by arranging expansion link, user is allowed to add and subtract numeral more easily, by arranging swingle, better the first lock body and the second lock body folding are controlled, add the number of times that user beats one's brains and starts, add the enjoyment of study, and structure is simple, reasonable in design, easy to operate, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, the first lock body, 2, pushing block, 3, spring, 4, expansion link, 5, projection, the 6, second lock body, 7, swingle.
Specific embodiments
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, 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 explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Mathematical studying instrument is used in a kind of teaching, comprise the first lock body 1 and the second lock body 6, multiple expansion link 4 is provided with in described first lock body 1, it is 10 newton that the thrust of described expansion link 4 is added summation, described expansion link 4 and the first lock body 1 are slidably connected, spring 3 is provided with on the right side of described expansion link 4, pushing block 2 is provided with on the left of described spring 3, described second lock body 6 is provided with swingle 7, described swingle 7 is articulated and connected on the second lock body 6, described expansion link 4 and swingle 7 are ten, and be evenly distributed on the first lock body 1 and the second lock body 6, described swingle 7 two ends are arranged with projection 5.
During onsite application, first lock body 1 and the second lock body 6 are integrated, form a complete lock, promote pushing block 2, expansion link 4 is released to the right, and expansion link 4 promotes swingle 7 and rotates, and the power promoting swingle 7 applying when expansion link 4 is 10 Newtonian times, lock is opened, thus increases the ability that counts of pupil's units addition.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
